Why Machine Learning Algorithms Fall Short (And What You Can Do About It): Many think that machine learning is all about the algorithms. Want a self-learning system? Get your data, start coding or hire a PhD that will build you a model that will stand the test of time. Of course we know that this is not enough. Models degrade over time, algorithms that work great on yesterday’s data may not be the best option, new data sources and types are made available. In short, your self-learning system may not be learning anything at all. In this session, we will examine how to overcome challenges in creating self-learning systems that perform better and are built to stand the test of time. We will show how to apply mathematical optimization algorithms that often prove superior to local optimization methods favored by typical machine learning applications and discuss why these methods can crate better results. We will also examine the role of smart automation in the context of machine learning and how smart automation can create self-learning systems that are built to last.

Machine Learning in Production
The era of big data generation is upon us. Devices ranging from sensors to robots and sophisticated applications are generating increasing amounts of rich data (time series, text, images, sound, video, etc.). For such data to benefit a business’s bottom line, insights must be extracted, a process that increasingly requires machine learning (ML) and deep learning (DL) approaches deployed in production applications use cases.
Production ML is complicated by several challenges, including the need for two very distinct skill sets (operations and data science) to collaborate, the inherent complexity and uniqueness of ML itself, when compared to other apps, and the varied array of analytic engines that need to be combined for a practical deployment, often across physically distributed infrastructure. Nisha Talagala shares solutions and techniques for effectively managing machine learning and deep learning in production with popular analytic engines such as Apache Spark, TensorFlow, and Apache Flink.

We can make a data mining to get the prediction about the future data, which is mined from an old data especially Big data using a machine learning algorithms based on two clusters. One is the intrinsic for managing the file system of Big data, which is called Hadoop. The other is essentially to make fast analysis of Big data which is called Apache Spark. In order to achieve this purpose we will use R based on Rstudio or Scala based on Zeppelin.
A Maturing Role of Workflows in the Presence of Heterogenous Computing Archit...Ilkay Altintas, Ph.D.
cientific workflows are used by many scientific communities to capture, automate and standardize computational and data practices in science. Workflow-based automation is often achieved through a craft that combines people, process, computational and Big Data platforms, application-specific purpose and programmability, leading to provenance-aware archival and publications of the results. This talk summarizes varying and changing requirements for distributed workflows influenced by Big Data and heterogeneous computing architectures and present a methodology for workflow-driven science based on these maturing requirements.

From Pipelines to Refineries: Scaling Big Data ApplicationsDatabricks
Big data tools are challenging to combine into a larger application: ironically, big data applications themselves do not tend to scale very well. These issues of integration and data management are only magnified by increasingly large volumes of data.
Apache Spark provides strong building blocks for batch processes, streams and ad-hoc interactive analysis. However, users face challenges when putting together a single coherent pipeline that could involve hundreds of transformation steps, especially when confronted by the need of rapid iterations.
This talk explores these issues through the lens of functional programming. It presents an experimental framework that provides full-pipeline guarantees by introducing more laziness to Apache Spark. This framework allows transformations to be seamlessly composed and alleviates common issues, thanks to whole program checks, auto-caching, and aggressive computation parallelization and reuse.
Tiny Batches, in the wine: Shiny New Bits in Spark StreamingPaco Nathan
London Spark Meetup 2014-11-11 @Skimlinks
http://www.meetup.com/Spark-London/events/217362972/
To paraphrase the immortal crooner Don Ho: "Tiny Batches, in the wine, make me happy, make me feel fine." http://youtu.be/mlCiDEXuxxA
Apache Spark provides support for streaming use cases, such as real-time analytics on log files, by leveraging a model called discretized streams (D-Streams). These "micro batch" computations operated on small time intervals, generally from 500 milliseconds up. One major innovation of Spark Streaming is that it leverages a unified engine. In other words, the same business logic can be used across multiple uses cases: streaming, but also interactive, iterative, machine learning, etc.
This talk will compare case studies for production deployments of Spark Streaming, emerging design patterns for integration with popular complementary OSS frameworks, plus some of the more advanced features such as approximation algorithms, and take a look at what's ahead — including the new Python support for Spark Streaming that will be in the upcoming 1.2 release.
Also, let's chat a bit about the new Databricks + O'Reilly developer certification for Apache Spark…
In the past, emerging technologies took years to mature. In the case of big data, while effective tools are still emerging, the analytics requirements are changing rapidly resulting in businesses to either make it or be left behind
Python + MPP Database = Large Scale AI/ML Projects in Production FasterPaige_Roberts
ODSC East virtual presentation - The best machine learning, and advanced analytics projects are often stopped when it comes time to move into large scale production, preventing them from ever impacting the business in a meaningful way. Hundreds of hours of work may never get put to use.
Python is rapidly becoming the language of choice for scientists and researchers of many types to build, test, train and score models. But when data science models need to go into production, challenges of performance and scale can be a huge roadblock.
By combining a Python application with an underlying massively parallel (MPP) database, Python users can achieve a simplified path to production. An MPP database also allows you to do data preparation and data analysis at far greater speeds, accelerating development and testing as well as production performance. It also allows greater numbers of concurrent jobs to run, while also continuously loading data for IoT or other streaming use cases.
Analyze data in the database where it sits, rather than first moving it to another framework, then analyzing it, then moving the results, taking multiple performance hits from both CPU and IO for every move and transformation.
In this talk, you will learn about combination architectures that can get your work into production, shorten development time, and provide the performance and scale advantages of an MPP database with the convenience and power of Python. Use case examples use the open source Vertica-Python project created by Uber with contributions from Twitter, Palantir, Etsy, Vertica, Kayak and Gooddata.
When data size grows in terms of sample count, feature count and model parameter count, things go crazy. The slideshow presents an overview of what to expect and how to handle them.
On a business level, everyone wants to get hold of the business value and other organizational advantages that big data has to offer. Analytics has arisen as the primitive path to business value from big data. Hadoop is not just a storage platform for big data; it’s also a computational and processing platform for business analytics. Hadoop is, however, unsuccessful in fulfilling business requirements when it comes to live data streaming. The initial architecture of Apache Hadoop did not solve the problem of live stream data mining. In summary, the traditional approach of big data being co-relational to Hadoop is false; focus needs to be given on business value as well. Data Warehousing, Hadoop and stream processing complement each other very well. In this paper, we have tried reviewing a few frameworks and products
which use real time data streaming by providing modifications to Hadoop.

