    • Supervised Learning: Involves training a model on labeled data, where the correct output is provided for each input.
    • Unsupervised Learning: Involves training a model on unlabeled data to identify underlying patterns and structures.
    • Reinforcement Learning: Involves training a model through trial and error, using rewards and penalties to learn optimal behaviors.
  2. Neural Networks:
    • Neural networks are computational models inspired by the human brain. They consist of layers of interconnected nodes (neurons) that process and transform data.
    • Deep Learning: A subset of neural networks with multiple layers (deep networks) that can learn complex representations from data. Deep learning has driven significant advancements in AI.
  3. Natural Language Processing (NLP):
    • NLP enables AI systems to understand, interpret, and generate human language. It involves tasks such as sentiment analysis, machine translation, and speech recognition.

Example of an AI System:
