Adaptive whitening with fast gain modulation and slow synaptic plasticity

1 code implementation NeurIPS 2023 Lyndon R. Duong, Eero P. Simoncelli, Dmitri B. Chklovskii, David Lipshutz

Neurons in early sensory areas rapidly adapt to changing sensory statistics, both by normalizing the variance of their individual responses and by reducing correlations between their responses.

Adaptive coding efficiency in recurrent cortical circuits via gain control

no code implementations31 May 2023 Lyndon R. Duong, Colin Bredenberg, David J. Heeger, Eero P. Simoncelli

Using published V1 population adaptation data, we show that propagation of single neuron gain changes in a recurrent network is sufficient to capture the entire set of observed adaptation effects.

Adaptive whitening in neural populations with gain-modulating interneurons

1 code implementation27 Jan 2023 Lyndon R. Duong, David Lipshutz, David J. Heeger, Dmitri B. Chklovskii, Eero P. Simoncelli

Statistical whitening transformations play a fundamental role in many computational systems, and may also play an important role in biological sensory systems.

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.

Multi-rate adaptive transform coding for video compression

no code implementations25 Oct 2022 Lyndon R. Duong, Bohan Li, Cheng Chen, Jingning Han

Contemporary lossy image and video coding standards rely on transform coding, the process through which pixels are mapped to an alternative representation to facilitate efficient data compression.
