Introduction to Neural Networks


Neural networks are computing systems inspired by biological neural networks that constitute animal brains. They are a fundamental building block of modern artificial intelligence and machine learning systems.

What are Neural Networks?

A neural network is a series of algorithms that endeavors to recognize underlying relationships in a set of data through a process that mimics the way the human brain operates.

Key Components

  1. Neurons (Nodes): The basic processing units
  2. Weights: Parameters that transform input data
  3. Activation Functions: Functions that determine if a neuron should be activated
  4. Layers: Groups of neurons that process data sequentially

How They Work

Neural networks process information through interconnected nodes, where each connection has an associated weight. The network learns by adjusting these weights based on training data.

Common Applications

  • Image recognition
  • Natural language processing
  • Speech recognition
  • Recommendation systems
  • Autonomous vehicles

Next Steps

Once you understand the basics, explore:

  • Different types of neural networks (CNN, RNN, LSTM)
  • Training algorithms (backpropagation)
  • Deep learning frameworks (TensorFlow, PyTorch)
