Introduction to Artificial Intelligence

What is Artificial Intelligence?

• Artificial Intelligence simulates human intelligence in machines.
• AI systems use algorithms and data to recognize patterns, make decisions, and improve performance.

• AI technologies make it possible for complex tasks like speech recognition and face detection with high accuracy.

History and Evolution of Artificial Intelligence (AI)

• The earliest AI concepts trace back to ancient Greek mythology.
• The modern AI field emerged in the 1950s with the exploration of creating machines that think, learn, and solve problems.
• Alan Turing proposed the Turing test in 1950 to determine if a machine can exhibit human-like intelligent behavior.
• The field has evolved with machine learning, deep learning, and natural language processing.
• The 1980s and 1990s were marked by expert systems that mimic human expert decision-making.
• The 2000s brought big data and computing resources that led to advanced AI systems.

Core Concepts in AI

• Algorithms learn from data without explicit programming, which defines Machine Learning (ML).
• Neural Networks, inspired by brain structure, mimic neuron interactions for pattern recognition.
• Deep Learning analyzes data using complex, multi-layered neural networks and is a subset of ML.
• Natural Language Processing (NLP) allows computers to process and analyze language data for human-computer interaction.
• Robotics integrates AI with physical machinery to perform tasks from assembly to surgery.
• Cognitive Computing uses AI to mimic human brain processes for complex problem-solving, including pattern recognition, NLP, and data mining.
• Expert Systems emulate human expert decision-making through reasoning.

How AI Works

• Data is collected from various sources and then sorted into categories.
• AI sorts and deciphers data using programmed patterns until similar patterns are recognized.
• AI uses recognized patterns to predict outcomes.
• If data sets are considered a "fail," AI learns from the mistake and repeats the process under different conditions.
• Through the adjustment process, AI is constantly learning and improving.
