Serverless machine learning operations

Stepan Pushkarev

Any startup has to have a clear go-to-market strategy from the beginning. Similarly, any data science project has to have a go-to-production strategy from its first days, so it could go beyond proof-of-concept. Machine learning and artificial intelligence in production would result in hundreds of training pipelines and machine learning models that are continuously revised by teams of data scientists and seamlessly connected with web applications for tenants and users. In this demo-based talk we will walk through the best practices for simplifying machine learning operations across the enterprise and providing a serverless abstraction for data scientists and data engineers, so they could train, deploy and monitor machine learning models faster and with better quality.

Data & ML projects bring many new complexities beyond the traditional software development lifecycle. Unlike software projects, after they were successfully delivered and deployed, they cannot be abandoned but must be continuously monitored if model performance still satisfies all requirements. We can always get new data with new statistical characteristics that can break our pipelines or influence model performance.

MLflow with R

Databricks

This talk will present R as a programming language suited for solving data analysis and modeling problems, MLflow as an open source project to help organizations manage their machine learning lifecycle and the intersection of both by adding support for R in MLflow. It will be highly interactive and touch on some of the technical implementation choices taken while making R available in MLflow. It will also demonstrate using MLflow tracking, projects, and models directly from R as well as reusing R models in MLflow to interoperate with other programming languages and technologies.

MLFlow: Platform for Complete Machine Learning Lifecycle

Databricks

Description Data Science and ML development bring many new complexities beyond the traditional software development lifecycle. Unlike in traditional software development, ML developers want to try multiple algorithms, tools, and parameters to get the best results, and they need to track this information to reproduce work. MLflow addresses some of these challenges during an ML model development cycle. Abstract ML development brings many new complexities beyond the traditional software development lifecycle. Unlike in traditional software development, ML developers want to try multiple algorithms, tools, and parameters to get the best results, and they need to track this information to reproduce work. In addition, developers need to use many distinct systems to productionize models. To address these problems, many companies are building custom “ML platforms” that automate this lifecycle, but even these platforms are limited to a few supported algorithms and to each company’s internal infrastructure. In this session, we introduce MLflow, a new open source project from Databricks that aims to design an open ML platform where organizations can use any ML library and development tool of their choice to reliably build and share ML applications. MLflow introduces simple abstractions to package reproducible projects, track results, and encapsulate models that can be used with many existing tools, accelerating the ML lifecycle for organizations of any size. With a short demo, you see a complete ML model life-cycle example, you will walk away with: MLflow concepts and abstractions for models, experiments, and projects How to get started with MLFlow Using tracking Python APIs during model training Using MLflow UI to visually compare and contrast experimental runs with different tuning parameters and evaluate metrics

AllThingsOpen 2018 - Deployment Design Patterns (Dan Zaratsian)

dtz001

While the adoption of machine learning and deep learning techniques continue to grow, many organizations find it difficult to actually deploy these sophisticated models into production. It is common to see data scientists build powerful models, yet these models are not deployed because of the complexity of the technology used or lack of understanding related to the process of pushing these models into production. As part of this talk, I will review several deployment design patterns for both real-time and batch use cases. I’ll show how these models can be deployed as scalable, distributed deployments within the cloud, scaled across hadoop clusters, as APIs, and deployed within streaming analytics pipelines. I will also touch on topics related to security, end-to-end governance, pitfalls, challenges, and useful tools across a variety of platforms. This presentation will involve demos and sample code for the the deployment design patterns.

Moving a Fraud-Fighting Random Forest from scikit-learn to Spark with MLlib, ...

Databricks

This talk describes migrating a large random forest classifier from scikit-learn to Spark's MLlib. We cut training time from 2 days to 2 hours, reduced failed runs, and track experiments better with MLflow. Kount provides certainty in digital interactions like online credit card transactions. One of our scores uses a random forest classifier with 250 trees and 100,000 nodes per tree. We used scikit-learn to train using 60 million samples that each contained over 150 features. The in-memory requirements exceeded 750 GB, took 2 days, and were not robust to disruption in our database or training execution. To migrate workflow to Spark, we built a 6-node cluster with HDFS. This provides 1.35 TB of RAM and 484 cores. Using MLlib and parallelization, the training time for our random forests are now less than 2 hours. Training data stays in our production environment, which used to require a deploy cycle to move locally-developed code onto our training server. The new implementation uses Jupyter notebooks for remote development with server-side execution. MLflow tracks all input parameters, code, and git revision number, while the performance and model itself are retained as experiment artifacts. The new workflow is robust to service disruption. Our training pipeline begins by pulling from a Vertica database. Originally, this single connection took over 8 hours to complete with any problem causing a restart. Using sqoop and multiple connections, we pull the data in 45 minutes. The old technique used volatile storage and required the data for each experiment. Now, we pull the data from Vertica one time and then reload much faster from HDFS. While a significant undertaking, moving to the Spark ecosystem converted an ad hoc and hands-on training process into a fully repeatable pipeline that meets regulatory and business goals for traceability and speed.

