computing / technology: artificial intelligence

Overview

The endeavor to create artificial intelligence (AI) via electronic computational methods, which is generally agreed to have begun in the 1950s, has turned out to be considerably more difficult than originally imagined.

Partly as a result of this, the field has split into areas whose goals vary in their reach:

  • narrow AI generally refers to carefully-written programs which seem to respond with a certain amount of intelligence in certain narrowly-defined areas; "programs that solve particular, highly specialized types of problems" (2007-10-18 KA).
  • general AI refers to what we more commonly think of as "intelligence", i.e. the ability to solve new types of problems; adaptability, flexibility; "programs with the autonomy and self-understandings to come to grips with novel problem domains and hence solve a wide variety of problem types" (2007-10-18 KA).

Early attempts suffered greatly from lack of computational power; Moore's Law (which more or less doubles available CPU power in several measurable ways every 1.5 years or so) has now vastly increased the available power, and the best estimates are that an average desktop PC will possess approximately the computing power of a human brain sometime before 2030. What remains is to create the software to allow it to think like one.

Efforts have been focused in a number of areas:

  • scripted conversational strategies, e.g. AIML
  • "common sense" engines, mainly Cyc
  • artificial neural networks (these seem to have fallen out of favor, but nonetheless showed great promise as a tool)

Projects

  • A.L.I.C.E. Artificial Intelligence Foundation: development of scripted conversational AI using Artificial Intelligence Markup Language (AIML): shows potential for adaptivity if combined with other AI tools. The main problem with allowing the engine to "learn" from interactive users is the "trust" issue; this will probably require the development of a social skills engine, i.e. keeping track of who tells the AI what, correlating individuals with corroboration of facts received, and deciding when there is enough corroboration to accept received information as "fact" (and how to do so, i.e. how should the AI remember that this is a "new" fact, with perhaps some indication of where it came from?)
  • Artificial General Intelligence Research Institute (AGIRI) (wiki)
  • CALO "Cognitive Assistant that Learns and Organizes" "learns by interacting with and being advised by its users, will handle a broad range of interrelated decision-making tasks that have in the past been resistant to automation. A CALO will have the capability to engage in and lead routine tasks, and to assist when the unexpected happens. To focus the research on real problems and ensure the software meets requirements such as privacy, security, and trust, the CALO project researchers themselves are using the technology during its development." (3-year project ends 2009-07-31; was part of DARPA's PAL project)
  • Cognitive Code Corporation's SILVIA technology sounds suspiciously like a proprietary implementation of an AIML engine...
  • The "Dexter" robot:
  • 2007-06-01 CB2 robot:
  • Cyc: open-source project to develop "common sense" software
  • PARC natural language processing: apparently some of this technology is being used in PowerSet
