Zipline—Airbnb’s Declarative Feature Engineering Framework
Zipline is Airbnb’s data management platform specifically designed for ML use cases. Previously, ML practitioners at Airbnb spent roughly 60% of their time on collecting and writing transformations for machine learning tasks. Zipline reduces this task from months to days – by making the process declarative. It allows data scientists to easily define features in a simple configuration language. The framework then provides access to point-in-time correct features – for both – offline model training and online inference. In this talk we will describe the architecture of our system and the algorithm that makes the problem of efficient point-in-time correct feature generation, tractable.
The attendee will learn
Importance of point-in-time correct features for achieving better ML model performance
Importance of using change data capture for generating feature views
An algorithm – to efficiently generate features over change data. We use interval trees to efficiently compress time series features. The algorithm allows generating feature aggregates over this compressed representation.
A lambda architecture – that enables using the above algorithm – for online feature generation.
A framework, based on category theory, to understand how feature aggregations be distributed, and independently composed.
While the talk if fairly technical – we will introduce all the concepts from first principles with examples. Basic understanding of data-parallel distributed computation and machine learning might help, but are not required.

Zipline is Airbnb’s data management platform specifically designed for ML use cases. Previously, ML practitioners at Airbnb spent roughly 60% of their time on collecting and writing transformations for machine learning tasks. Zipline reduces this task from months to days. It allows users to define features in an easy-to-use configuration language, then provides access to the following features: resource efficient and point-in-time correct training set backfills and scheduled updates, feature visualizations and automatic data quality monitoring, feature availability in online scoring environment: batch and streaming with batch correction (lambda architecture), collaboration and sharing of features, and data ownership and management.
Spark powers many of Zipline’s features, especially offline tasks for efficient training set backfills and feature computation. This talk covers Ziplines architecture and the main problems that Zipline solves. Despite being widespread, there is no open source software to address these problems. As a result, we intend to open source our work.
Sawtooth Windows for Feature Aggregations
In this talk about zipline, we will introduce a new type of windowing construct called a sawtooth window. We will describe various properties about sawtooth windows that we utilize to achieve online-offline consistency, while still maintaining high-throughput, low-read latency and tunable write latency for serving machine learning features.We will also talk about a simple deployment strategy for correcting feature drift – due operations that are not “abelian groups”, that operate over change data.
Squirreling Away $640 Billion: How Stripe Leverages Flink for Change Data Cap...
Flink Forward San Francisco 2022.
Being in the payments space, Stripe requires strict correctness and freshness guarantees. We rely on Flink as the natural solution for delivering on this in support of our Change Data Capture (CDC) infrastructure. We heavily rely on CDC as a tool for capturing data change streams from our databases without critically impacting database reliability, scalability, and maintainability. Data derived from these streams is used broadly across the business and powers many of our critical financial reporting systems totalling over $640 Billion in payment volume annually. We use many components of Flink’s flexible DataStream API to perform aggregations and abstract away the complexities of stream processing from our downstreams. In this talk, we’ll walk through our experience from the very beginning to what we have in production today. We’ll share stories around the technical details and trade-offs we encountered along the way.

Frame - Feature Management for Productive Machine Learning
Presented at the ML Platforms Meetup at Pinterest HQ in San Francisco on August 16, 2018.
Abstract: At LinkedIn we observed that much of the complexity in our machine learning applications was in their feature preparation workflows. To address this problem, we built Frame, a shared virtual feature store that provides a unified abstraction layer for accessing features by name. Frame removes the need for feature consumers to deal directly with underlying data sources, which are often different across computing environments. By simplifying feature preparation, Frame has made ML applications at LinkedIn easier to build, modify, and understand.

