Altering Backward Pass Gradients improves Convergence

Bishshoy Das, Milton Mondal, Brejesh Lall +2

In standard neural network training, the gradients in the backward pass are determined by the forward pass. As a result, the two stages are coupled. This is how most neural network…

Orthogonal Ramanujan Sums, its properties and Applications in Multiresolution Analysis

Devendra Kumar Yadav, Gajraj Kuldeep, S. D. Joshi

Signal processing community has recently shown interest in Ramanujan sums which was defined by S.Ramanujan in 1918. In this paper we have proposed Orthog- onal Ramanujan Sums (ORS)…
