Here, I have the single hidden layer multi-layer perceptron (Input: 4 units, hidden unit: 3 units, output: 1 unit).
I want to do pruning before a training process with Keras. Concretely, I just want to remove the connection between the input units and hidden units. (so I don't remove the hidden units.)
Would you tell me how to implement this code? Now I am thinking that the skip connection with merge and concat is one of the solution, however, it is not smart way when the number of the units and layers are increased.
