James McCaffrey explains what neural network activation functions are and why they're necessary, and explores three common activation functions. Understanding neural network activation functions is ...

Activation functions play a critical role in AI inference, helping to ferret out nonlinear behaviors in AI models. This makes them an integral part of any neural network, but nonlinear functions can ...

Since their simultaneous discovery by two groups 1,2, orexin/hypocretin neurons have been implicated in numerous functions, including regulating sleep/wake cycles, arousal, reward seeking, cognition, ...