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.

4. Doing something useful with data
●Often, “doing something useful” = Placing a schema over it
and using SQL to answer questions like
●“of the gazillion users who made it to the third page in
our registration process, how many are over 25?”
●The field of how to structure a data warehouse and
organize information to make answering these kinds of
questions easy is a rich one.
5. A new superpower !
●When people say that we live in an age of “big data,” they
mean that we have tools for collecting, storing, and
processing information at a scale previously unheard of.
●There is a gap between having access to these tools and all
this data, and doing something useful with it.
6. Doing extra useful things
●Requirements :
a- Flexible programming model
b- Rich functionality in machine learning and statistics
●Existing Tools :
R, Python (PyData stack) and Octave
Pros : Little effort, easy to use
Cons : Viable only to small data sets, too complex to
redesign to be suitable for working over clusters of
computers.
7. Why is it difficult ?
●Some algorithms (like machine learning algos) would have
wide data dependencies.
• Data are partitioned across nodes.
• Network transfer is much sloooower than memory
accesses.
●What about the probability of failures ?
●Summary : We need a programming paradigm that is
sensitive to the c/c of the underlying system and that
encourages good choices and make it easy to write parallel
code.
8. High performance Computing
●Use Case : processing a large file full of DNA sequencing
reads in parallel
●1- Manually split the file into smaller files
●2- Submitting a job for each file split to the scheduler
●3- Continuous jobs monitoring to resubmit any failed jobs
●All to all operations like sorting the full data would require
streaming through one node or to go and use MPI.
●Relatively low level of abstraction and difficulty of use in
addition to the high cost.
9. The 3 truths about data science
●Successful data preprocessing is a must for successful
analysis.
–Large data sets requires special treatment
–Feature engineering should be given more time than the
time spent on the algorithms stuff. (A model for fraud
detection can use IP location info, login times, click logs)
–How would you convert features into vectors suitable for ML
algorithms.
10. The 3 truths about data science
●Iteration is the key.
–Famous optimization techniques like Gradient Descent
requires repeated scans over the input until convergence
–You can't get it right from the first time.

11. Analytics between lab and factory
A framework that makes modeling easy
but is also a good fit for production systems is a huge
win.
12. Apache Spark In Points
●Spark continues from what Hadoop Shines at (Linear
Scalability , Fault Tolerance)
●Spark supports DAG (Direct Acyclic Graph of operators)
●Complements its capabilities with rich set of
transformations.
●In-memory processing. (Suitable for iterations)
13. Apache Spark In Points
●The most important bottleneck that Spark addresses is
analyst productivity. (R, HDFS, MR, .. etc)
●Spark is better at being an operational system than most
exploratory systems and better for data exploration than
the technologies commonly used in operational systems.
●Standing on top of JVM – Good integration with Hadoop
ecosystem
14. Spark From the other side !
●Still young compared to MapReduce
●Its main components needs a lot of work to be mature
enough (stream processing, SQL, machine learning, and
graph processing)
–MLlib’s pipelines and transformer API model is in progress
–Its statistics and modeling functionality comes nowhere near that of
single machine languages like R
–Its SQL functionality is rich, but still lags far behind that of Hive.
15. Spark Programming Model
●It starts with a dataset or a few residing in a distributed
persistent storage (like HDFS)
●Writing a Spark program typically consists of a few related
steps:
–Defining a set of transformations on input data sets.
–Invoking actions that output the transformed data sets to persistent
storage or return results to the driver’s local memory.
–Running local computations that operate on the results computed in a
distributed fashion. These can help you decide what transformations
and actions to undertake next.
16. Why should you consider Scala ?
●Spark has already different wrappers (Java, python)
●It reduces performance overhead. (Running your different
language of top of JVM)
●It gives you access to the latest and greatest.
●It will help you understand the Spark philosophy.
–If you know how to use Spark in Scala, even if you primarily
use it from other languages, you’ll have a better
understanding of the system and will be in a better position
to “think in Spark.”
17. If you are immune to boredom,
there is literally nothing you cannot
accomplish.
—David Foster Wallace
18. Data Science's First Step
●Data cleansing is the first step in any data science project.
●Many clever analyses have been undone because the data
analyzed had fundamental quality problems or bias problem.
●It is a dull work that you have to do before you can get to
the really cool machine learning algorithm that you’ve been
dying to apply to a new problem.
19. Our First Real Problem !
●Name : Record Linkage
●Description :
–we have a large collection of records from one or more
source systems
–it is likely that some of the records refer to the same
underlying entity, such as a customer, a patient.
–Each of the entities has a number of attributes, such as a
name or address
20. The Challenge
●Challenge :
–The values of these attributes aren’t perfect
–Values might have different formatting, or typos, or missing
information.
–It is easy for a human to understand and identify at a
glance, but is difficult for a computer to learn.
21. Steps we are going to take
●Bringing Data from the Cluster to the Client
●Shipping Code from the Client to the Cluster
●Structuring Data with Tuples and Case Classes
●Getting some numbers regarding our data.
