Conditional Random Fields (CRFs) are the state-of-the-art models for sequential labeling problems. A critical step is to select optimal feature template subset before employing CRFs, which is a tedious task. To improve the efficienc y of t his step, we propose a new method that adopts the maximum entropy (ME) model and maximum entropy Markov models (MEMMs) instead of CRFs considering the homolo...

We investigate the problem of designing efficient multiplex PCR for medical applications. We show that the problem is NP-complete by transformation to the Multiple Choice Matching problem and give an efficient approximation algorithm. We developed this algorithm in a computer program that predicts which genomic regions may be simultaneously amplified by PCR. Practical use of the software shows ...

In this paper we investigate the communication performance of three high end supercomputers from the National Energy Research Scientific Computing Center (NERSC), and discover which machine allows for the optimal scaling for the large scale, scientific code PARSEC. Our first step is to discover the relevant message passing function calls that PARSEC makes use of so that we can test appropriate ...

We consider the problem of choosing the optimal (in the sense of mean-squared prediction error) multistep predictor for an autoregres-sive (AR) process of finite but unknown order. If a working AR model (which is possibly misspecified) is adopted for multistep predictions, then two competing types of multistep predictors (i.e., plug-in and direct predictors) can be obtained from this model. We ...

Web services are modular applications that can be described, located and invoked on the Internet. A user request may not only correspond to one specific service, but also to a set of web services. Thus, it is necessary that a composition of services be done in order to obtain the expected result. Nonetheless, many services with the same goal but different characteristics can be discovered. Inde...

Optimal Incentives in Core-Selecting Auctions Robert Day, School of Business, University of Connecticut Paul Milgrom, Dept of Economics, Stanford University August 25, 2010 Auctions that select core allocations with respect to reported values generate competitive levels of sales revenues at equilibrium and limit bidder incentives to use shills. Among core-selecting auctions, the ones that selec...

Unique Indigenous cultures have become increasingly attractive and prevalent in the tourism market. More more tribes wish to improve their economic situation by developing a industry with ethnic culture as core attraction. The main arguments regarding involve cultural vicissitudes between past present, indicating that appropriate development conservation should be carried out. As features are c...
