Many Internet functions, such as QoS and security, require classification of each packet based on a set of rules. As Internet bandwidth and data transmission rates continue to grow, the available time budget to classify ...

Receiver Operator Characteristic (ROC) curves and Precision-Recall (PR) curves are commonly used to present results for binary decision problems in machine learning. When the class distribution is close to being uniform, ...

Entity matching (a.k.a. record linkage) plays a crucial role in integrating multiple data sources, and numerous matching solutions have been developed. However, the solutions have largely exploited only information available ...

Database catalogs often do not contain enough statistical information to correctly cost all possible physi-cal plans. In their absence, the optimizer can produce incorrect estimates and select suboptimal plans for execution. ...

This paper describes new strategies (involving active recruiting and peer-led team learning) for encouraging women and minority students to enroll in introductory computer science courses, and to go on to major or minor ...

There are few runtime tools for modestly sized computing systems, with 10^3 processors, and above this scale, they work poorly. We present the Stack Trace Analysis Tool (STAT) to aid in debugging extreme-scale applications. ...

Virtual machine technology is becoming an increasingly popular vehicle for enabling process and service migration. Many migration frameworks rely on a distributed file system to avoid worrying about the burden of migrating ...

Understanding and managing complex computer systems is quickly becoming intractable for an unaided administrator. Questions about how to provision server and distributed systems or how workload changes will affect system ...

Recently, Sagiv, Reps, and Wilhelm introduced a powerful abstract-interpretation framework for program analysis based on three-valued logic [84]. Instantiations of this framework have been used to show a number of interesting ...

A Process Virtual Machine (VM) provides an execution environment for a guest user application program on a host platform that may differ from the guest's native platform. Informally, virtualization is compatible if there ...