Bighead: Airbnb’s End-to-End Machine Learning Platform with Krishna Puttaswa...
Airbnb has a wide variety of ML problems ranging from models on traditional structured data to models built on unstructured data such as user reviews, messages and listing images. The ability to build, iterate on, and maintain healthy machine learning models is critical to Airbnb’s success. Many ML Platforms cover data collection, feature engineering, training, deploying, productionalization, and monitoring but few, if any, do all of the above seamlessly.
Bighead aims to tie together various open source and in-house projects to remove incidental complexity from ML workflows. Bighead is built on Python and Spark and can be used in modular pieces as each ML problem presents unique challenges. Through standardization of the path to production, training environments and the methods for collecting and transforming data on Spark, each model is reproducible and iterable.
This talk covers the architecture, the problems that each individual component and the overall system aims to solve, and a vision for the future of machine learning infrastructure. It’s widely adapted in Airbnb and we have variety of models running in production. We have seen the overall model development time go down from many months to days on Bighead. We plan to open source Bighead to allow the wider community to benefit from our work.
Data engineering design patterns
There are patterns for things such as domain-driven design, enterprise architectures, continuous delivery, microservices, and many others.
But where are the data science and data engineering patterns?
Sometimes, data engineering reminds me of cowboy coding - many workarounds, immature technologies and lack of market best practices.
Unlocking the Power of Apache Flink: An Introduction in 4 Acts
"Today's consumers have come to expect timely and accurate information from the companies they do business with. Whether it's being alerted that someone just used your credit card to rent a car in Prague, or checking on the balance of your mobile data plan, it's not good enough to learn about yesterday's information today. We all expect the companies managing our data to be able to provide fully up-to-the-moment reporting.
Apache Flink is a battle-hardened stream processor widely used for demanding applications like these. Its performance and robustness are the result of a handful of core design principles: a shared-nothing architecture with local state, event-time processing, and state snapshots (for recovery). During this talk, we'll bring these principles to life with real-world examples and demos."
Modern ETL Pipelines with Change Data Capture
In this talk we’ll present how at GetYourGuide we’ve built from scratch a completely new ETL pipeline using Debezium, Kafka, Spark and Airflow, which can automatically handle schema changes. Our starting point was an error prone legacy system that ran daily, and was vulnerable to breaking schema changes, which caused many sleepless on-call nights. As most companies, we also have traditional SQL databases that we need to connect to in order to extract relevant data.
This is done usually through either full or partial copies of the data with tools such as sqoop. However another approach that has become quite popular lately is to use Debezium as the Change Data Capture layer which reads databases binlogs, and stream these changes directly to Kafka. As having data once a day is not enough anymore for our bussiness, and we wanted our pipelines to be resilent to upstream schema changes, we’ve decided to rebuild our ETL using Debezium.
We’ll walk the audience through the steps we followed to architect and develop such solution using Databricks to reduce operation time. By building this new pipeline we are now able to refresh our data lake multiple times a day, giving our users fresh data, and protecting our nights of sleep.
Where is my bottleneck? Performance troubleshooting in Flink
Flinkn Forward San Francisco 2022.
In this talk, we will cover various topics around performance issues that can arise when running a Flink job and how to troubleshoot them. We’ll start with the basics, like understanding what the job is doing and what backpressure is. Next, we will see how to identify bottlenecks and which tools or metrics can be helpful in the process. Finally, we will also discuss potential performance issues during the checkpointing or recovery process, as well as and some tips and Flink features that can speed up checkpointing and recovery times.

Operationalizing Machine Learning at Scale at Starbucks
As ML-driven innovations are propelled by the Self-Service capabilities in the Enterprise Data and Analytics Platform, teams face a significant entry barrier and productivity issues in moving from POCs to Operating ML-powered apps at scale in production.
Bootstrapping state in Apache Flink
Apache Flink is a popular stream computing framework for real-time stream computing. Many stream compute algorithms require trailing data in order to compute the intended result. One example is computing the number of user logins in the last 7 days. This creates a dilemma where the results of the stream program are incomplete until the runtime of the program exceeds 7 days. The alternative is to bootstrap the program using historic data to seed the state before shifting to use real-time data.
This talk will discuss alternatives to bootstrap programs in Flink. Some alternatives rely on technologies exogenous to the stream program, such as enhancements to the pub/sub layer, that are more generally applicable to other stream compute engines. Other alternatives include enhancements to Flink source implementations. Lyft is exploring another alternative using orchestration of multiple Flink programs. The talk will cover why Lyft pursued this alternative and future directions to further enhance bootstrapping support in Flink.

