PedroDomingoTitle: “Sum-Product Networks: The Next Generation of Deep Models”

Speaker: Pedro Domingo (University of Washington)

Date/Time: April 19, 2017, @ 12n (lunch served at 11:30am)

Location: Engineered Biosystems Building (EBB), CHOA Room

Abstract: The two main types of deep learning are function approximation and probability estimation. Function approximators like convolutional neural networks are robust and allow for real-time inference, but are very inflexible, requiring fixed inputs and outputs and detailed supervision. Probability estimators like deep Boltzmann machines allow arbitrary inputs and outputs and require no supervision, but are not robust and do not allow real-time inference.
Both are very opaque. Sum-product networks (SPNs) are a new class of deep models that are suitable for both function approximation and probability estimation. SPNs allow for real-time inference, are robust and comprehensible, and are highly flexible, with any choice of inputs and outputs and any amount of supervision. I will present generative and discriminative algorithms for learning SPN weights, and an algorithm for learning SPN structure. SPNs have achieved impressive results in a wide variety of domains, including object recognition, image completion, activity recognition, language modeling, collaborative filtering, and click prediction, and are arguably the most powerful class of deep models available today. (Joint work with Abe Friesen, Rob Gens, Mathias Niepert and Hoifung Poon.)

Welcome The Agency, the undergraduate AI/ML club at Georgia Tech

agencyblurbformlgt_pdf__page_2_of_2_

The Agency is an undergraduate AI/ML club at Georgia Tech. Here is a short introduction to The Agency, from the members of this club.

We are a hub for connecting undergraduate students with the machine learning community at Tech. Every week, we present talks on machine learning/artificial intelligence. These range from undergraduates lecturing on interesting concepts in the field to professors/graduate students presenting their research.

Beyond our weekly lectures, we give people the resources to do machine learning research. For instance, we organize larger events, such as our recent workshop on TensorFlow, and offer dedicated computing resources for undergraduates to train learning models. We also host a deep learning paper reading group that meets every two weeks.agencyblurbformlgt_pdf__page_2_of_2_

Furthermore, we also work on projects such as Buzzmobile, an autonomous vehicle modeled after the Rambling Wreck. Buzzmobile has a purely reactive control architecture, built entirely in ROSpy. Other shorter-term projects we’ve worked on in the past include various game AIs and applications of different AI and ML algorithms and models, such as RNNs for lyrics generation or simulated annealing for prettifying graphs.

Many of our members and officers are already doing undergraduate research in the field of Machine Learning. We are hoping to grow this community of undergraduate researchers by providing our members with the resources of and connections to ML labs (or labs that can use ML).

If you’d like to know more about us, please visit our website, join our Slack, or like our Facebook page. Or feel free to get in touch with our External Relations officer, Raphael Gontijo Lopes.

We welcome The Agency to ML@GT family.

ML@GT Seminar by Le Song (CSE) on “Embedding as a Tool for Algorithm Design” on April 5, 2017, 12:00n in EBB CHOA Room

SpeakerLe Song,  Computational Science and Engineering (CSE), GA Techls

Location: Engineered Biosystems Building, CHOA Room (Map)

Date/Time: April 5, 2017, 12:00n – 1:00pm (Lunch at 11:30am)

Title: Embedding as a Tool for Algorithm Design

Abstract: Many big data analytics problems are intrinsically complex and hard, making the design of effective and scalable algorithms very challenging. Domain experts need to perform extensive research, and experiment with many trial-and-errors, in order to craft approximation or heuristic schemes that meet the dual goals of effectiveness and scalability. Very often, restricted assumptions about the data, which are likely to be violated in real world, are made in order for the algorithms to work and obtain performance guarantees. Furthermore, previous algorithm design paradigms seldom systematically exploit a common trait of real-world problems: instances of the same type of problem are solved repeatedly on a regular basis, differing only in their data. Is there a better way to design effective and scalable algorithms for big data analytics?

I will present a framework for addressing this challenge based on the idea of embedding algorithm steps into nonlinear spaces, and learn these embedded algorithms from problem instances via either direct supervision or reinforcement learning. In contrast to traditional algorithm design where every step in an algorithm is prescribed by experts, the embedding design will delegate some difficult algorithm choices to nonlinear learning models so as to avoid either large memory requirement, restricted assumptions on the data, or limited design space exploration. I will illustrate the benefit of this new design framework using large scale real world data, including a materials discovery problem, a recommendation problem over dynamic information networks, and a problem of learning combinatorial algorithms over graphs. The learned algorithms can reduce memory usage and runtime by orders of magnitude, and sometimes result in drastic improvement in predictive performance.

ML@GT Seminar by Manos Antonakakis (ECE) on “Using DNS & Machine Learning to Reason About Internet Abuse” at 12n on March 29, 2017, in Nano 1117/8

Speaker: Manos Antonakakis, School of Electrical and Computer Engineering (ECE), GA Tech

Location: Marcus Nanotechnology 1117-1118 (Map)

Date/Time: March 29, 2017, 12:00n – 1:00pm (Lunch at 11:30am)Title: Using DNS & Machine Learning to Reason About Internet Abuse

Title: Using DNS & Machine Learning to Reason About Internet Abuse

Abstract: The Domain Name System (DNS) is a critical component of the Internet. The critical nature of DNS often makes it the target of direct cyber-attacks and other forms of abuse. Cyber-criminals rely heavily upon the reliability and scalability of the DNS protocol to serve as an agile platform for their illicit network operations. For example, modern malware and Internet fraud techniques rely upon the DNS to locate their remote command-and-control (C&C) servers through which new commands from the attacker are issued, serve as exfiltration points for the information stolen from the victim’s computer and to manage subsequent updates to their malicious toolset.

In this talk, I will discuss how we can reason about Internet abuse using DNS and various machine learning methods. After providing an overview around DNS, botnets and their illicit activities, I will discuss how spectral methods can help us model one of the most agile threats on the Internet; the botnets that employ Domain Name Generation Algorithms (DGAs). Then, we will discuss ways that tensors can help us track virtual illicit actors across the Internet. Finally, I will conclude by discussing some open research problems in computer security where machine learning methods should be the key ingredient for any efficient and effective solution.