Driverless AI - Intro + Interactive Hands-on Lab

Sri Ambati

Enjoy the webinar recording here: https://youtu.be/Lll1qwQJKVw. Driverless AI speeds up data science workflows by automating feature engineering, model tuning, ensembling, and model deployment. In this presentation, Arno Candel (CTO, H2O.ai), gives a quick overview and guide attendees through an interactive hands-on lab using Qwiklabs. Driverless AI turns Kaggle-winning recipes into production-ready code and is specifically designed to avoid common mistakes such as under or overfitting, data leakage or improper model validation. Avoiding these pitfalls alone can save weeks or more for each model, and is necessary to achieve high modeling accuracy. With Driverless AI, everyone can now train and deploy modeling pipelines with just a few clicks from the GUI. Advanced users can use the client/server API through a variety of languages such as Python, Java, C++, go, C# and many more. To speed up training, Driverless AI uses highly optimized C++/CUDA algorithms to take full advantage of the latest compute hardware. For example, Driverless AI runs orders of magnitudes faster on the latest Nvidia GPU supercomputers on Intel and IBM platforms, both in the cloud or on-premise. There are two more product innovations in Driverless AI: statistically rigorous automatic data visualization and interactive model interpretation with reason codes and explanations in plain English. Both help data scientists and analysts to quickly validate the data and models.

Version Control in AI/Machine Learning by Datmo

Nicholas Walsh

Starting with outlining the history of conventional version control before diving into explaining QoDs (Quantitative Oriented Developers) and the unique problems their ML systems pose from an operations perspective (MLOps). With the only status quo solutions being proprietary in-house pipelines (exclusive to Uber, Google, Facebook) and manual tracking/fragile "glue" code for everyone else. Datmo works to solve this issue by empowering QoDs in two ways: making MLOps manageable and simple (rather than completely abstracted away) as well as reducing the amount of glue code so to ensure more robust pipelines.

Enabling Data centric Teams

Data Con LA

Data Con LA 2020 Description Coming from a grand belief of data democratization, I believe that in order for any team to be successful collaborators, it has to be data centric and data should be accessible to all. *To ensure that your non software or software engineering centric team has maximum efficiency, data should be visible, data lake should be accessible. *Form a database for analytics summaries, talk about the different technologies(SQL, NoSQL) cost of deployment, need, team driven structure. Build an API for this database for external/inter team crosstalk. *Build analytics and visual layer on top of it. Flask/Django/Node, etc.., to enable the team to have high visibility in their analysis, and to ensure a higher turnaround of data. *Talk about an easy way of enabling the team to run code, could be local/cloud, JupyterHub is a great way of doing so, talk about the tremendous value added in that and the potential it enables *Talk about the common tools user for version control/CICD/Coding technologies, etc.. *Finally summarize the value of the mixture of all these tools and technologies in order to ensure the maximum efficiency.

Build Answer-generating Apps that Users Love: Development best practices for ...

TIBCO Jaspersoft

More and more employees (not just data analysts or C-level execs) are expected to make data-driven decisions, yet only 20–25% of workers have access to business intelligence (BI) products. And when asked, end users don’t want to use a “BI tool”—another interface to learn, another login—they want easily accessible answers. Instead of offering a standalone dashboard, the new trend is to embed analytics into applications that are already used every day. This workshop series features a brand new demo application—created by TIBCO Jaspersoft and projekt202—that illustrates and teaches you how to create answer-generating applications. Over four webinars, we will show you to the what and why of data-as-a-feature applications and how you can build your own. Data-as-a-Feature webinar sessions: - Build answer-generating apps that users love: Learn best practices for making data valuable to your application users - Getting started: How to set up your data-as-a-feature project - Your data in your app: Best practices for embedding interactive reports and visualizations in your app - Managing the experience + ad hoc reporting: Handling security, multi-tenancy, and self-service reporting for your data-as-a-feature app

Building a healthy data ecosystem around Kafka and Hadoop: Lessons learned at...

Yael Garten

2017 StrataHadoop SJC conference talk. https://conferences.oreilly.com/strata/strata-ca/public/schedule/detail/56047 Description: So, you finally have a data ecosystem with Kafka and Hadoop both deployed and operating correctly at scale. Congratulations. Are you done? Far from it. As the birthplace of Kafka and an early adopter of Hadoop, LinkedIn has 13 years of combined experience using Kafka and Hadoop at scale to run a data-driven company. Both Kafka and Hadoop are flexible, scalable infrastructure pieces, but using these technologies without a clear idea of what the higher-level data ecosystem should be is perilous. Shirshanka Das and Yael Garten share best practices around data models and formats, choosing the right level of granularity of Kafka topics and Hadoop tables, and moving data efficiently and correctly between Kafka and Hadoop and explore a data abstraction layer, Dali, that can help you to process data seamlessly across Kafka and Hadoop. Beyond pure technology, Shirshanka and Yael outline the three components of a great data culture and ecosystem and explain how to create maintainable data contracts between data producers and data consumers (like data scientists and data analysts) and how to standardize data effectively in a growing organization to enable (and not slow down) innovation and agility. They then look to the future, envisioning a world where you can successfully deploy a data abstraction of views on Hadoop data, like a data API as a protective and enabling shield. Along the way, Shirshanka and Yael discuss observations on how to enable teams to be good data citizens in producing, consuming, and owning datasets and offer an overview of LinkedIn’s governance model: the tools, process and teams that ensure that its data ecosystem can handle change and sustain #DataScienceHappiness.

Algorithmic optimizations for Dynamic Levelwise PageRank (from STICD) : SHORT...

Subhajit Sahu

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...

Subhajit Sahu

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.
