This process is known as backpropagation, where the error signal is propagated backward through the network, allowing the weights to be adjusted iteratively.

Key Components of Deep Learning Models

Deep learning models are built upon the foundation of artificial neural networks. These networks are composed of interconnected nodes, called neurons, organized in layers.

Neural Networks

Neural networks are structured as interconnected layers of neurons, each layer performing a specific computation on the input data.

Layers

Deep learning models typically consist of multiple layers, each layer learning different features from the data. These layers can be categorized into:

Input layer: Receives the raw data as input.
Hidden layers: Perform intermediate computations on the data.
Output layer: Produces the final output of the model.

Activation Functions

Activation functions are mathematical functions applied to the output of each neuron. They introduce non-linearity into the network, allowing it to learn complex patterns. Common activation functions include:

Sigmoid: Squashes the output to a range between 0 and 1.
ReLU (Rectified Linear Unit): Outputs the input directly if it’s positive, otherwise outputs zero.
Tanh (Hyperbolic Tangent): Squashes the output to a range between -1 and 1.
