How Hidden Layer Works

Introduction to Hidden Layers

Hidden layers are integral components of neural networks. They exist between the input layer and the output layer, serving as intermediate processing stages.
Each hidden layer consists of nodes (neurons) that transform input data through weighted connections and activation functions, enabling the network to learn and model complex data patterns.

Role of Weights and Biases

Weights and biases are key to the functioning of hidden layers. Weights determine the strength of connections between nodes, while biases allow the network to shift activation functions.
Together, these parameters are optimized during training to minimize error and enhance the network’s predictive accuracy.

Activation Functions in Hidden Layers

Activation functions introduce non-linearity into the model, enabling hidden layers to learn intricate relationships in data. Common activation functions include ReLU, Sigmoid, and Tanh.
These functions help the network identify patterns that linear models cannot, making hidden layers essential for solving complex problems.

Training and Backpropagation

During training, the network uses backpropagation to adjust weights and biases in the hidden layers. Errors are propagated backward from the output layer to update parameters,
ensuring the model learns effectively. Hidden layers become more adept at feature extraction with each iteration.

Types of Hidden Layer

• Dense Layer. A fully connected layer where each node is connected to every node in the previous and next layers, often used for general-purpose feature extraction.
• Convolutional Layer. Processes grid-like data such as images, extracting spatial features using convolutional filters.
• Recurrent Layer. Retains memory of previous inputs to process sequential data like time series or text.
• Dropout Layer. Temporarily disables random nodes during training to prevent overfitting and improve generalization.
• Batch Normalization Layer. Normalizes inputs to stabilize training and improve convergence speed.

Algorithms Used in Hidden Layer

• Backpropagation Algorithm. Adjusts weights and biases in hidden layers by minimizing the error between predicted and actual outputs.
• Gradient Descent. Optimizes hidden layer parameters by iteratively updating weights based on the gradient of the error function.
• Adam Optimizer. Combines momentum and adaptive learning rates to fine-tune hidden layer parameters efficiently.
• Stochastic Gradient Descent (SGD). Updates weights for a single training example or a small batch at a time, making it suitable for large datasets.
• Regularization Techniques. Techniques like L1, L2, and dropout prevent overfitting by imposing constraints on hidden layer weights.
