24.10.2019 · This neural network, like all neural networks, will have to learn what the important features are in the data to produce the output. In particular, this neural net will be given an input matrix with six samples, each with three feature columns consisting of solely zeros and ones.
Oct 24, 2019 · We can see that our neural network is already assigning a higher value to the weight connected to the first feature in each input example! def train (self, epochs = 25000): for epoch in range(epochs): self . feed_forward() self . backpropagation() self . error_history . append(np . average(np . abs(self . error))) self . epoch_list . append(epoch)
