Training involves adjusting weights and biases so the network can map inputs to outputs accurately. Supervised training uses the train function. In MATLAB 6.0, you can configure training parameters like epochs (iterations), goal (acceptable error), and learning rate ( lr ).
Keep your learning rates low (between ) to prevent numerical oscillations during training.
A single artificial neuron receives one or more inputs, weighs them, sums them up, adds a bias, and passes the result through an (also known as a transfer function) to produce an output. Inputs ( ): The incoming data or signals. Weights (
Introduces basic building blocks like the McCulloch-Pitts neuron, weights, biases, and various activation functions (e.g., sigmoidal, threshold).
