Subsequent tests of our data-induced flying model have b roadly confirmed the re p o rt e d results but have also identified a lack of robustness. We had undere s t i m a t e d the latter and now re g a rd our re p o rt (Michie and Camacho 1994) as being, by omission, potentially misleading. Successes and shortcomings of behavioral cloning (l e a rning by imitation) have been reviewed by Urbancic and Bratko (1994). They discuss the following problem domains: p o l e - a n d - c a rt balancing (Michie, Bain, and Michie 1990; Chambers and Michie 1969), flight-simulator c o n t rol (Sammut et al. 1992), telephone-line scheduling (Kibira 1993), and crane-simulator control (Urbancic and Bratko 1994). Conclusions a re as follows: First, successful clones have been induced using standard ML techniques in all four domains.
