The softmax function, a core component in modern AI systems like large language models, has a history spanning 150 years and originating in diverse scientific fields. Initially developed by physicist Ludwig Boltzmann in 1868 to explain the behavior of gas molecules through the principle of maximum entropy, the same mathematical form later emerged independently. It was rediscovered by a psychologist modeling human choice and subsequently by an engineer seeking to produce valid probabilities from neural network scores. This convergence highlights a fundamental mathematical principle that transcends disciplinary boundaries. AI
