What Are Frames And Scripts In “artificial Intelligence”? |
|
Answer» FRAMES are a variant of semantic networks which is one of the popular ways of presenting non-procedural knowledge in an expert SYSTEM. A frame which is an artificial data STRUCTURE is used to divide knowledge into substructure by representing “stereotyped SITUATIONS’. SCRIPTS are similar to frames, except the values that fill the slots must be ordered. Scripts are used in natural language understanding systems to organize a knowledge base in terms of the situation that the system should understand.

What Are Partial, Alternate, Artificial, Compound And Natural Key? |
|
Answer» It is a SET of attributes that can uniquely identify weak entities and that are related to same owner entity. It is sometime called as DISCRIMINATOR. Alternate Key: All Candidate Keys excluding the Primary Key are known as Alternate Keys. ARTIFICIAL Key: If no obvious key, either stand alone or compound is AVAILABLE, then the last resort is to simply create a key, by assigning a unique number to each record or OCCURRENCE. Then this is known as developing an artificial key. Compound Key: If no single data element uniquely identifies occurrences within a construct, then combining multiple elements to create a unique identifier for the construct is known as creating a compound key. Natural Key: When one of the data elements stored within a construct is utilized as the primary key, then it is called the natural key.

What Are Best Graduate Schools For Ai? |
|
Answer» The short ANSWER is: MIT, CMU, and Stanford are HISTORICALLY the POWERHOUSES of AI and still are the top 3 today. There are however, hundreds of SCHOOLS all over the world with at least one or two active researchers doing interesting work in AI. What is most important in graduate school is finding an advisor who is doing something YOU are interested in. Read about what's going on in the field and then identify the the people in the field that are doing that research you find most interesting. If a PROFESSOR and his students are publishing frequently, then that should be a place to consider.

What Is The Difference Between Classical Ai And Statistical Ai? |
|
Answer» Statistical AI, arising from MACHINE learning, tends to be more concerned with "inductive" thought: given a set of patterns, induce the trend. CLASSICAL AI, on the other hand, is more concerned with "deductive" thought: given a set of constraints, deduce a CONCLUSION. ANOTHER difference, as mentioned in the previous question, is that C++ tends to be a favorite language for statistical AI while LISP dominates in classical AI. A SYSTEM can't be truly intelligent without displaying properties of both inductive and deductive thought. This lends many to believe that in the end, there will be some kind of synthesis of statistical and classical AI.

What Are Good Programming Languages For Ai? |
|
Answer» This topic can be somewhat sensitive, so I'll probably tread on a few toes, please forgive me. There is no authoritative answer for this question, as it really depends on what languages you like programming in. AI programs have been written in just about every language ever created. The most common seem to be Lisp, PROLOG, C/C++, recently Java, and even more recently, Python. LISP: For many years, AI was done as research in universities and laboratories, thus fast prototyping was favored over fast execution. This is ONE reason why AI has favored high-level languages such as Lisp. This tradition means that current AI Lisp programmers can draw on many resources from the community. Features of the language that are good for AI programming include: garbage collection, dynamic TYPING, functions as data, uniform syntax, interactive environment, and extensibility. READ Paul Graham's essay, "BEATING the Averages" for a discussion of some serious advantages: PROLOG: This language wins 'cool idea' competition. It wasn't until the 70s that people began to realize that a set of logical statements plus a general theorem prover could make up a program. Prolog combines the high-level and traditional advantages of Lisp with a built-in unifier, which is particularly useful in AI. Prolog seems to be good for problems in which logic is intimately involved, or whose solutions have a succinct logical characterization. Its major drawback (IMHO) This topic can be somewhat sensitive, so I'll probably tread on a few toes, please forgive me.

Answer» There are many, some are 'problems' and some are 'techniques'. Automatic Programming: The task of describing what a program should do and having the AI system 'write' the program. Bayesian Networks: A technique of structuring and conferencing with probabilistic INFORMATION. (Part of the "machine learning" problem). Constraint Satisfaction: solving NP-complete problems, using a variety of techniques. Knowledge Engineering/Representation: turning what we know about PARTICULAR domain into a form in which a computer can understand it. Machine Learning: Programs that learn from EXPERIENCE or data. Natural Language Processing(NLP): Processing and (perhaps) understanding human ("natural") language. Also known as computational linguistics. Neural Networks(NN): The study of programs that function in a manner similar to how animal brains do. Planning: given a set of actions, a goal state, and a PRESENT state, decide which actions must be taken so that the present state is turned into the goal state Robotics: The intersection of AI and robotics, this field tries to get (usually mobile) robots to ACT intelligently. Speech Recognition: Conversion of speech into text. There are many, some are 'problems' and some are 'techniques'.

What Has Ai Accomplished? |
|
Answer» Quite a bit, actually. In 'Computing machinery and intelligence.', Alan Turing, one of the founders of computer science, made the claim that by the year 2000, computers WOULD be able to pass the Turing test at a REASONABLY sophisticated level, in particular, that the average interrogator would not be able to identify the computer correctly more than 70 per cent of the TIME after a five minute CONVERSATION. AI hasn't quite lived upto Turing's claims, but quite a bit of progress has been made, including:

I Am A Programmer Interested In Ai. I Am Writing A Game That Needs Ai. Where Do I Start? |
|
Answer» It depends what the game does. If it's a two-player board game,LOOK into the "Mini-max" search algorithm for games. In most commercial games, the AI is is a combination of high-level scripts and low-level efficiently-coded, real-time, rule-based systems. Often, commercial games tend to use finite state machines for computer players. Recently, discrete Markov models have been used to simulate unpredictible human players (the buzzword compliant name being "fuzzy" finite state machines). A RECENT popular game, "Black and White", used MACHINE LEARNING TECHNIQUES for the non-human controlled characters. Basic reinforcement learning, perceptrons and decision trees were all parts of the learning system. It depends what the game does.

What Is The Difference Between Strong Ai And Weak Ai? |
|
Answer» Strong AI makes the bold claim that computers can be made to think on a level (at LEAST) equal to humans. Weak AI simply states that some "thinking-like" features can be added to computers to make them more useful tools... and this has already started to happen (witness expert SYSTEMS, drive-by-wire cars and speech RECOGNITION software). What does 'think' and 'thinking-like' mean? That's a matter of MUCH debate. Strong AI makes the bold claim that computers can be made to think on a level (at least) equal to humans.