Data Day Texas 2017: Scaling Data Science at Stitch Fix
At Stitch Fix we have a lot of Data Scientists. Around eighty at last count. One reason why I think we have so many, is that we do things differently. To get their work done, Data Scientists have access to whatever resources they need (within reason), because they’re end to end responsible for their work; they collaborate with their business partners on objectives and then prototype, iterate, productionize, monitor and debug everything and anything required to get the output desired. They’re full data-stack data scientists!
The teams in the organization do a variety of different tasks:
- Clothing recommendations for clients.
- Clothes reordering recommendations.
- Time series analysis & forecasting of inventory, client segments, etc.
- Warehouse worker path routing.
- NLP.
… and more!
They’re also quite prolific at what they do -- we are approaching 4500 job definitions at last count. So one might be wondering now, how have we enabled them to get their jobs done without getting in the way of each other?
This is where the Data Platform teams comes into play. With the goal of lowering the cognitive overhead and engineering effort required on part of the Data Scientist, the Data Platform team tries to provide abstractions and infrastructure to help the Data Scientists. The relationship is a collaborative partnership, where the Data Scientist is free to make their own decisions and thus choose they way they do their work, and the onus then falls on the Data Platform team to convince Data Scientists to use their tools; the easiest way to do that is by designing the tools well.
In regard to scaling Data Science, the Data Platform team has helped establish some patterns and infrastructure that help alleviate contention. Contention on:
Access to Data
Access to Compute Resources:
Ad-hoc compute (think prototype, iterate, workspace)
Production compute (think where things are executed once they’re needed regularly)
For the talk (and this post) I only focused on how we reduced contention on Access to Data, & Access to Ad-hoc Compute to enable Data Science to scale at Stitch Fix. With that I invite you to take a look through the slides.

Data Day Texas 2017: Scaling Data Science at Stitch Fix
At Stitch Fix we have a lot of Data Scientists. Around eighty at last count. One reason why I think we have so many, is that we do things differently. To get their work done, Data Scientists have access to whatever resources they need (within reason), because they’re end to end responsible for their work; they collaborate with their business partners on objectives and then prototype, iterate, productionize, monitor and debug everything and anything required to get the output desired. They’re full data-stack data scientists!
The teams in the organization do a variety of different tasks:
- Clothing recommendations for clients.
- Clothes reordering recommendations.
- Time series analysis & forecasting of inventory, client segments, etc.
- Warehouse worker path routing.
- NLP.
… and more!
They’re also quite prolific at what they do -- we are approaching 4500 job definitions at last count. So one might be wondering now, how have we enabled them to get their jobs done without getting in the way of each other?
This is where the Data Platform teams comes into play. With the goal of lowering the cognitive overhead and engineering effort required on part of the Data Scientist, the Data Platform team tries to provide abstractions and infrastructure to help the Data Scientists. The relationship is a collaborative partnership, where the Data Scientist is free to make their own decisions and thus choose they way they do their work, and the onus then falls on the Data Platform team to convince Data Scientists to use their tools; the easiest way to do that is by designing the tools well.
In regard to scaling Data Science, the Data Platform team has helped establish some patterns and infrastructure that help alleviate contention. Contention on:
Access to Data
Access to Compute Resources:
Ad-hoc compute (think prototype, iterate, workspace)
Production compute (think where things are executed once they’re needed regularly)
For the talk (and this post) I only focused on how we reduced contention on Access to Data, & Access to Ad-hoc Compute to enable Data Science to scale at Stitch Fix. With that I invite you to take a look through the slides.

Accumulo Summit 2015: Building Aggregation Systems on Accumulo [Leveraging Ac...
Talk Abstract
Aggregation has long been a use case of Accumulo Iterators. Iterators' ability to reduce data during compaction and scanning can greatly simplify an aggregation system built on Accumulo. This talk will first review how Accumulo's Iterators/Combiners work in the context of aggregating values. I'll then step back and look at the abstraction of aggregation functions as commutative operations and the several benefits that result by making this abstraction. We will see how it becomes no harder to introduce powerful operations such as cardinality estimation and approximate top-k than it is to sum integers. I will show how to integrate these ideas into Accumulo with an example schema and Iterator. Finally, a practical aggregation use case will be discussed to highlight the concepts from the talk.

