LONDON (Reuter) — Whirring about the floor of Queen Mary College artificial intelligence unit is a robot hungry for power, learning to think for itself, Junior, lacking the charisma of automatons in current science fiction films, is a threewheeled mess of wires, batteries and steel struts with a ro- tating camera mounted on top. That's his body. His brain is the university’s lange IC 1904s computer and a smaller micro- processor to which he is connected by radio. Most expensive computerized technology is designed for specific jobs. Junior’s only purpose is to learn, by trial and error, about getting along in his envi- ronment. . For instance, the charge level of Junior’s batteries ranges from high, through bungry and low to extremely low. PAGE 12, THE HERALD, Wednesday, May 3, 1978 Junior makes a strange student High has been programmed to equal pleasure and low to equal ain. When Junior is ungry, he emits an electronic crying sound. HE RECHARGES HIMSELF When he is hungry, says project leader Alan Bond, Junior “goes off looking for a high.’ He must locate and hook himself up to the recharging point in the lab to avoid a low. Scientists who spawned him didn’t give Junior rouch information to go on, bul they did give him a system by which he stores his experiences and learns to predict what is going- to happen next by putting two or more past experiences together. The validity of such predictions allows him to attach numerical significance to what he learns. Thus irrelevant his = en- things in eventually vironment, are given zero signifc- cance and forgotten. Bond said it is hard not to talk about Junior as though he were a person. He speaks of Junior's ‘consciousness,’ — the buffer in which all his ex- periences are stored. “To a normal person it acts like a litle animal,” said Bond, carefully distinguishing normal persons from scientists. He noted that Swiss ychologist Jean Piaget elieves that infants learn by noting repeated sequences—crying —_fal- lowed by food, for example, Junior is designed to learn the same way. HEAD CAN EXAMINED “Rut with a child, you cannot look inside . its head and see what it is learning,’ said research assistant Philip Marks. “We can dump out Junior's pattern and see what he ts learning at any BE time,’” Besides feeding him- self, Junior is also told to do other jobs, such as finding a cross painted on he val and moving next it: Eventually he will have all human senses except smeil, and Marks said he believes Junior can develop the. reasoning power of some animals, such as rats. Bond disagrees: ‘“‘It is hard to compare ar- tificial and natural in- telligence. Rats are pretty smart, while ar- tificial intelligences can do some stupid things.” The team working with Junior includes computer scientists, interested in computer _ intelligence, and biologists studying ideas about natural in- telligence, 1925 — John Scopes, who had been arrested for teaching the theory of evolution, went on trial at Dayton, Tenn. 4 BUSINESS DIRECTORY R E NTALS L¥D.
