Addressing Sample Inefficiency in Multi-View Representation Learning

no code implementations17 Dec 2023 Kumar Krishna Agrawal, Arna Ghosh, Adam Oberman, Blake Richards

In this work, we provide theoretical insights on the implicit bias of the BarlowTwins and VICReg loss that can explain these heuristics and guide the development of more principled recommendations.

Synaptic Weight Distributions Depend on the Geometry of Plasticity

1 code implementation30 May 2023 Roman Pogodin, Jonathan Cornford, Arna Ghosh, Gauthier Gidel, Guillaume Lajoie, Blake Richards

Overall, our work shows that the current paradigm in theoretical work on synaptic plasticity that assumes Euclidean synaptic geometry may be misguided and that it should be possible to experimentally determine the true geometry of synaptic plasticity in the brain.

Beyond accuracy: generalization properties of bio-plausible temporal credit assignment rules

1 code implementation2 Jun 2022 Yuhan Helena Liu, Arna Ghosh, Blake A. Richards, Eric Shea-Brown, Guillaume Lajoie

We first demonstrate that state-of-the-art biologically-plausible learning rules for training RNNs exhibit worse and more variable generalization performance compared to their machine learning counterparts that follow the true gradient more closely.

Investigating Power laws in Deep Representation Learning

no code implementations11 Feb 2022 Arna Ghosh, Arnab Kumar Mondal, Kumar Krishna Agrawal, Blake Richards

Access to task relevant labels at scale is often scarce or expensive, motivating the need to learn from unlabelled datasets with self-supervised learning (SSL).

Current State and Future Directions for Learning in Biological Recurrent Neural Networks: A Perspective Piece

no code implementations12 May 2021 Luke Y. Prince, Roy Henha Eyono, Ellen Boven, Arna Ghosh, Joe Pemberton, Franz Scherr, Claudia Clopath, Rui Ponte Costa, Wolfgang Maass, Blake A. Richards, Cristina Savin, Katharina Anna Wilmes

We provide a brief review of the common assumptions about biological learning with findings from experimental neuroscience and contrast them with the efficiency of gradient-based learning in recurrent neural networks.

Deep Semantic Architecture with discriminative feature visualization for neuroimage analysis

no code implementations29 May 2018 Arna Ghosh, Fabien dal Maso, Marc Roig, Georgios D Mitsis, Marie-Hélène Boudrias

Neuroimaging data analysis often involves \emph{a-priori} selection of data features to study the underlying neural activity.