AWS December 2015 Webinar Series - Strategies to Quantify TCO & Optimize Cost...
AWS allows customers to save money and optimize costs in multiple ways. By adopting AWS, organizations can reduce capital expenses and shift to an operating model, improve business performance and drive savings over time. Organizations that adopt AWS have the tools to move from forecast-based capacity planning to an on-demand model with no termination fees or complex agreements. By moving to AWS, customers can reduce total cost of ownership (TCO) and continue to see increased savings over time. In addition to reducing TCO, AWS empowers customers to optimize costs by providing them tools and partner solutions that help them identify what they are consuming and the right size of the services that their business needs. They will use the services only when they are necessary for production. These solutions allow customers to pay not only for what they need but also only pay for the right capacity and time of consumption, reducing idle time and unnecessary sunk costs.
In this webinar, you will learn strategies directly from AWS Product Manager and understand how a customer (FINRA) used Splunk to develop a cost optimization model that helps to drive value and continued lower costs.
Learning Objectives:
Dive deeper into the economics of the cloud and understand how AWS can positively impact your organization
Learn how a customer gained real-time visibility into instance cost and usage to reduce spending
Who Should Attend:
IT managers, Sr. IT professionals, business decision makers, procurement managers, developers, sys admins, operations

Challenges in Data Analytics:
Different application scenarios need different storage solutions: HBASE is ideal for point query scenarios but unsuitable for multi-dimensional queries. MPP is suitable for data warehouse scenarios but engine and data are coupled together which hampers scalability. OLAP stores used in BI applications perform best for Aggregate queries but full scan queries perform at a sub-optimal performance. Moreover, they are not suitable for real-time analysis. These distinct systems lead to low resource sharing and need different pipelines for data and application management.

How we evolved data pipeline at Celtra and what we learned along the way
Presented at Data Science Meetup on 4/12/2018.
In this talk, Grega Kespret (head of analytics group) will present Celtra’s data analytics pipeline and how it evolved through the years - sometimes forward, sometimes backward. On this journey, we became early adopter of different technologies: BigQuery, Vertica (pre-join projections), Spark (version 0.5), Databricks (beta users) and Snowflake (one of the first users). As the business grew and the product evolved, volume and complexity of data increased ten-fold, as has the number of users generating insights from this data. How come BigQuery did not scale? Why was choosing Vertica a mistake for our use case, and what have we learned from it? What requirements did we have for the analytics database, why did we have to abandon MySQL, and why we finally chose Snowflake? This talk will be heavily opinionated and will describe our experience and learnings - what worked for us and what didn't.

