TITLE:
Improving Generalization Performance by Self-Training and Self-Distillation
 
ABSTRACT:
In supervised learning we often seek a model which minimizes (to epsilon optimality) a loss function over a training set, possibly subject to some (implicit or explicit) regularization. Suppose you train...

Title: Efficient compression and linguistic meaning in humans and machines
 
Abstract: In this talk, I will argue that efficient compression may provide a fundamental principle underlying the human capacity to communicate and reason about meaning, and may help to inform machines with similar...

Title: AI for physics & physics for AI
 
Abstract: After briefly reviewing how machine learning is becoming ever-more widely used in physics, I explore how ideas and methods from physics can help improve machine learning, focusing on automated discovery of mathematical formulas from data. I...

Title of the talk: Sobolev Independence Criterion: Non-Linear Feature Selection with False Discovery Control.    
 
Abstract: In this talk I will show how learning gradients help us designing new non-linear algorithms for feature selection, black box sampling and also, in understanding neural...

Abstract:
Developing theoretical foundations for learning is a key step towards understanding intelligence. Supervised learning is a paradigm in which natural or artificial networks learn a functional relationship from a set of n input-output training examples. A main challenge for the theory is...

Abstract: In this talk, I will present a theory of reinforcement learning that falls in between "model-based" and "model-free" approaches. The key idea is to represent a "predictive map" of the environment, which can then be used to efficiently compute values. I show how such a map explains many...

Abstract: Object recognition relies on the hierarchical processing of visual information along the primate ventral stream. Artificial neural networks (ANNs) recently achieved unprecedented accuracy in predicting neuronal responses in different cortical areas and primate behavior. In this talk, I...

Title: Language as a scaffold for learning
 
Abstract:
 
Research on constructing and evaluating machine learning models is driven
almost exclusively by examples. We specify the behavior of sentiment classifiers
with labeled documents, guide learning of robot policies by assigning scores to...

Title:  Unsupervised Learning and Structured Representations in Neural Networks
 
Abstract:
Sample efficiency, transfer, and flexibility are hallmarks of biological intelligence and long-standing challenges for artificial learning systems. Core to these capacities is the reuse of structured...

Using task-optimized neural networks to understand why brains have specialized processing for faces
Previous research has identified multiple functionally specialized regions of the human visual cortex and has started to characterize the precise function of these regions. But why do brains have...
