Learning Finite Automata Using Local Distinguishing Experiments
One of the open problems listed in Rivest and Schapire is whether and how that the copies of L in their algorithm can be com bined into one for better performance This paper describes an algorithm called D that does that combination The idea is to represent the states of the learned model using observable symbols as well as hidden symbols that are con structed during learning These hidden sym b...
متن کاملLocal/Global Phenomena in Geometrically Generated Graphs
In recent years, a wealth of random graph models have arisen to explain the power-law degree distribution observed in the Internet [1] and other complex networks (see, for example, [6] and [8]). While power-law behavior often drives these models, less is known about other very natural properties found in complex networks. One such notion is the local versus global structure of a network. In [12...
متن کاملReconstructing finite group actions and characters from subgroup information
Holroyd, F.C., Reconstructing finite group actions and characters from subgroup information, Discrete Mathematics 110 (1992) 283-287. A finite group G is said to be action reconstructible if, for any action of G on a finite set, the numbers of orbits under restriction to each subgroup always give enough information to reconstruct the action up to equivalence. G is character reconstructible if, ...
متن کاملModelling local and global phenomena with sparse Gaussian processes
Much recent work has concerned sparse approximations to speed up the Gaussian process regression from the unfavorable O(n) scaling in computational time to O(nm). Thus far, work has concentrated on models with one covariance function. However, in many practical situations additive models with multiple covariance functions may perform better, since the data may contain both long and short length...

Let E be an elliptic curve over Q with complex multiplication by the ring of integers of an imaginary quadratic eld. Let be the Hecke character associated to E by the theory of complex multiplication. Let be the complex conjugate character of. For a pair of integers k and j, deene the Hecke character ' = '(k; j) = k j. Let p be a prime where E has good, ordinary reduction. Let p be a xed prime ...
