Turing machines, the number game, and inference

The number game, which stems from Josh Tenenbaum’s PhD thesis, illustrates some important ideas about Bayesian concept learning. Here is a discussion of this in lecture notes from Kevin Murphy for reference. The basic setup is as follows: I give you a set of numbers from 1 to 100, and you try to guess another number in the set. For instance, I give … More Turing machines, the number game, and inference

New paper: sensorimotor integration with travelling waves

Don’t you know about the wave? Everybody knows that the wave is the word. We have a new paper out in Neuron called “A sensorimotor role for traveling waves in visual cortex” (Zanos et al. 2015) [pdf]. Synchronous neuronal activity often propagates parallel to the cortical surface. These traveling waves are a fascinating example of the complex dynamics … More New paper: sensorimotor integration with travelling waves

Hierarchical processing of complex motion

I’m thrilled to announce that our paper, Hierarchical processing of complex motion along the dorsal visual pathway, has been published in PNAS. In this work, we looked at the response properties of neurons in area MST (the medial superior temporal area). MST neurons are part of the dorsal visual pathway; they are strongly selective for … More Hierarchical processing of complex motion
