OBE: Outlier by Example

Outlier detection in large datasets is an important problem. There are several recent approaches that employ very reasonable definitions of an outlier. However, a fundamental issue is that the notion of which objects are outliers typically varies between users or, even, datasets. In this paper, we present a novel solution to this problem, by bringing users into the loop. Our OBE (Outlier By Exa...

A Multiprocessor Implementation of Joyce

Joyce is a programming language for parallel computers based on CSP and Pas-cal. A Joyce program defines concurrent agents which communicate through unbuffered channels. This paper describes a multiprocessor implementation of Joyce.

Family Planning Perspectives Through the mid-1980s, Medicaid eligibility requirements included very low income thresholds established by the individual states. Between 1987 and 1991, eligibility standards for poor and near-poor pregnant women were expanded dramatically. The 1986 Omnibus Budget and Reconciliation Act (OBRA) permitted states to extend eligibility (and receive reimbursement for se...

Joyce - A Programming Language for Distributed Systems

This paper describes a secure programming language called Joyce based on CSP and Pascal. Joyce permits unbounded (recursive) activation of communicating agents. The agents exchange messages through synchronous channels. A channel can transfer messages of different types between two or more agents. A compiler can check message types and ensure that agents use disjoint sets of variables only. The...
