Flexible Context-Driven Sensory Processing in Dynamical Vision Models

NeurIPS 2024poster

Visual representations become progressively more abstract along the cortical hierarchy. These abstract representations define notions like objects and shapes, but at the cost of spatial specificity. By contrast, low-level regions represent spatially local but simple input features. How do spatially…

Computing a human-like reaction time metric from stable recurrent vision models

NeurIPS 2023spotlight

The meteoric rise in the adoption of deep neural networks as computational models of vision has inspired efforts to ``align” these models with humans. One dimension of interest for alignment includes behavioral choices, but moving beyond characterizing choice patterns to capturing temporal aspects o…

Tracking Without Re-recognition in Humans and Machines

NeurIPS 2021poster

Imagine trying to track one particular fruitfly in a swarm of hundreds. Higher biological visual systems have evolved to track moving objects by relying on both their appearance and their motion trajectories. We investigate if state-of-the-art spatiotemporal deep neural networks are capable of the s…

Stable and expressive recurrent vision models

NeurIPS 2020spotlight

Primate vision depends on recurrent processing for reliable perception. A growing body of literature also suggests that recurrent connections improve the learning efficiency and generalization of vision models on classic computer vision challenges. Why then, are current large-scale challenges domina…
