Unit 1: Introduction and Overview

5. ......................... in AI has focused chiefly on the following components of intelligence: Notes
learning, reasoning, problem-solving, perception, and language-understanding.
6. A generic term commonly used to indicate the inclusion in software of some type of
automated application of rules, the results of which give the appearance of “.........................”
on the part of the computer.

1.3 AI Problems and Task Domains

1.3.1 AI Problems

When learning the usual range of tasks that we might look forward to an “intelligent entity” to
perform, we require to take into account both “commonplace” tasks in addition to expert tasks.

Example: The commonplace tasks comprise:
 Identifying people, objects.
 Communicating (via natural language).

 Finding the way around obstructions on the streets.
These tasks are performed by matter of routinely by people and some other animals. Specialist
tasks comprise:

 Medical diagnosis.
 Mathematical problem solving
 Playing games such as chess

Did u know? These tasks cannot be performed by all people, and can only be carried out by
skilled experts.
Now, which of these tasks are simple and which ones are tough? Evidently tasks of the first type
are simple for humans to carry out, and approximately all are able to perform them. The second
range of tasks needs skill development and/or intelligence and only some expert scan execute
them well.

Notes Though, when we see what computer systems have been able to attain to date, we
observe that their accomplishments comprise performing complicated tasks such as medical
diagnosis, carrying out symbolic integration, proving theorems and playing chess.
Alternatively, it has proved to be very firm to make computer systems achieve many routine
tasks that all humans and many animals can do.

Example: Examples of such tasks comprise navigating our route without running into
things, catching prey and averting predators.
Humans and animals are also competent of interpreting multifaceted sensory information. We
are able to identify objects and people from the visual picture that we obtain. We are also able
to carry out compound social functions.
