Learning Using Local Membership Queries
We introduce a new model of membership query (MQ) learning, where the learning algorithm is restricted to query points that are close to random examples drawn from the underlying distribution. The learning model is intermediate between the PAC model (Valiant, 1984) and the PAC+MQ model (where the queries are allowed to be arbitrary points). Membership query algorithms are not popular among mach...
متن کاملOn Using Extended Statistical Queries to Avoid Membership Queries
The Kushilevitz-Mansour (KM) algorithm is an algorithm that finds all the “large” Fourier coefficients of a Boolean function. It is the main tool for learning decision trees and DNF expressions in the PAC model with respect to the uniform distribution. The algorithm requires access to the membership query (MQ) oracle. The access is often unavailable in learning applications and thus the KM algo...
متن کاملLearning Using 1-Local Membership Queries
Classic machine learning algorithms learn from labelled examples. For example, to design a machine translation system, a typical training set will consist of English sentences and their translation to French. There is a stronger model, in which the algorithm can also query for labels of new examples it creates. E.g, in the translation task, the algorithm can create a new English sentence, and r...
متن کاملMultidimensional Membership Queries for Temporal Databases
Consider a dynamic set of multidimensional objects S, that evolves over time. A temporal membership query asks whether an object with given key attributes was in the set S at some time t. This paper provides efficient solutions to this temporal query. In particular, we present partially persistent extensions to (i) a hashing based scheme the BANG file and (ii) the hB -tree. The performance of b...
