An additional learnable parameter in neural networks that allows shifting the activation function.
Bias terms enable neurons to activate even when all inputs are zero. Each neuron typically has one bias. They increase model flexibility and are crucial for fitting non-zero-centered data.
Linear transformation: y = Wx + b
Bias in each layer
Offset parameter
A computational model inspired by biological neural networks, consisting of interconnected nodes (neurons) that process information.
Learnable parameters in neural networks that determine the strength of connections between neurons.
Learnable values in a model that are optimized during training (weights and biases).
