Unexpected Challenges in Large Scale Machine Learning by Charles ParkerBigMine
Talk by Charles Parker (BigML) at BigMine12 at KDD12.
In machine learning, scale adds complexity. The most obvious consequence of scale is that data takes longer to process. At certain points, however, scale makes trivial operations costly, thus forcing us to re-evaluate algorithms in light of the complexity of those operations. Here, we will discuss one important way a general large scale machine learning setting may differ from the standard supervised classification setting and show some the results of some preliminary experiments highlighting this difference. The results suggest that there is potential for significant improvement beyond obvious solutions.
Implementation of Big Data infrastructure and technology can be seen in various industries like banking, retail, insurance, healthcare, media, etc. Big Data management functions like storage, sorting, processing and analysis for such colossal volumes cannot be handled by the existing database systems or technologies. Frameworks come into picture in such scenarios. Frameworks are nothing but toolsets that offer innovative, cost-effective solutions to the problems posed by Big Data processing and helps in providing insights, incorporating metadata and aids decision making aligned to the business needs.

Big data - what, why, where, when and howbobosenthil
The document discusses big data, including what it is, its characteristics, and architectural frameworks for managing it. Big data is defined as data that exceeds the processing capacity of conventional database systems due to its large size, speed of creation, and unstructured nature. The architecture for managing big data is demonstrated through Hadoop technology, which uses a MapReduce framework and open source ecosystem to process data across multiple nodes in parallel.
Big data is characterized by 3Vs - volume, velocity, and variety. Hadoop is a framework for distributed processing of large datasets across clusters of computers. It provides HDFS for storage, MapReduce for batch processing, and YARN for resource management. Additional tools like Spark, Mahout, and Zeppelin can be used for real-time processing, machine learning, and data visualization respectively on Hadoop. Benefits of Hadoop include ease of scaling to large data, high performance via parallel processing, reliability through data protection and failover.
Bigdata and data warehousing can work in synergy by applying the structure of data warehousing to the large and unstructured datasets of bigdata. While data warehousing focuses on modeling data, co-locating related information, and optimizing queries, bigdata is better suited to analyzing unstructured data at scale through distributed systems without an upfront model. The two approaches complement each other by bringing structure to bigdata through modeling and applying bigdata's ability to analyze unstructured data at massive scale.

The presentation also covers challenges of big data analytics, existing case studies using tools like SAP Hana and Revolution Analytics, and concerns around privacy with large-scale data analysis.
Big data analytics is the use of advanced analytic techniques against very large, diverse data sets that include different types such as structured/unstructured and streaming/batch, and different sizes from terabytes to zettabytes. Big data is a term applied to data sets whose size or type is beyond the ability of traditional relational databases to capture, manage, and process the data with low-latency. And it has one or more of the following characteristics – high volume, high velocity, or high variety. Big data comes from sensors, devices, video/audio, networks, log files, transactional applications, web, and social media - much of it generated in real time and in a very large scale.
Analyzing big data allows analysts, researchers, and business users to make better and faster decisions using data that was previously inaccessible or unusable. Using advanced analytics techniques such as text analytics, machine learning, predictive analytics, data mining, statistics, and natural language processing, businesses can analyze previously untapped data sources independent or together with their existing enterprise data to gain new insights resulting in significantly better and faster decisions.

We will use an example use case to show how data is being generated, ingested, and how each component in the stack can be replaced.
Big Data in the Cloud: Enabling the Fourth Paradigm by Matching SMEs with Dat...Alexandru Iosup
Data are pouring in, and defining and providing data-processing services at massive scale, in short, Big Data services, could significantly improve the revenue of Europe's Small and Medium Enterprises (SMEs). A paradigm shift is about occur, one in which data processing becomes a basic life utility, for both SMEs and the European people. Although the burgeoning datacenter industry, of which the Netherlands is a top player in Europe, is promising to enable Big Data services, the architectures and even infrastructure for these services are still lagging behind in performance, efficiency, and sophistication, and are built as monoliths reminding us of traditional data silos. Can we remove the performance and efficiency limitations of the current Big Data ecosystems, that is, of the complex stacks of middleware that are currently in use, for Big Data services? In this talk, I will present several use cases (workloads) of Big Data services for time-stamped [2,3] and graph data [4], evaluate or benchmark the performance of several Big Data stacks [3,4] for these use-cases, and present a path (and promising early results) to providing a generic, data-agnostic, non-monolithic Big Data architecture that can efficiently and elastically use datacenter resources via cloud computing interfaces [1,5].

The document discusses using machine learning for efficient attack detection in IoT devices without feature engineering. It proposes a feature-engineering-less machine learning (FEL-ML) process that uses raw packet byte streams as input instead of engineered features. This approach is lighter weight and faster than traditional methods. The FEL-ML model is trained directly on unprocessed packet data to perform malware detection on resource-constrained IoT devices. Prior research that used engineered features or complex deep learning models are not suitable for IoT due to limitations of memory and processing power. The proposed FEL-ML approach aims to enable effective network traffic security for IoT using minimal resources.
EFFICIENT ATTACK DETECTION IN IOT DEVICES USING FEATURE ENGINEERING-LESS MACH...ijcsit
Through the generalization of deep learning, the research community has addressed critical challenges in
the network security domain, like malware identification and anomaly detection. However, they have yet to
discuss deploying them on Internet of Things (IoT) devices for day-to-day operations. IoT devices are often
limited in memory and processing power, rendering the compute-intensive deep learning environment
unusable. This research proposes a way to overcome this barrier by bypassing feature engineering in the
deep learning pipeline and using raw packet data as input. We introduce a feature- engineering-less
machine learning (ML) process to perform malware detection on IoT devices. Our proposed model,”
Feature engineering-less ML (FEL-ML),” is a lighter-weight detection algorithm that expends no extra
computations on “engineered” features. It effectively accelerates the low-powered IoT edge. It is trained
on unprocessed byte-streams of packets. Aside from providing better results, it is quicker than traditional
feature-based methods. FEL-ML facilitates resource-sensitive network traffic security with the added
benefit of eliminating the significant investment by subject matter experts in feature engineering.

It describes how IBM's Watson uses Hadoop to distribute its workload and load information into memory from sources like 200 million pages of text, CRM data, POS data, and social media to provide distilled insights. The document provides two use case examples of how energy companies and global media firms could use big data analytics to analyze weather data and identify unauthorized streaming content.
How to Crunch Petabytes with Hadoop and Big Data Using InfoSphere BigInsights...DATAVERSITY
Do you wonder how to process huge amounts of data in short amount of time? If yes, this session is for you! You will learn why Apache Hadoop and Streams is the core framework that enables storing, managing and analyzing of vast amounts of data. You will learn the idea behind Hadoop's famous map-reduce algorithm and why it is at the heart of solutions that process massive amounts of data with flexible workloads and software based scaling. We explore how to go beyond Hadoop with both real-time and batch analytics, usability, and manageability. For practical examples, we will use IBM InfoSphere BigInsights and Streams, which build on top of open source tooling when going beyond basics and scaling up and out is needed.

machine
learning
algorithms
distributed
2.
Update
locally
l Online
training
without
communication
with
others
3.
Mix
only
models
l Small
communication
cost,
low
latency,
good
performance
l Advantage
compared
to
costly
Shuffle
in
MapReduce
4.
Analyze
locally
l Each
server
has
mixed
model
and
need
not
to
communicate
l Low
latency
for
making
predictions
5.
Everything
in-‐memory
l Process
