The History of AI

Study Notes

The History of AI

The concept of artificial beings has been explored in literature since ancient times.
Mary Shelley's Frankenstein and Karel Capek's R.U.R. (Rossum's Universal Robots) explored the ethical implications of creating artificial life.
The study into mechanical, or “formal,” reasoning began with ancient philosophers and mathematicians.
Alan Turing's theory of computation, based on manipulating simple symbols like "0" and "1", demonstrated a machine's ability to simulate any understandable mathematical reasoning.
Turing's insights, known as the Church-Turing thesis, showed how digital computers could mimic any formal reasoning processes.
Scientists began to consider building electronic brains, drawing inspiration from Turing's work alongside discoveries in neurobiology, information theory, and cybernetics.
Turing proposed that if humans couldn't distinguish a machine's responses from a human's, the machine was considered "intelligent".
The creation of "artificial neurons" by McCulloch and Pitts in the 1930s is considered the first work in the field of AI.
Early AI research focused on algorithms simulating humans' step-by-step reasoning when solving puzzles or using logical deduction.
In the late 1980s and 1990s, AI shifted to processing uncertain or incomplete information, incorporating probability and economics.
Complex problems require powerful computational capabilities to perform massive calculations, known as "combinatorial explosion," where memory and computation time become immense.
The primary goal in AI is to find algorithms that solve problems efficiently.
Humans often use quick and intuitive judgments, rather than the step-by-step deduction that early AI emulated.
AI has advanced by utilizing problem-solving "embedded symbolic" approaches: acting agents highlighting the importance of sensorimotor skills for higher reasoning.
Neural network research attempts to model brain structures that create these skills.
Statistical AI approaches emulate human learning abilities.

AI Schools of Thought

Traditional AI focuses on methods like machine learning, characterized by formalism and statistical analysis.
Computational Intelligence emphasizes iterative learning and development, such as adjusting system parameters in connectionist systems.
Hybrid Intelligent Systems combine both schools of thought, where expert systems’ inference rules might be generated by neural networks or statistical learning.
