// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM

Softmax

Softmax is a mathematical function that converts a list of numbers into probabilities, where all probabilities add up to one.

TECHNICAL DEFINITION

Softmax is an activation function applied to the output layer of a neural network, typically for multi-class classification, transforming raw scores (logits) into a probability distribution over predicted classes.

BACKGROUND

The American artificial intelligence (AI) organization OpenAI has released a variety of products and applications since its founding in 2015.
