@datasciencefoundry: Activation functions are what allow neural networks to learn complex, non-linear patterns. 🧠 So what exactly is an activation function? • A neuron first takes its inputs, applies weights, adds a bias, and calculates a value. • The activation function transforms that value before passing it to the next layer. • This transformation introduces non-linearity into the network. Why does that matter? • Without activation functions, stacking multiple layers would still result in a linear transformation. • Non-linearity allows neural networks to learn complex relationships that a simple linear model cannot capture. Activation functions are typically used throughout the hidden layers of a neural network, with the choice depending on the architecture and task. Here are 8 important activation functions to know: • Sigmoid • Tanh • ReLU • Leaky ReLU • PReLU • ELU • SiLU • GELU #ActivationFunctions #NeuralNetworks #DeepLearning #MachineLearning #AI
