Neural networks are computational models inspired by the human brain's structure and function. They consist of layers of interconnected nodes (neurons) that process data through weighted connections. Here's a breakdown:

🧠 Core Components

  • Input Layer: Receives raw data (e.g., images, text)
  • Hidden Layer(s): Processes data through non-linear transformations
  • Output Layer: Produces final predictions or classifications
  • Weights & Biases: Adjustable parameters that determine the model's learning

🔁 Training Process

  1. Forward propagation: Data moves through the network
  2. Loss calculation: Measures prediction accuracy
  3. Backpropagation: Adjusts weights via gradient descent
  4. Iterative refinement: Repeats until optimal performance
