Activation Functions in Neural Networks [12 Types & Use Cases]

WebJan 3, 2024 · When you are implementing binary_crossentropy loss in your code, Keras automatically takes the output and applies a threshold of 0.5 to the value. This makes anything above 0.5 as 1 and anything below as 0. Unfortunately, in keras there is no easy way to change the threshold. You will have to write your own loss function. WebOct 21, 2024 · 1 Answer. The weight deltas of input nodes involve input values. When using the binary representation, an input node may have value 0, meaning that its weight delta is 0.
