Neural network modeling of visual perception and cognition
Recent advances in neural network modeling have enabled major strides in computer vision and other artificial intelligence applications. Artificial neural networks are inspired by the brain, and their computations could be implemented in biological neurons. We seek to develop neural network models that can meet real-world computational challenges faced by biological visual systems and that can also explain detailed patterns of brain and behavioral responses.
Development of statistical inference and visualization methods
Computational neuroscience is entering a new era, where big models meet big data. We develop statistical inference and visualization techniques that help us connect theory and experiment, enabling us, for example, to adjudicate among many candidate neural network models using brain-activity measurements acquired with functional imaging and electrophysiological recordings in animals and humans.

New Publication in Scientific Reports
A new paper, “Extracting and visualizing hidden activations and computational graphs of PyTorch models with TorchLens” led by JohnMark Taylor is now published in Scientific Reports! A tweet thread summarizing the paper is here.
Algonauts Project 2023
Congratulations to Hossein Adeli for winning 2nd place in The Algonauts Project “The 2023 Challenge: How the Human Brain Makes Sense of Natural Scenes'' achieving a challenge score of 63.52! Hossein’s model used a general transformer encoder-decoder to map images to fMRI responses.
