TITLE:	  Metamers Of Neural Networks Reveal Divergence From Human
 	   Perceptual Systems


SPEAKER:  JENELLE FEATHER  (MIT)


ABSTRACT:

Artificial neural networks now achieve human-level performance on tasks such as 
image and speech recognition, raising the question of whether they should be 
taken seriously as models of biological sensory systems.  Such neural network 
models exhibit human-like patterns of behavior, and their feature spaces 
reliably predict brain activity.  On the other hand, neural network models can 
often be fooled by small adversarial perturbations that have no effect on 
humans.  In this talk, I will detail our work using “model metamers” to 
investigate similarities between neural networks and human sensory systems. 
Model metamers are physically distinct stimuli that produce nearly the same 
response within a model, and thus the same model prediction.  Our results show 
that despite replicating aspects of human behavior and neural responses, 
present-day deep neural networks learn invariances that deviate markedly from 
those of biological sensory systems.  Model metamers may help guide future 
model refinements to reduce or eliminate these discrepancies.
