Artificial intelligence (AI) is intelligence exhibited by machines.

In computer science, the field of AI research defines itself as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of success at some goal.

Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving" (known as Machine Learning).

As machines become increasingly capable, mental facilities once thought to require intelligence are removed from the definition.

For instance, optical character recognition is no longer perceived as an example of "artificial intelligence", having become a routine technology.

Capabilities currently classified as AI include successfully understanding human speech, competing at a high level in strategic game systems (such as Chess and Go), self-driving cars, intelligent routing in content delivery networks, and interpreting complex data.

Perception (from the Latin perceptio, percipio) is the organization, identification, and interpretation of sensory information in order to represent and understand the environment.

All perception involves signals in the nervous system, which in turn result from physical or chemical stimulation of the sense organs.

For example, vision involves light striking the retina of the eye, smell is mediated by odor molecules, and hearing involves pressure waves.

Perception is not the passive receipt of these signals, but is shaped by learning, memory, expectation, and attention.

Advertising is an audio or visual form of marketing communication that employs an openly sponsored, nonpersonal message to promote or sell a product, service or idea.

Sponsors of advertising are often businesses who wish to promote their products or services.

Advertising is differentiated from public relations in that an advertiser usually pays for and has control over the message.

It is differentiated from personal selling in that the message is nonpersonal, i.e., not directed to a particular individual.
