11.1. Argmax
11.1.1. Argmax API
- class fhez.nn.activation.argmax.Argmax
Argmax activation, compute sparse array of highest activation.
- backward(gradient: numpy.ndarray)
Calculate the argmax derivative with respect to each input.
Argmax.
- property cost
Get computational cost of this activation.
- forward(x: numpy.ndarray)
Calculate the argmax of some input \(x\) along its first axis.
Argmax.
- update()
Update parameters, so nothing for argmax.
- updates()
Update parameters using average of gradients so none for argmax.
