Explicitly Modeling Subcortical Vision with a Neuro-Inspired Front-End Improves CNN Robustness

NeurIPS 2025poster

Convolutional neural networks (CNNs) trained on object recognition achieve high task performance but continue to exhibit vulnerability under a range of visual perturbations and out-of-domain images, when compared with biological vision. Prior work has demonstrated that coupling a standard CNN with a…

Wiring Up Vision: Minimizing Supervised Synaptic Updates Needed to Produce a Primate Ventral Stream

ICLR 2022spotlight

After training on large datasets, certain deep neural networks are surprisingly good models of the neural mechanisms of adult primate visual object recognition. Nevertheless, these models are considered poor models of the development of the visual system because they posit millions of sequential, pr…

Neural Population Geometry Reveals the Role of Stochasticity in Robust Perception

NeurIPS 2021poster

Adversarial examples are often cited by neuroscientists and machine learning researchers as an example of how computational models diverge from biological sensory systems. Recent work has proposed adding biologically-inspired components to visual neural networks as a way to improve their adversarial…

Simulating a Primary Visual Cortex at the Front of CNNs Improves Robustness to Image Perturbations

NeurIPS 2020spotlight

Current state-of-the-art object recognition models are largely based on convolutional neural network (CNN) architectures, which are loosely inspired by the primate visual system. However, these CNNs can be fooled by imperceptibly small, explicitly crafted perturbations, and struggle to recognize obj…
