Introduction to Artificial Intelligence
- Artificial Intelligence (AI) has been a concept for over 75 years, initially popularized through science fiction.
- Despite early expectations, AI did not immediately revolutionize industries and remained largely theoretical until recent advancements.
- AI is defined by Merriam-Webster as the capability of a machine to imitate intelligent human behavior, though this definition is considered vague.
"The term AI is something which has been there for more than 75 years and this all started by the term being coined and being created as a buzzword in science fictions 75 years back in the '50s."
- Highlights the historical context and initial perceptions of AI in popular culture.
Evolution of Machine Learning
- Machine Learning (ML) emerged in the 1960s as a subset of AI, allowing machines to learn from data without explicit programming.
- Conventional machine learning faced limitations in performance despite extensive data training.
- The Universal Approximation Theorem of 1989 suggested algorithms could learn any phenomenon to any degree of approximation, but practical application was initially unattainable.
"Machine learning then became a part of artificial intelligence and this was in the '60s, late '70s, and '80s when people realized that you don't have to train artificial intelligence; you could use data to make artificial intelligence learn these things all on its own."
- Describes the transition from explicit programming to data-driven learning in AI.
The Advent of Deep Learning
- In 2010, deep learning emerged by leveraging graphics processing units (GPUs) initially designed for gaming, significantly enhancing AI training capabilities.

"AI can hallucinate, and these are things where AI has been wrongly hallucinating things which are not true."
- AI's tendency to produce false information highlights the need for improved accuracy and reliability.
"AI has its own vulnerabilities... an adversarial perturbation can make a stop sign look like a yield sign to AI."
- AI's susceptibility to adversarial attacks illustrates the need for robust security measures.
The Role of Purpose in AI Development
- AI currently lacks a purpose, which is a fundamental difference from human-driven actions.
- Research is underway to imbue AI with purpose, which could lead to autonomous decision-making.
"Everything which we do is because of a purpose, but artificial intelligence has no purpose."
- The absence of purpose in AI distinguishes it from human actions, impacting its decision-making process.
"Once we have this purpose given to AI, that's when AI will start working on its own."
