Theoretical Machine Learning Seminar

Efficient Robot Skill Learning via Grounded Simulation Learning, Imitation Learning from Observation, and Off-Policy Reinforcement Learning
Peter Stone
3:00pm|Remote Access Only - see link below

For autonomous robots to operate in the open, dynamically changing world, they will need to be able to learn a robust set of skills from relatively little experience. This talk begins by introducing Grounded Simulation Learning as a way to bridge...

Generalized Energy-Based Models
Arthur Gretton
12:30pm|Remote Access Only - see link below

I will introduce Generalized Energy Based Models (GEBM) for generative modelling. These models combine two trained components: a base distribution (generally an implicit model), which can learn the support of data with low intrinsic dimension in a...

Priors for Semantic Variables
Yoshua Bengio
3:00pm|Remote Access Only - see link below

Some of the aspects of the world around us are captured in natural language and refer to semantic high-level variables, which often have a causal role (referring to agents, objects, and actions or intentions). These high-level variables also seem to...

Graph Nets: The Next Generation
Max Welling
12:30pm|Remote Access Only - see link below

In this talk I will introduce our next generation of graph neural networks. GNNs have the property that they are invariant to permutations of the nodes in the graph and to rotations of the graph as a whole. We claim this is unnecessarily restrictive...

Relaxing the I.I.D. Assumption: Adaptive Minimax Optimal Sequential Prediction with Expert Advice
Jeffrey Negrea
12:30pm|Remote Access Only - see link below

We consider sequential prediction with expert advice when the data are generated stochastically, but the distributions generating the data may vary arbitrarily among some constraint set. We quantify relaxations of the classical I.I.D. assumption in...

Role of Interaction in Competitive Optimization
Anima Anandkumar
3:00pm|Remote Access Only - see link below

Competitive optimization is needed for many ML problems such as training GANs, robust reinforcement learning, and adversarial learning. Standard approaches to competitive optimization involve each agent independently optimizing their objective...

Machine learning-based design (of proteins, small molecules and beyond)
Jennifer Listgarten
12:30pm|Remote Access Only - see link below

Data-driven design is making headway into a number of application areas, including protein, small-molecule, and materials engineering. The design goal is to construct an object with desired properties, such as a protein that binds to a target more...

Instance-Hiding Schemes for Private Distributed Learning
3:00pm|Remote Access Only - see link below

An important problem today is how to allow multiple distributed entities to train a shared neural network on their private data while protecting data privacy. Federated learning is a standard framework for distributed deep learning Federated...

Generalizable Adversarial Robustness to Unforeseen Attacks
Soheil Feizi
12:30pm|Remote Access Only - see link below

In the last couple of years, a lot of progress has been made to enhance robustness of models against adversarial attacks. However, two major shortcomings still remain: (i) practical defenses are often vulnerable against strong “adaptive” attack...

The challenges of model-based reinforcement learning and how to overcome them
Csaba Szepesvari
3:00pm|Remote Access Only - see link below

Some believe that truly effective and efficient reinforcement learning algorithms must explicitly construct and explicitly reason with models that capture the causal structure of the world. In short, model-based reinforcement learning is not...
