Use of Deterministic Transforms to Design Weight Matrices of a Neural Network

no code implementations6 Oct 2021 Pol Grau Jurado, Xinyue Liang, Alireza M. Javid, Saikat Chatterjee

For the existing SSFN, a part of each weight matrix is trained using a layer-wise convex optimization approach (a supervised training), while the other part is chosen as a random matrix instance (an unsupervised training).

A Low Complexity Decentralized Neural Net with Centralized Equivalence using Layer-wise Learning

no code implementations29 Sep 2020 Xinyue Liang, Alireza M. Javid, Mikael Skoglund, Saikat Chatterjee

We design a low complexity decentralized learning algorithm to train a recently proposed large neural network in distributed processing nodes (workers).

Predictive Analysis of COVID-19 Time-series Data from Johns Hopkins University

no code implementations7 May 2020 Alireza M. Javid, Xinyue Liang, Arun Venkitaraman, Saikat Chatterjee

We provide a predictive analysis of the spread of COVID-19, also known as SARS-CoV-2, using the dataset made publicly available online by the Johns Hopkins University.

Asynchronous Decentralized Learning of a Neural Network

no code implementations10 Apr 2020 Xinyue Liang, Alireza M. Javid, Mikael Skoglund, Saikat Chatterjee

In this work, we exploit an asynchronous computing framework namely ARock to learn a deep neural network called self-size estimating feedforward neural network (SSFN) in a decentralized scenario.
