The Computational Magic of the Ventral Stream

I argue that the sample complexity of (biological, feedforward) object recognition is mostly due to geometric image transformations and conjecture that a main goal of the ventral stream – V1, V2, V4 and IT – is to learn-and-discount image transformations. In the first part of the paper I describe a class of simple and biologically plausible memorybased modules that learn transformations from un...

Benchmarking Models of the Ventral Stream

This work establishes a benchmark by which to measure models of the ventral stream using crowd-sourced human behavioral measurements. We collected human error patterns on an object recognition task across a variety of images. By comparing the error pattern of these models to the error pattern of humans, we can measure how similar to the human behavior the model's behavior is. Each model we test...

The Invariance Hypothesis and the Ventral Stream

Unlike Athena, the new ventral stream theory foreshadowed in these pages did not spring fully-formed from the head of Zeus. We: primarily Tomaso Poggio, Fabio Anselmi, Lorenzo Rosasco, Jim Mutch, Andrea Tacchetti, and myself, developed it—and continue to refine it—within a context in which the questions considered in this dissertation loom large. Each of its four main chapters can be read indep...
