Definition

Artificial Intelligence (AI) is the field of computer science dedicated to creating systems that can perform tasks typically requiring human intelligence. These tasks include learning from experience, recognizing patterns, making decisions, solving complex problems, understanding natural language, and perceiving the environment. Modern AI systems can now surpass human performance in specific domains while remaining specialized rather than general-purpose.

How It Works

Artificial Intelligence encompasses a broad range of technologies and approaches that enable computers to perform tasks traditionally requiring human cognitive abilities. AI systems can learn from data, recognize patterns, make decisions, and solve complex problems.

The field combines multiple disciplines:

  • Computer Science: Algorithms and computational methods
  • Mathematics: Statistics, probability, and optimization
  • Psychology: Understanding human cognition and behavior
  • Philosophy: Questions about consciousness and intelligence

Modern AI Architecture

Contemporary AI systems typically use:

  • Large Language Models (LLMs): Neural networks trained on vast text datasets
  • Transformer Architecture: Attention mechanisms for processing sequential data
  • Multimodal Models: Systems that can process text, images, audio, and video
  • Foundation Models: Large-scale models that can be adapted to multiple tasks
  • Neural Networks: Brain-inspired computational models with multiple layers

Types

Artificial Narrow Intelligence (ANI)

  • Specialized systems: Designed for specific tasks
  • Limited scope: Cannot perform outside their domain
  • Examples: Image recognition, language translation, game playing, protein folding prediction
