Introduction to Artificial Intelligence Introduction
What is Artificial Intelligence?
It is a young area of science (1956)
Its goals are what we consider Intelligent behaviour
There are many approaches from different points of view
It has received influence from very diverse areas (Philosophy,Mathematics, Psychology, Biology)
Involves many areas of work with generic goals (learning, perception,problem solving . . .) and specific goals (chess, diagnosis of diseases,driving cars, ...)
Introduction to Artificial Intelligence Introduction
Systems that think rationally
The laws of rationality are based on logic
Formal logic has to be the basis of intelligent systems (Logicism)
There are two obstacles:
It is very difficult to formalize knowledge in logic languageThere is a great leap between the theoretical capacity of logic and itspractical application
Introduction to Artificial Intelligence Introduction
Systems that act rationally
To act rationally means to perform acts to achieve the best outcome,to obtain some goals given some beliefs
The paradigm is the agent
An agent perceives and act, accordingly to the environment it issituated
The capacities that are needed are the same than those to pass theTuring’s test: Natural language processing, knowledge representation,reasoning, learning, perception
It is a more general approach, not centered on the human model
