Artificial Intelligence
|
Theory:
study of how ideas that enable computers to be intelligent. making the computer think as a human being thinks. (process + research) Application: how we make computers perform intelligent tasks which are now doable only by humans. producing "intelligent" output w/o duplicating human thought processes. (outcome + industry) |
|
|
Artificial Intelligence Goals
|
Theoretical: understanding the principles which enable intelligent behavior.
Practical: Solve problems that could not previously be solved by a computer. |
|
|
3 key features of intelligence
|
1.intentionality
2. flexibility 3. productive laziness |
|
|
Intentionality
|
Having a goal, a reason for doing something. It is how we repsent things. internal state= referring to concrete or abstract entities
key= representation |
|
|
Felxibiity
|
types of goals: objects, plans, and actions
understading that we are failing, and creating something new. computer is rigid. graceful degradation: if a problem confronts you, you won't just stop. (comp. will) |
|
|
Productive Laziness
|
Do-Easy Method: doing things in the easiest most relaxed manner achievable.
Enumerate options= combinatorial explosion. Shortcut requires: description of problem, recongnizing, analyzing, this is learning!! |

Eliza
|
1966
Joseph Weizenbaum. Rogerian Therapist: parody of responses by a nond-directional psychotherapist in an initial psychiatric interview. |
|
|
Eliza Operation
|
Topic: match user topics, track topics.
Response types: general prompt, transform user statement, relevant to topic. Cycle: get input, respond. Steps: change point of view oof a pattern is found when change response. |
|
|
Eliza Patterns
|
List of words: wildcards.
Pattern= template Input Pattern: list of keywords, substitutions, classes of keyword. Multi-response= 2 or more responses used. methods: give weights, choose randomly. |
|
|
Eliza Lacks
|
initiative, misinterprets word meanings, cannot match all patterns, common sense, world knowleddge, felxibility.
No syntax represenations, must use pattern for every meaning. no knowledge of topic which are discussed. Human posses: world knowledge, common sense, kownledge of topics and participants. |
