It is here, again that >AI (especially in relation to intelligent data bases) may come to the rescue. Along with the need to handle increasing amounts of information, comes an increased need for performance: Timeliness -- the speed at which information must be processed has increased dramatically. (e.g. computer console messages in a commercial datacenter with multiple CPUs need to be analyzed at the rates of 5 to 50 per SECOND. ) Accuracy -- decisions must be made at accuracies that are beyond the sustained ability of human experts (e.g process control systems needing 0.1% accuracy in set point values for hundreds of variables set every minute for 24 hrs/day) Cost -- expert knowledge must be employed in situations where the presence of experts can't be afforded (e.g. stock or commodity trading systems based on expert systems and/or neural nets) Availability- most experts are fond of their weekends and evenings, and make a very big deal over their vacations. AI methods can make their skills available 24 hrs, 365 days/year. I have surveyed many companies in their use of AI techniques. My personal feeling, supported by no one else at this point, is that the "why" of AI will be answered when the following application is implemented and becomes widespread: A mid level manager must analyze a budget report once a week. He uses the rules he follows as the basis for an expert system: "If the variance is greater than $1000 in Acct 101, OR the TOTAL in Line 5 is greater than 10% of plan, OR ... " an then delegates the expert system and his rule base of 10, 15, or 20 rules to HIS SECRETARY, AI and expert systems will have come of age in industry. The big question will be answered not by robotics applications, or speaker independent speech recognition, or writer-independent character recognition, or even smart data bases. (Most professionals don't use data bases), but by simple tasks, done by almost everyone in the work environment, taken over or delegated to someone else as a result of AI. The AI applications that do that will propogate across the workplace like LOTUS or other truly horizontal applications.

I agree that this is serious and that AI, as an inherently interdisciplinary field, has the potential to pull areas together. However, there is tremendous pressure within the academic community to encourge and reward *focused* efforts in a narrow area, at least until you become a tenured old-sage :-) It's very time consuming to keep up with multiple fields to any real depth but even as you look for synergy you hear your advisor saying, "It won't get published if the the editors don't have a department for it..." Even when there is a department, it is suggested that you remove the excess (other disciplines) to make it more relevent or accessible to the regular readership. I think it's worth the effort, but it would certainly help if it weren't such an uphill struggle. -David ----------------- David Perry Greene GSIA dg1v@andrew.cmu.edu Carnegie Mellon University "You're welcome to use my oppinions, just don't get them all wrinkled." ------------------------------ Date: 19 Sep 88 06:59:52 GMT From: TAURUS.BITNET!shani@ucbvax.berkeley.edu Subject: Re: Why?

What is it that you would have > an intelligent machine do? Well, well waddaya know! :-) Not long ago, an endless argument was held in this newsgroup, reguarding AI and value-systems. It seem that the reason this argument did not (as far as I know) reach any constructive conclousions, is that the question above was never raised... So realy? what do we expect an intelligent machine to be like? Or let me sharp the question a bit: How will we know that a machine is intelligent, if we lack the means to measure (or even to define) intelligence ? This may sound a bit cynical, but it is my opinion that setting up such misty goals, and useing therms like 'intelligence' or 'value-systems' to describe them, is mainly ment to fund something which MAY BE beneficial (since research is allmost always beneficial in some way), but will never reach those goals... why who would like to fund a research which will only end up with easyer to use programming languages or faster computers? O.S. BTW: I wish it wasn't like that. It could be wonderful if RND financing was not goal-depended... all and all, the important thing is the research itself. ------------------------------ Date: 21 Sep 88 20:32:10 GMT From: quintus!certes!jeff2@unix.sri.com ( jeff) Subject: Re: Why? in article <867@taurus.BITNET>, shani@TAURUS.BITNET says: > > In article <6823@uwmcsd1.UUCP>, markh@csd4.milw.wisc.edu.BITNET writes: >> Why does anyone want artificial intelligence? >> >> What is it that you're seeking to gain by it?

At least two people are required to automate some portion of a task; one to describe the process and one to automate it; this increases the cost of the automation process (two salaries are being paid to do one job), and limits the number of tasks that can be automated at any one time to the number of automaters available. As a result, the number of tasks to be automated is expanding much more rapidly than the number of people to automate it. Given that few automaters remain experts in their field long enough to be fully replaced, we have no choice but to reduce the skill level required to automate a task if we want to improve our abilities to automate tasks. This alone is justification for research into "easy to use" languages. Additionally, it would be nice if AI could create a tool for the development of the other automation tools that are sufficiently close to those in current use (e.g. English) that little training is required to use them. -- /*---------------------------------------------------------------------------*/ Jeff Griffith Teradyne/Attain, Inc., San Jose, CA 95131 (408)434-0822 Disclaimer: The views expressed here are strictly my own.
