Neural Network Fundamentals:
A neural network is a computational model inspired by the structure and functioning of biological brns. It consists of interconnected nodes or neurons organized in layers, including an input layer, one or more hidden layers, and an output layer. The essence of a neural network lies in its ability to learn from data through adjusting the weights associated with these connections based on error backpropagation.
Key Dynamics:
Forward Propagation: Data flows through the network, passing through each layer until it reaches the output layer. Each neuron computes a weighted sum of inputs and applies an activation function to produce an output that is passed onto subsequent layers or used as the final prediction.
Backpropagation: The learning process involves comparing the predicted output with the actual target values. The error is calculated, and then propagated backward through the network. This step adjusts the weights based on how much each weight contributed to the error in prediction.
Gradient Descent: A crucial optimization algorithm used during backpropagation, gradient descent minimize the loss function by iteratively adjusting the weights of the neural network parameters in the direction opposite to the gradient of the loss function with respect to the weights.
Learning Rate: This parameter determines how much we adjust the weights during each iteration. A high learning rate might cause the model to overshoot the optimal solution, whereas a low learning rate could result in slow convergence or getting stuck in local minima.
Activation Functions: These introduce non-linearity into the network and are critical for its ability to learn complex patterns. Commonly used activation functions include sigmoid, ReLU Rectified Linear Unit, and tanh.
