"Sony Researchers Create 'Curious' Aibos"
IDG News Service (06/14/05); Kallender, Paul
Researchers at the Sony Computer Science Laboratory in Paris have announced the possible creation of synthetic curiosity in the form of the Aibo ERS-7 robot dog. Advances in computing power have led to systems that appear to have the ability to react based on pre-programmed, task-defined algorithms, but these devices can only act within a given set of parameters. The Sony researchers, however, have equipped Aibo with a "metabrain" algorithm that continually forces a learning algorithm to look for new and more challenging tasks and to abandon tasks that do not appear to lead anywhere, in essence creating virtual boredom, curiosity, and a desire to learn. In repeated experiments, various Aibos, after being placed in play pens with balls, learned progressively to swivel their legs and heads, wiggle, crawl, and crawl and hit and follow a ball placed in front of them despite not being programmed to do so. "What we have done is give Aibo an ability to have its learning defined by the quality of learning," explains researcher Pierre-Yves Oudeyer. "So it's learning to classify its sensory space and progressively structure that space." The researchers admit that giving Aibo the cognitive intelligence comparable of even a two-month-old human infant will be difficult.
