softmaxudgange

Softmaxudgange refers to the output layer of a neural network that uses the softmax activation function. This function is commonly employed in multi-class classification problems where the goal is to assign an input to one of several possible categories. The softmax function takes a vector of real numbers, typically the raw output scores from the previous layer of the network, and transforms them into a probability distribution.

The mathematical formulation of the softmax function for an input vector z is given by:

Softmax(z)_i = exp(z_i) / sum(exp(z_j)) for all j.

This formula ensures that each output value is between 0 and 1, and that the sum of all output values equals 1. Therefore, each output can be interpreted as the probability that the input belongs to a particular class.

For example, in an image classification task with three classes (cat, dog, bird), a neural network with a softmax output layer would produce three values, each representing the predicted probability of the input image being a cat, a dog, or a bird, respectively. The class with the highest probability is typically chosen as the final prediction. The use of softmaxudgange is crucial for obtaining interpretable and well-calibrated probability estimates in classification tasks.