5 Critical Steps to Clean Your Data Swamp When Migrating Off of Hadoop
In this session, learn how to quickly supplement your on-premises Hadoop environment with a simple, open, and collaborative cloud architecture that enables you to generate greater value with scaled application of analytics and AI on all your data. You will also learn five critical steps for a successful migration to the Databricks Lakehouse Platform along with the resources available to help you begin to re-skill your data teams.
Democratizing Data Quality Through a Centralized Platform
Bad data leads to bad decisions and broken customer experiences. Organizations depend on complete and accurate data to power their business, maintain efficiency, and uphold customer trust. With thousands of datasets and pipelines running, how do we ensure that all data meets quality standards, and that expectations are clear between producers and consumers? Investing in shared, flexible components and practices for monitoring data health is crucial for a complex data organization to rapidly and effectively scale.
At Zillow, we built a centralized platform to meet our data quality needs across stakeholders. The platform is accessible to engineers, scientists, and analysts, and seamlessly integrates with existing data pipelines and data discovery tools. In this presentation, we will provide an overview of our platform’s capabilities, including:
Giving producers and consumers the ability to define and view data quality expectations using a self-service onboarding portal
Performing data quality validations using libraries built to work with spark
Dynamically generating pipelines that can be abstracted away from users
Flagging data that doesn’t meet quality standards at the earliest stage and giving producers the opportunity to resolve issues before use by downstream consumers
Exposing data quality metrics alongside each dataset to provide producers and consumers with a comprehensive picture of health over time
Learn to Use Databricks for Data Science
Data scientists face numerous challenges throughout the data science workflow that hinder productivity. As organizations continue to become more data-driven, a collaborative environment is more critical than ever — one that provides easier access and visibility into the data, reports and dashboards built against the data, reproducibility, and insights uncovered within the data.. Join us to hear how Databricks’ open and collaborative platform simplifies data science by enabling you to run all types of analytics workloads, from data preparation to exploratory analysis and predictive analytics, at scale — all on one unified platform.
Why APM Is Not the Same As ML Monitoring
Application performance monitoring (APM) has become the cornerstone of software engineering allowing engineering teams to quickly identify and remedy production issues. However, as the world moves to intelligent software applications that are built using machine learning, traditional APM quickly becomes insufficient to identify and remedy production issues encountered in these modern software applications.
As a lead software engineer at NewRelic, my team built high-performance monitoring systems including Insights, Mobile, and SixthSense. As I transitioned to building ML Monitoring software, I found the architectural principles and design choices underlying APM to not be a good fit for this brand new world. In fact, blindly following APM designs led us down paths that would have been better left unexplored.
In this talk, I draw upon my (and my team’s) experience building an ML Monitoring system from the ground up and deploying it on customer workloads running large-scale ML training with Spark as well as real-time inference systems. I will highlight how the key principles and architectural choices of APM don’t apply to ML monitoring. You’ll learn why, understand what ML Monitoring can successfully borrow from APM, and hear what is required to build a scalable, robust ML Monitoring architecture.
The Function, the Context, and the Data—Enabling ML Ops at Stitch Fix
Autonomy and ownership are core to working at Stitch Fix, particularly on the Algorithms team. We enable data scientists to deploy and operate their models independently, with minimal need for handoffs or gatekeeping. By writing a simple function and calling out to an intuitive API, data scientists can harness a suite of platform-provided tooling meant to make ML operations easy. In this talk, we will dive into the abstractions the Data Platform team has built to enable this. We will go over the interface data scientists use to specify a model and what that hooks into, including online deployment, batch execution on Spark, and metrics tracking and visualization.
Stage Level Scheduling Improving Big Data and AI Integration
In this talk, I will dive into the stage level scheduling feature added to Apache Spark 3.1. Stage level scheduling extends upon Project Hydrogen by improving big data ETL and AI integration and also enables multiple other use cases. It is beneficial any time the user wants to change container resources between stages in a single Apache Spark application, whether those resources are CPU, Memory or GPUs. One of the most popular use cases is enabling end-to-end scalable Deep Learning and AI to efficiently use GPU resources. In this type of use case, users read from a distributed file system, do data manipulation and filtering to get the data into a format that the Deep Learning algorithm needs for training or inference and then sends the data into a Deep Learning algorithm. Using stage level scheduling combined with accelerator aware scheduling enables users to seamlessly go from ETL to Deep Learning running on the GPU by adjusting the container requirements for different stages in Spark within the same application. This makes writing these applications easier and can help with hardware utilization and costs.
There are other ETL use cases where users want to change CPU and memory resources between stages, for instance there is data skew or perhaps the data size is much larger in certain stages of the application. In this talk, I will go over the feature details, cluster requirements, the API and use cases. I will demo how the stage level scheduling API can be used by Horovod to seamlessly go from data preparation to training using the Tensorflow Keras API using GPUs.
The talk will also touch on other new Apache Spark 3.1 functionality, such as pluggable caching, which can be used to enable faster dataframe access when operating from GPUs.
Simplify Data Conversion from Spark to TensorFlow and PyTorch
In this talk, I would like to introduce an open-source tool built by our team that simplifies the data conversion from Apache Spark to deep learning frameworks.
Imagine you have a large dataset, say 20 GBs, and you want to use it to train a TensorFlow model. Before feeding the data to the model, you need to clean and preprocess your data using Spark. Now you have your dataset in a Spark DataFrame. When it comes to the training part, you may have the problem: How can I convert my Spark DataFrame to some format recognized by my TensorFlow model?
The existing data conversion process can be tedious. For example, to convert an Apache Spark DataFrame to a TensorFlow Dataset file format, you need to either save the Apache Spark DataFrame on a distributed filesystem in parquet format and load the converted data with third-party tools such as Petastorm, or save it directly in TFRecord files with spark-tensorflow-connector and load it back using TFRecordDataset. Both approaches take more than 20 lines of code to manage the intermediate data files, rely on different parsing syntax, and require extra attention for handling vector columns in the Spark DataFrames. In short, all these engineering frictions greatly reduced the data scientists’ productivity.
The Databricks Machine Learning team contributed a new Spark Dataset Converter API to Petastorm to simplify these tedious data conversion process steps. With the new API, it takes a few lines of code to convert a Spark DataFrame to a TensorFlow Dataset or a PyTorch DataLoader with default parameters.
In the talk, I will use an example to show how to use the Spark Dataset Converter to train a Tensorflow model and how simple it is to go from single-node training to distributed training on Databricks.
Scaling your Data Pipelines with Apache Spark on Kubernetes
