On November 7, 2024 at 14:00 the general seminar of IIAP will be held (the seminar's room, IV floor). On the agenda there is the report of Edgar Vardanyan on "Analyzing Steady State Variance in Hebbian Learning: A Moment Closure Approach". Abstract: Hebbian learning, an important concept in neural networks, is the basis for various learning algorithms that model the adaptation of neural connections, also known as synapses. Among these models, Oja’s Rule stands out as an important example, giving valuable insights into the dynamics of unsupervised learning algorithms. The fact that the final steady state solution of a single layer network that learns using Oja's rule equals to the solution of Principal component analysis is well known. However, the way learning rate can affect the variance of the final parameters is less explored. In this paper, we investigate how different learning rates can influence the variance of parameters in Oja's Rule, utilizing the moment closure approximation. By focusing on the variance, we offer new perspectives on the behavior of Oja's Rule under varying conditions. We derive a closed form equation which connects the parameter variance with the learning rate and show that the relationship between these is linear. This gives insights which may help optimize the learning process of Hebbian models. On October 31, 2024 at 12:00 the general seminar of IIAP will be held (the seminar's room, IV floor).
