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, ...

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 ...

Understanding how to use non-standard activation functions allows you to customize a neural network system. A neural network loosely models biological synapses and neurons. Neural network (NN) ...

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 ...

Macrophages are central to tissue development, homeostasis and inflammation, but they also contribute to a broad spectrum of inflammatory pathologies and thus represent key therapeutic targets 1.
