“... artificial intelligence [AI] is the science of making machines do

things that would require intelligence if done by [humans]”

HISTORIC ATTEMPTS

The original story, published by Mary Shelley, in 1818, describes the attempt of a true scientist, Victor Frankenstein, to create life.

PURPOSE OF AI

One is to use the power of computers to augment human thinking, just as we use motors to augment human or horse power. Robotics and expert systems are major branches of that.

The other is to use a computer's artificial intelligence to understand how humans think. In a humanoid way. If you test your programs not merely by what they can accomplish, but how they accomplish it, they you're really doing cognitive science; you're using AI to understand the human mind. - Herb Simon

ROBOTICS

1970 Shakey (SRI) was driven by a remote-controlled computer, which formulated plans for moving and acting. It took about half an hour to move Shakey one meter

The Ant, has 17 sensors. They are designed to work in colonies.

HUMAN BRAIN

Most scientists would be happy to view the brain as a vast but complex machine. As such it should then be possible to purely replicate the brain using artificial neurons.

This has already been done for very simple life forms such as insects which only have a few thousand neurons in their brains.

In principle, it would not be necessary to have a full scientific understanding of how the brain works. One would just build a copy of one using artificial materials and see how it

LIMITATIONS OF HUMAN MIND

Object recognition. People cannot properly explain how they recognise objects.

Face recognition. Cannot be passed on to another person by explanation.

Naming of colours. Based on learning, not on absolute standards.

HOW DO WE BUILD A MACHINE THAT CAN IDENTIFY COLOURS

Answer: By building a machine that can learn from human beings.

Criminal tendenciesStock market movements.Popularity ratings of politicians, pop stars, etc.

THE FUTURE?

Idea of Artificial Intelligence is being replaced by Artificial life, or anything with a form or body.

The consensus among scientists is that a requirement for life is that it has an embodiment in some physical form, but this will change. Programs may not fit this requirement for life yet.
