How Deep Learning Works

Neural Networks

Structure and Function of Neural Networks

Neural networks are the backbone of deep learning. They consist of layers of nodes, or neurons, which are modeled after the human brain’s network of neurons. These layers include:

  • Input Layer: The first layer that receives the input data.
  • Hidden Layers: Intermediate layers that process the inputs received from the input layer. There can be multiple hidden layers in a deep learning model.
  • Output Layer: The final layer that produces the output, such as a classification or prediction.

The connections between neurons have associated weights that are adjusted during the training process to minimize the error in predictions.

Explanation of Neurons, Layers, and Activation Functions

  • Neurons: Basic units of a neural network. Each neuron receives input, processes it, and passes the result to the next layer.
  • Layers: Groups of neurons operating at the same level. Deep learning models have multiple hidden layers that allow for complex representations of data.
  • Activation Functions: Functions applied to the output of each neuron to introduce non-linearity into the model, enabling it to learn from complex data. Common activation functions include:
    • Sigmoid: Outputs values between 0 and 1.
    • ReLU (Rectified Linear Unit): Outputs the input directly if it is positive; otherwise, it outputs zero.
    • Tanh (Hyperbolic Tangent): Outputs values between -1 and 1.

Training and Learning Processes

Overview of Training Processes (e.g., Backpropagation)

Training a neural network involves adjusting the weights of the connections based on the error of the output. This process typically follows these steps:
