Kernelized Synaptic Weight Matrices

2018-07-01 · ICML 2018 7 · Lorenz Muller, Julien Martel, Giacomo Indiveri

In this paper we introduce a novel neural network architecture, in which weight matrices are re-parametrized in terms of low-dimensional vectors, interacting through kernel functions. A layer of our network can be interpreted as introducing a (potentially infinitely wide) linear layer between input and output. We describe the theory underpinning this model and validate it with concrete examples, exploring how it can be used to impose structure on neural networks in diverse applications ranging from data visualization to recommender systems. We achieve state-of-the-art performance in a collaborative filtering task (MovieLens).

Dynamics of Structured Complex-Valued Hopfield Neural Networks

2025-03-25 · Rama Murthy Garimella, Marcos Eduardo Valle, Guilherme Vieira, Anil Rayala 외

In this paper, we explore the dynamics of structured complex-valued Hopfield neural networks (CvHNNs), which arise when the synaptic weight matrix possesses specific structural properties. We begin by analyzing CvHNNs wi…

Fast Computation of Moore-Penrose Inverse Matrices
