arbitrary convex function. But it needs to set a K-value as much as dropout.For the sake of understanding, it is assumed that there is a neural network consisting of 1 nodes in layer I with 2 nodes (i+1). Activation value out = f (w.x+b); f is the activation function. ’.’ Here stands for inner product;So when we use Maxout (set k=5) on the (i+1) layer and then output it, the situation changes. At this point the network form on the appearance of the above, with a formula to show that is:Z1 = W1.

used for the partial or forward relationship between two nodes in the table. If PI must be completed before PJ, it can be written as pi → PJ, that is, Pi is the direct frontend of PJ, and PJ is the direct successor of pi. In the frontend diagram, the node without the frontend is called the initial node, and the node without the successor is called the end node.
