10th Annual Machine Learning Symposium
Friday, March 4, 2016
The New York Academy of Sciences
Machine Learning, a subfield of computer science, involves the development of mathematical algorithms that discover knowledge from specific data sets, and then "learn" from the data in an iterative fashion that allows predictions to be made. Today, Machine Learning has a wide range of applications, including natural language processing, search engine functionality, medical diagnosis, credit card fraud detection, and stock market analysis.
This symposium — the tenth in an ongoing series presented by the Machine Learning Discussion Group at the New York Academy of Sciences — will feature Keynote Presentations from leading scientists in both applied and theoretical Machine Learning.

Online Methods for Learning in Social Networks
Alexander Rakhlin, PhD, University of Pennsylvania
We consider the problem of predicting a binary label for an individual given the information about the person and her position within a network. Such a fusion of the two sources of information naturally arises in a variety of applications, including recommendation systems, ad placement, and personalized medical care.
When formalizing this problem, one faces a computationally intractable combinatorial objective. We present an unexpected phenomenon: it is possible to develop poly-time (and statistically near-optimal) online prediction methods even when the offline problem is provably hard. These prediction methods arise in a systematic way from a new online relaxation framework. Our approach naturally extends to the contextual multi-armed bandit setting with large sets of policies—a notoriously difficult problem, which is often encountered in real-world applications.

Personalized Mobile Health Interventions
Ambuj Tewari, PhD, University of Michigan, Ann Arbor
Mobile health (mHealth) refers to the use of mobile devices in accessing and delivering healthcare services. The growing use of mobile phones worldwide along with increasing barriers to receiving quality healthcare is sparking tremendous interest in mHealth both in academia as well as in industry. However, to realize the true potential of mHealth, we need interdisciplinary collaborations between specialists in behavioral sciences, human computer interaction, machine learning and statistics. I will describe Just-in-time Adaptive Intervention (JITAI), a conceptual framework designed to facilitate interdisciplinary communication in mHealth. I will also highlight the role of reinforcement learning algorithms in personalizing mHealth interventions to suit the needs of individuals at particular moments in their daily lives.
New Results at the Crossroads of Convexity, Learning and Information Theory
Sebastien Bubeck, PhD, Theory Group, Microsoft Research
I will present three new results: (i) the Cramer transform of the uniform measure on a convex body is a universal self-concordant barrier; (ii) projected gradient descent with Gaussian noise allows to sample from a log-concave measure in polynomial time; and (iii) Thompson sampling combined with a multi-scale exploration solves the Bayesian convex bandit problem. The unifying theme in these results is the interplay between concepts from convex geometry, learning and information theory.
Smooth Operators: The Rise of Differentiable Attention in Deep Learning
Alex Graves, PhD, Google DeepMind
The ability to focus on one thing and ignore others plays a vital role in guiding human cognition. As well as allowing us to pick out salient information from noisy data, selective attention makes it possible to pursue one thought at a time, to remember one event rather than all events. This talk charts the recent introduction of smooth attention mechanisms into deep learning, which has made it feasible for neural networks to learn how to filter both external data and their own internal representations and manipulations of prior data. Crucially, because these mechanisms are differentiable, they can be trained with gradient descent, using only input and output examples. The talk will review a range of range of neural networks incorporating various forms of textual, visual and internal attention.
