Abstract
We consider inductive inference with limited memory[1].
We show that there exists a set U of total recursive functions such that
-
U can be learned with linear long-term memory (and no short-term memory);
-
U can be learned with logarithmic long-term memory (and some amount of short-term memory);
-
if U is learned with sublinear long-term memory, then the short-term memory exceeds arbitrary recursive function.
Thus an open problem posed by Freivalds, Kinber and Smith[1] is solved. To prove our result, we use Kolmogorov complexity.