There is no doubt Kubernetes has emerged as the next generation of cloud native infrastructure to support a wide variety of distributed workloads. Apache Spark has evolved to run both Machine Learning and large scale analytics workloads. There is growing interest in running Apache Spark natively on Kubernetes. By combining the flexibility of Kubernetes and scalable data processing with Apache Spark, you can run any data and machine pipelines on this infrastructure while effectively utilizing resources at disposal.
In this talk, Rajesh Thallam and Sougata Biswas will share how to effectively run your Apache Spark applications on Google Kubernetes Engine (GKE) and Google Cloud Dataproc, orchestrate the data and machine learning pipelines with managed Apache Airflow on GKE (Google Cloud Composer). Following topics will be covered: – Understanding key traits of Apache Spark on Kubernetes- Things to know when running Apache Spark on Kubernetes such as autoscaling- Demonstrate running analytics pipelines on Apache Spark orchestrated with Apache Airflow on Kubernetes cluster.
Scaling and Unifying SciKit Learn and Apache Spark Pipelines
Pipelines have become ubiquitous, as the need for stringing multiple functions to compose applications has gained adoption and popularity. Common pipeline abstractions such as “fit” and “transform” are even shared across divergent platforms such as Python Scikit-Learn and Apache Spark.
Scaling pipelines at the level of simple functions is desirable for many AI applications, however is not directly supported by Ray’s parallelism primitives. In this talk, Raghu will describe a pipeline abstraction that takes advantage of Ray’s compute model to efficiently scale arbitrarily complex pipeline workflows. He will demonstrate how this abstraction cleanly unifies pipeline workflows across multiple platforms such as Scikit-Learn and Spark, and achieves nearly optimal scale-out parallelism on pipelined computations.
Attendees will learn how pipelined workflows can be mapped to Ray’s compute model and how they can both unify and accelerate their pipelines with Ray.
Redis + Apache Spark = Swiss Army Knife Meets Kitchen Sink
We want to present multiple anti patterns utilizing Redis in unconventional ways to get the maximum out of Apache Spark.All examples presented are tried and tested in production at Scale at Adobe. The most common integration is spark-redis which interfaces with Redis as a Dataframe backing Store or as an upstream for Structured Streaming. We deviate from the common use cases to explore where Redis can plug gaps while scaling out high throughput applications in Spark.
Niche 1 : Long Running Spark Batch Job – Dispatch New Jobs by polling a Redis Queue
· Why?
o Custom queries on top a table; We load the data once and query N times
· Why not Structured Streaming
· Working Solution using Redis
Niche 2 : Distributed Counters
· Problems with Spark Accumulators
· Utilize Redis Hashes as distributed counters
· Precautions for retries and speculative execution
· Pipelining to improve performance
Re-imagine Data Monitoring with whylogs and Spark
In the era of microservices, decentralized ML architectures and complex data pipelines, data quality has become a bigger challenge than ever. When data is involved in complex business processes and decisions, bad data can, and will, affect the bottom line. As a result, ensuring data quality across the entire ML pipeline is both costly, and cumbersome while data monitoring is often fragmented and performed ad hoc. To address these challenges, we built whylogs, an open source standard for data logging. It is a lightweight data profiling library that enables end-to-end data profiling across the entire software stack. The library implements a language and platform agnostic approach to data quality and data monitoring. It can work with different modes of data operations, including streaming, batch and IoT data.
In this talk, we will provide an overview of the whylogs architecture, including its lightweight statistical data collection approach and various integrations. We will demonstrate how the whylogs integration with Apache Spark achieves large scale data profiling, and we will show how users can apply this integration into existing data and ML pipelines.
Raven: End-to-end Optimization of ML Prediction Queries
Machine learning (ML) models are typically part of prediction queries that consist of a data processing part (e.g., for joining, filtering, cleaning, featurization) and an ML part invoking one or more trained models. In this presentation, we identify significant and unexplored opportunities for optimization. To the best of our knowledge, this is the first effort to look at prediction queries holistically, optimizing across both the ML and SQL components.
We will present Raven, an end-to-end optimizer for prediction queries. Raven relies on a unified intermediate representation that captures both data processing and ML operators in a single graph structure.
This allows us to introduce optimization rules that
(i) reduce unnecessary computations by passing information between the data processing and ML operators
(ii) leverage operator transformations (e.g., turning a decision tree to a SQL expression or an equivalent neural network) to map operators to the right execution engine, and
(iii) integrate compiler techniques to take advantage of the most efficient hardware backend (e.g., CPU, GPU) for each operator.
We have implemented Raven as an extension to Spark’s Catalyst optimizer to enable the optimization of SparkSQL prediction queries. Our implementation also allows the optimization of prediction queries in SQL Server. As we will show, Raven is capable of improving prediction query performance on Apache Spark and SQL Server by up to 13.1x and 330x, respectively. For complex models, where GPU acceleration is beneficial, Raven provides up to 8x speedup compared to state-of-the-art systems. As part of the presentation, we will also give a demo showcasing Raven in action.
Processing Large Datasets for ADAS Applications using Apache Spark
Semantic segmentation is the classification of every pixel in an image/video. The segmentation partitions a digital image into multiple objects to simplify/change the representation of the image into something that is more meaningful and easier to analyze [1][2]. The technique has a wide variety of applications ranging from perception in autonomous driving scenarios to cancer cell segmentation for medical diagnosis.
Exponential growth in the datasets that require such segmentation is driven by improvements in the accuracy and quality of the sensors generating the data extending to 3D point cloud data. This growth is further compounded by exponential advances in cloud technologies enabling the storage and compute available for such applications. The need for semantically segmented datasets is a key requirement to improve the accuracy of inference engines that are built upon them.
Streamlining the accuracy and efficiency of these systems directly affects the value of the business outcome for organizations that are developing such functionalities as a part of their AI strategy.
This presentation details workflows for labeling, preprocessing, modeling, and evaluating performance/accuracy. Scientists and engineers leverage domain-specific features/tools that support the entire workflow from labeling the ground truth, handling data from a wide variety of sources/formats, developing models and finally deploying these models. Users can scale their deployments optimally on GPU-based cloud infrastructure to build accelerated training and inference pipelines while working with big datasets. These environments are optimized for engineers to develop such functionality with ease and then scale against large datasets with Spark-based clusters on the cloud.
Massive Data Processing in Adobe Using Delta Lake
At Adobe Experience Platform, we ingest TBs of data every day and manage PBs of data for our customers as part of the Unified Profile Offering. At the heart of this is a bunch of complex ingestion of a mix of normalized and denormalized data with various linkage scenarios power by a central Identity Linking Graph. This helps power various marketing scenarios that are activated in multiple platforms and channels like email, advertisements etc. We will go over how we built a cost effective and scalable data pipeline using Apache Spark and Delta Lake and share our experiences.

