WitrynaSoftmax is often used as the activation for the last layer of a classification network because the result could be interpreted as a probability distribution. The softmax of each vector x is computed as exp (x) / tf.reduce_sum (exp (x)). The input values in are the log-odds of the resulting probability. Arguments x : Input tensor.
