We propose a method of generating teaching policies for use in intelligent tutoring systems (ITS) for concept learning tasks [37], e.g., teaching students the meanings of words by showing images that exemplify their meanings à la Rosetta Stone [30] and Duo Lingo [13]. The approach is grounded in control theory and capitalizes on recent work by [28], [29] that frames the “teaching” problem as th...

Moslehian  and Mirmostafaee, investigated the fuzzystability problems for the Cauchy additive functional equation, the Jensen additivefunctional equation and the cubic functional equation in fuzzyBanach spaces. In this paper, we investigate thegeneralized Hyers–-Ulam--Rassias stability of the generalizedadditive functional equation with $n$--variables, in fuzzy Banachspaces. Also, we will show ...

The relative commutant A∩A of a strongly self-absorbing algebra A is indistinguishable from its ultrapower A . This applies both to the case when A is the hyperfinite II1 factor and to the case when it is a strongly self-absorbing C-algebra. In the latter case we prove analogous results for l∞(A)/c0(A) and reduced powers corresponding to other filters on N. Examples of algebras with approximate...
