MLconf Atlanta

Friday, September 19, 2014 from 8:00 AM to 6:00 PM (EDT) More Information → Register

Join us for an exciting event on September 19th, a block away of Georgia Tech at the Academy of Medicine for the first Atlanta-based MLconf. This year MLconf will focus on ML platforms, tools and algorithms. We'll host a speaker from Facebook whom will give us an overview of how machine learning shapes the biggest social network. We are very happy to have speakers from emerging platforms like Revolution Analytics one of the top players in industrial strength parallel R, SkyTree with their super fast and scalable machine learning server, Context Relevant with their scalable platform that finds structure in the data in record time, and 0xdata’s will present their open source platform and the new deep learning toolbox. Come and find out more about Systap’s graph analytics and machine learning platform on GPUs and Finally if you play in the traditional RDBMS field ORACLE will tell you how to do machine learning. If you are in he NOSQL arena, Cloudera will present the current trends. Professor Manos Antonakis will explain why machine learning alone cannot solve problems, without some domain expertise through his experience in internet security. Professor Amy Langville, the guru of ranking and also the author of “Who is #1”, “Google’s, Page rank and Beyond” will tell us how to rank all kinds of data, from sport teams to movies. If you want to find out how Netflix and Meetup, do their recommendations, you will be surprised by the difference on the constraints and data availability they have.

Evan Estola - Data Scientist, Meetup.com

Abstract: Beyond Collaborative Filtering: using Machine Learning to power recommendations at Meetup
Collaborative filtering and other common recommendation algorithms are a powerful technique for some scenarios. I will cover how to design a recommendation system from the ground up using an ensemble classifier and supervised learning to avoid some of the pitfalls of collaborative filtering. From sampling to deployment, we’ve had to invent our approach with few non-academic and non-toy examples to follow. At Meetup we’re all about sharing information and empowering communities, so I’ll present the details of our model as well as some of the new features we are still developing.

Parikshit Ram - Senior Machine Learning Scientist, Skytree

Abstract: Max-kernel search: How to search for just about anything?

Nearest neighbor search is a well studied and widely used task in computer science and is quite pervasive in everyday applications. While search is not synonymous with learning, search is a crucial tool for the most nonparametric form of learning. Nearest neighbor search can directly be used for all kinds of learning tasks — classification, regression, density estimation, outlier detection. Search is also the computational bottleneck in various other learning tasks such as clustering and dimensionality reduction. Key to nearest neighbor search is the notion of "near"-ness or similarity. Mercer kernels form a class of general nonlinear similarity functions and are widely used in machine learning. They can define a notion of similarity between pairs of objects of any arbitrary type and have been successfully applied to a wide variety of object types — fixed-length data, images, text, time series, graphs. I will present a technique to do nearest neighbor search with this class of similarity functions provably efficiently, hence facilitating faster learning for larger data.

Manos Antonakakis - Assistant Professor of Computer Systems and Software, Georgia Tech

Abstract: So, you think you can model Internet abuse with machine learning?

Abuse in the Internet is an every day problem. Illicit actors are victimizing people, which result to a variety of significant problems --- i.e., from losing your private information to have your recourses being used in other criminal activities. The common denominator behind the Internet abuse is a network of infected machines (a.k.a. botnet) under the control of the criminal entity (a.k.a. botmaster). Needless to say, the detection of such "botnet communications" is in the hurt of the security problem that a large organization faces every day. Detection methods based on static methods are doomed fail, simply because they will always be behind the threat. Thus, the community is in great need of scalable abuse detection solutions.

Unsurprisingly, such newly proposed solutions are often based on machine learning. With this talk I will argue that a fancy machine-learning algorithm (and derived pretty graph pictures) "operationally" will simply not "cut-it". This is true especially in the case where what you are trying to solve is not your company's marketing problem, rather the security problem your network and security operation center is facing every day. The role of domain knowledge and constant counter intelligence of the malicious actors is fundamental to properly craft generic detection and attribution solutions able to catch up with the constantly changing malicious methodologies, while at the same time you minimize the false and missed detections.

Danai Koutra - CMU/Technicolor Researcher, Carnegie Mellon University

Abstract:
Networks naturally capture a host of interactions in the real world spanning from friendships to brain activity. But, given a massive graph, like the Facebook social graph, what can be said about its structure? Which are its most important structures? How does it compare to other networks like Twitter? This talk will focus on my work developing scalable algorithms and models that help us to make sense of large graphs via pattern discovery and similarity analysis.

I will begin by presenting VoG, an approach that efficiently summarizes large graphs by finding their most interesting and semantically meaningful structures. Starting from a clutter of millions of nodes and edges, such as the Enron who-mails-whom graph, our Minimum Description Length based algorithm, disentangles the complex graph connectivity and spotlights the structures that ‘best’ describe the graph.

Then, for similarity analysis at the graph level, I will introduce the problems of graph comparison and graph alignment. I will conclude by showing how to apply my methods to temporal anomaly detection, brain graph clustering, deanonymization of bipartite (e.g., user-group membership) and unipartite graphs, and more.

Abstract: PGX: An In-Memory, Parallel Graph Analytic and Query Engine


Brief Description:
In-memory (and distributed) graph analytic engine that is tightly coupled with a relational database.


Abstract:
We present a graph processing system in which a graph database is tightly integrated with a graph analytic engine. Our graph database, based on existing NoSQL and relational databases, provides scalable management of graph data for transactional workloads. Our graph analytic engine, on the other hand, enables rapid execution of analytic workloads. We first introduce PGX, our in-memory graph analytic engine which initially loads up the graph data from the database and periodically synchronizes afterward. The parallel execution engine of PGX is very efficient - e.g. counting triangles in billion-edge graphs in 2 minutes. The users can also submit their custom graph algorithms written in a domain-specific language; PGX automatically parallelizes them for execution. Then we introduce PGX.DIST, our distributed graph analytic engine. We show that PGX.DIST is up to orders of magnitude faster than the state-of-art graph analytic engine. The DSL compiler can help running the same algorithm on both PGX and PGX.DIST, transparently.
* Graph database tightly integrated with graph analytic engine
* Fast, parallel in-memory graph analytic engine
* Distributed graph analytic engine
* Use of Domain-Specific Language for graph analytics.
