Introduction to Neural Networks

Neural networks are computing systems inspired by biological neural networks. They form the foundation of deep learning and modern AI applications.

Basic Neural Network Structure

Neurons (Nodes)

Basic processing units that receive inputs, apply weights, and produce outputs through activation functions.

Layers

  • Input Layer: Receives raw data
  • Hidden Layers: Process information between input and output
  • Output Layer: Produces final predictions

Types of Neural Networks

Feedforward Neural Networks

Information flows in one direction from input to output.

Convolutional Neural Networks (CNNs)

Specialized for processing grid-like data such as images.

Recurrent Neural Networks (RNNs)

Designed for sequential data with memory capabilities.

Long Short-Term Memory (LSTM)

Advanced RNN architecture that can learn long-term dependencies.

Training Neural Networks

Forward Propagation

Data flows through the network to produce predictions.

Backpropagation

Algorithm for training networks by adjusting weights based on errors.

Optimization Algorithms

  • Gradient Descent
  • Adam Optimizer
  • RMSprop

Common Challenges

  • Overfitting: Model performs well on training data but poorly on new data
  • Vanishing Gradients: Gradients become too small in deep networks
  • Computational Complexity: Training requires significant resources

Applications

  • Image recognition and classification
  • Natural language processing
  • Speech recognition
  • Autonomous vehicles
  • Medical diagnosis
