Deep learning is a subset of machine learning that uses algorithms to model complex patterns in data. 🧠✨ Here's a concise guide to get started:

What is Deep Learning?

  • Definition: A machine learning technique that uses layered neural networks to learn hierarchical representations of data.
  • Key Idea: Mimics the human brain's ability to process information through interconnected nodes (neurons).
  • Use Cases: Image recognition, natural language processing, autonomous vehicles, etc.

Core Concepts

  • Neurons & Layers: Basic units of computation organized into input, hidden, and output layers.
  • Activation Functions: Non-linear functions (e.g., ReLU, Sigmoid) that determine neuron output.
  • Backpropagation: Algorithm for adjusting weights based on error gradients. 🔄