Machine Learning CI/CD for Email Attack Detection
Detecting advanced email attacks at scale is a challenging ML problem, particularly due to the rarity of attacks, adversarial nature of the problem, and scale of data. In order to move quickly and adapt to the newest threat we needed to build a Continuous Integration / Continuous Delivery pipeline for the entire ML detection stack. Our goal is to enable detection engineers and data scientists to make changes to any part of the stack including joined datasets for hydration, feature extraction code, detection logic, and develop/train ML models.
In this talk, we discuss why we decided to build this pipeline, how it is used to accelerate development and ensure quality, and dive into the nitty-gritty details of building such a system on top of an Apache Spark + Databricks stack.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.
Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”

【业务选择办理准则】
一、工作未确定，回国需先给父母、亲戚朋友看下文凭的情况，办理一份就读学校的毕业证【Q微信741003700】文凭即可
二、回国进私企、外企、自己做生意的情况，这些单位是不查询毕业证真伪的，而且国内没有渠道去查询国外文凭的真假，也不需要提供真实教育部认证。鉴于此，办理一份毕业证【微信741003700】即可
三、进国企，银行，事业单位，考公务员等等，这些单位是必需要提供真实教育部认证的，办理教育部认证所需资料众多且烦琐，所有材料您都必须提供原件，我们凭借丰富的经验，快捷的绿色通道帮您快速整合材料，让您少走弯路。
留信网认证的作用:
1:该专业认证可证明留学生真实身份

