Abstract: Local perturbation of neural activity in high-level visual cortical areas alters visual perception. Quantitative characterization of these perceptual alterations holds the key to understanding the mapping between patterns of neuronal activity and elements of perception. The complexity and...

Daniel Mitropolsky, Columbia University
Abstract: How do neurons, in their collective action, beget cognition, as well as intelligence and reasoning? As Richard Axel recently put it, we do not have a logic for the transformation of neural activity into thought and action; discerning this logic as the most important future direction of...

Abstract:
Across the primate neocortex, neurons that perform similar functions tend to be spatially grouped together. How such organization emerges and why have been debated extensively, with various models successfully replicating aspects of cortical topography using cost functions and learning...

Aran Nayebi, ICoN Postdoctoral Fellow at MIT
Abstract:
Deep neural networks trained on high-variation tasks ("goals”) have had immense success as predictive models of the human and non-human primate visual pathways. More specifically, a positive relationship has been observed between model performance on ImageNet categorization and neural...

H. N. Mhaskar - Claremont Graduate University, Claremont.
The fundamental problem of machine learning is often formulated as the problem of function approximation. For example, we have data of the form {(xj,yj)}, where yj is the class label for xj, and we want to approximate the class label as a function of the input x. The standard way for this...

Meenakshi Khosla (Kanwisher lab postdoc)
Abstract: Neuroscience is currently undergoing an explosion in the availability of large-scale brain activity data, so the major challenge no longer lies in data collection, but also in deriving understanding from this abundant stream of complex, high-dimensional, noisy data with methods that fully...

Akhilan Boopathy, MIT graduate student in the Fiete Lab
Abstract: The measure of a machine learning algorithm is the difficulty of the tasks it can perform, and sufficiently difficult tasks are critical drivers of strong machine learning models. However, quantifying the generalization difficulty of machine learning benchmarks has remained challenging....

In person and open to the MIT Community.
Abstract:
Visual attention and working memory are two different cognitive functions. However, because of their close relationship and interactions, it is often claimed that they share the same underlying neuronal mechanisms. Here, I will first describe...

This is meant to be an informal discussion in which Phillip and Brian will give an overview of transformer networks and then we will open the floor for questions and discussion. It is likely that we will have another meeting at a later time discussing what transformers may contribute to...
