A Brief Explanation on Adversarial Attack

A Brief Explanation on Adversarial Attack

The core implementation of the neural network is feedforward and backpropagation. Feedforward passes a series of inputs enter the layer, and these inputs are multiplied by the weights. Each value is then added together to get a sum of the weighted input values. It often works with activation functions to
