A Study of Learning Issues in Feedforward Neural Networks

open access: yesMathematics, 2022
When training a feedforward stochastic gradient descendent trained neural network, there is a possibility of not learning a batch of patterns correctly that causes the network to fail in the predictions in the areas adjacent to those patterns.
