One nose but two nostrils: Learn to align with sparse connections between two olfactory cortices

no code implementations6 May 2024 Bo Liu, Shanshan Qin, Venkatesh Murthy, Yuhai Tu

We next compared the alignment performance of local Hebbian rule and the global stochastic-gradient-descent (SGD) learning for artificial neural networks.

Feature Grouping and Sparse Principal Component Analysis with Truncated Regularization

1 code implementation25 Jun 2021 Haiyan Jiang, Shanshan Qin, Oscar Hernan Madrid Padilla

In this paper, we consider a new variant for principal component analysis (PCA), aiming to capture the grouping and/or sparse structures of factor loadings simultaneously.

Dimensionality Reduction feature selection

Contrastive Similarity Matching for Supervised Learning

no code implementations24 Feb 2020 Shanshan Qin, Nayantara Mudur, Cengiz Pehlevan

We propose a novel biologically-plausible solution to the credit assignment problem motivated by observations in the ventral visual pathway and trained deep neural networks.