Zipline - A Declarative Feature Engineering Framework
- 1. Zipline Declarative Feature Engineering Framework Nikhil Simha nikhil.simha@airbnb.com
- 3. “We recognize that a mature system might end up being (at most) 5% machine learning code and (at least) 95% glue code” – Sculley, NIPS 2015
- 4. • Question – “glue code” • Imperative process -> Declarative specification • Months to days • With just the DS Goal
- 5. • 60 – 70% • Good data with okay/simple model Feature Engineering
- 7. • Part of Bighead • Supervised learning • Structured data vs unstructured data • systems problem vs. math problem Context
- 8. What makes Feature Engineering Hard?
- 9. • Features + Algorithm • Data • Continuously Arriving Everything changes
- 10. Your typical Data Warehouse
- 12. An example ● Predict likelihood of you liking a particular Indian restaurant ● Total visits to Indian places last month ● Average rating of the restaurant last year ● They are all aggregations
- 13. An example ● Predict likelihood of you liking a particular Indian restaurant ● Total visits to Indian places last month ● Operation: Count, Input: Visit, Window = 1month, ● Source: Check-in stream ● Average rating of the restaurant ● Operation: AVG, Input: rating, Window = 1yr ● Source: Ratings table ● They are all aggregations

- 18. Feature Serving for inference What is the value of these feature aggregates now?
- 19. Real-time features • Event log + Event Stream = Realtime – Features • DB Snapshots + Change data = Realtime-features
- 20. Feature Serving • Latency • Optimized for point queries • Freshness vs latency • Service Events and DB Mutations • Batch correction
- 21. Feature Computation for training What are the exact feature values at the points-of-interest in history?

- 23. Model Server Architecture Feature Declaration Streaming Updates Batch partial aggregates Feature Store Feature Backfills Model Training Model Feature Client Labeling Application Server
- 24. Aggregation Math
- 25. Aggregations – SUM • Commutative: a + b = b + a • Associative: (a + b) + c = a + (b + c) • Reversible: (a + b) – a = b • Abelian Group
- 26. Aggregations – AVG • One not-so-clever trick • Operate on “Intermediate Representation” / IR • Factors into (sum, count) • Finalized by a division: (sum/count)
- 27. Aggregations • Constant memory / Bounded IR • Two classes of aggregations • Sum, Avg, Count etc., • Reversible / Abelian Groups • Min, Max, Approx Unique, most sketches etc., • Non-Reversible / Commutative Monoids / Non-Groups
- 28. Incremental Windowing – with reversibility 0 1 .. .. 0 1 0 .. Visits – check-in stream of a user 1 4 6 8 9 8 7 In the last year -1 +0
- 29. 2 2 2 Incremental Windowing – with reversibility 1 3 Max rating – Ratings table – grouped by user 3 2 4 4 4 1 0 1 0 1 1 1 4 2 3 3 1 0 1 3 1 2 2 2 2 4
- 30. Windowing – w/o reversibility • Time: O(N^2) vs O(NLogN) • Space: N vs 2N memory Groups Non-Groups Un-Windowed No-Reversal No-Reversal Windowed Reversal Tree
- 31. Windowing – w/o reversibility • Tiling problem • Tile([left, right]) => Tile([left, split_point]) + Tile([split_point, right]) • Split_point => right && (MAX_INT << msb(left ^ right)) • Tiles are the binary representation of (right – split_point) and (split_point - left) • Less hand-waving in the paper
- 32. Reversibility - Unpacking Change data • Deletion is a reversal • Update is a delete followed by an insert • Example: • Sudden heat wave forecast at 7 pm.

- 34. Feature Backfill • Time-series join with aggregations • Left :: Query Log :: [(Entity Key, timestamp)] • Right :: Raw Data :: [(Entity Key, timestamp, unaggregated)] • Output :: Feature Data :: [(Entity Key, timestamp, aggregated)] • Aggregation and join is fused • Raw data >> query log

- 37. Feature Backfill – Nuances • Time Skew • Event time vs ingestion time • Many sources of raw data at once • Un-skewed can be faster • More in paper
