Unachievable Region in Precision-Recall Space and Its Effect on Empirical Evaluation
(University of Wisconsin-Madison Department of Computer Sciences, 2012-05-30)Precision-recall (PR) curves and the areas under them are widely used to summarize machine learning results, especially for data sets exhibiting class skew. They are often used analogously to ROC curves and the area under ... -
Unconstrained Lagrangians in Nonlinear Programming
(University of Wisconsin-Madison Department of Computer Sciences, 1974)The main purpose of this work is to associate a wide class of Lagrangian functions with a nonconvex, inequality and equality constrained optimization problem in such a way that unconstrained stationary points and local ... -

Understanding and Exploiting Network Traffic Redundancy
(University of Wisconsin-Madison Department of Computer Sciences, 2007)The Internet carries a vast amount and a wide range of content. Some of this content is more popular, and accessed more frequently, than others. The popularity of content could be quite ephemeral - e.g., a Web flash ... -
Understanding Representation Learning Paradigms with Applications to Low Resource Text Classification
(2020-05-21)A crucial component of modern machine learning systems is learning input representations which can be used for prediction tasks. The expensive cost of labelling and easy availability of unlabelled data has led to the ... -
Understanding the World's Worst Spamming Botnet
(University of Wisconsin-Madison Department of Computer Sciences, 2009)On November 11, 2008, the primary web hosting company, McColo, for the command and control servers of Srizbi botnet was shutdown by its upstream ISPs. Subsequent reports claimed that the volume of spam dropped significantly ... -
A Unified Approach to Logic Program Evaluation
(University of Wisconsin-Madison Department of Computer Sciences, 1989)The Prolog evaluation algorithm has become the standard for logic program evaluation, and bottom-up methods have long been considered impractical because they compute irrelevant facts. Recently, however, bottom-up evaluation ... -
A Unified Formalization of Four Shared-Memory Models

Uniqueness of Solution in Linear Programming
(University of Wisconsin-Madison Department of Computer Sciences, 1978)A number of characterizations are given which are both necessary and sufficient for the uniqueness of a solution to a linear programming problem. -
Uniqueness of the Maximal Extension of a Monotone Operator

Upper Bounds on the Complexity of Space Bounded Interactive Proofs
(University of Wisconsin-Madison Department of Computer Sciences, 1989)We show that the class IP(2pfa) of languages accepted by interactive proof systems with finite state verifiers is contained in ATIME(2 2o(n)). We also show that 2-prover interactive proof systems with finite state verifiers ... -
