Representational dissimilarity metric spaces for stochastic neural networks

1 code implementation21 Nov 2022 Lyndon R. Duong, Jingyang Zhou, Josue Nassar, Jules Berman, Jeroen Olieslagers, Alex H. Williams

Quantifying similarity between neural representations -- e. g. hidden layer activation vectors -- is a perennial problem in deep learning and neuroscience research.

BAM: Bayes with Adaptive Memory

no code implementations4 Feb 2022 Josue Nassar, Jennifer Brennan, Ben Evans, Kendall Lowrey

Online learning via Bayes' theorem allows new data to be continuously integrated into an agent's current beliefs.

BAM: Bayes Augmented with Memory

no code implementations ICLR 2022 Josue Nassar, Jennifer Rogers Brennan, Ben Evans, Kendall Lowrey

Online learning via Bayes' theorem allows new data to be continuously integrated into an agent's current beliefs.

On 1/n neural representation and robustness

1 code implementation NeurIPS 2020 Josue Nassar, Piotr Aleksander Sokol, SueYeon Chung, Kenneth D. Harris, Il Memming Park

In this work, we investigate the latter by juxtaposing experimental results regarding the covariance spectrum of neural representations in the mouse V1 (Stringer et al) with artificial neural networks.
