I had assumed that if there was progress, I would have heard about it with the same ferocity as the original round of advertisements. I did not mean to imply that expert systems are wrong, or are bad. They seem quite viable, now that there is more ram, disk and compute power. Algos can dig deeper, explore more branches, find and resolve more inconsistencies. The Jeopardy tournament clearly proved that. Historically, the systems were incapable of "learning from experience" but tighter coupling to experiential systems might solve that. Whether or not a suitcase fits in a trophy, or the other way around depends on one's experience with trophies and suitcases; to have experience with either, you have to be a human (with a need move items, and a interest in trophy-granting activities (and a suitcase in a closet, and experience with places that have closets or attics ...)) Common sense is experiential; something you develop over decades of interacting with a reactive environment. My critique of Doug Lenat is that perhaps he underestimated the magnitude of the task,and pinned too much hope on "microtheories" to resolve deductive inconsistencies. There is an open question: is it better to curate an existing knowledge-base, slowly expanding it, or is it better to create a more robust learning system, that will be able to rapidly acquire the needed knowledge once it's turned on? I'm betting on the latter, not the former. --linas -- cassette tapes - analog TV - film cameras - you ------------------------------------------ Artificial General Intelligence List: AGI Permalink: https://agi.topicbox.com/groups/agi/T9ccd0aac7d42f57b-Mc35779562939e86903d7ad66 Delivery options: https://agi.topicbox.com/groups/agi/subscription
