and perform the taskgiven by human.1.7   Programming with and withoutAI?A typical program has three major segmentsinput, processing and output.

The comparison between regular programming and AIprogramming is described in the below table:Table 1: Programming with andwithout AI Segment Regular Programming AI Programming Input In regular programming, input is a sequence of alphanumeric symbols presented and stored as per some given set of previously stipulated rules and that uses a limited set of communication media such as keyboard, mouse, disc, etc. In Artificial Intelligence programming, the input may be a sight, sound, touch, smell or taste. Sight means one dimensional symbol such as typed text, two dimensional objects or three dimensional scenes.

Sound input includes spoken language, music, noise made by objects. Touch includes temperature, smoothness, resistance to pressure. Smell input includes odors emanating from animate and inanimate objects. And taste input includes sweet, sour, salty, bitter foodstuffs and chemicals. Processing In regular programming, processing means manipulation of the stored symbols by a set of previously defined algorithms.

In AI programming, processing includes knowledge representation and pattern matching, search, logic, problem solving and learning. Output In regular programming, output is a sequence of alphanumeric symbols, may be in a given set of colors, that represents the result of the processing and that is placed on such a medium as a CRT screen, paper, or magnetic disk. In AI programming, output can be in the form of printed language and synthesized speech, manipulation of physical objects or locomotion i.e., movement in space.

Machine Learning Machine learning is a subset of the larger artificial intelligence category. Cognitive Computing It means the same as artificial intelligence Neural Network A computer system inspired by living brains. Algorithm A process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer. Data Mining It is all about looking for patterns in a set of data. It identifies correlations and trends that might otherwise go unnoticed.

Natural Language Processing It is an area of artificial intelligence related to understanding and generating speech the way humans usually use it. Turing Test The Turing Test is named for its inventor, Alan Turing, an early computer scientist who theorized extensively about artificial intelligence.
