Move prediction systems have always been part of strong Go programs. Recent research has revealed that taking interactions between features into account improves the performance of move predictions. In this paper, a factorization model is applied and a supervised learning algorithm, Latent Factor Ranking (LFR), which enables to consider these interactions, is introduced. Its superiority will be...

A lone pilot assisted CDMA system is capable of separating the interference components included in a received input by solving a simultaneous equation. This real performance, however, depends on the property of the lone pilot response matrix which is given by the user spreading sequences and the multipath conditions. Consequently, it does not work well whenever the matrix has a wrong property. ...

There is considerable forensic import to the hypothesis that the quality of an eyewitness' description of a face is useful for predicting the accuracy of a subsequent identification. Although previous studies have failed to support this hypothesis, those studies were designed to test only whether witnesses who are good describers also are good identifiers. The current study used 88 different ta...

Korean has two syntactic constructions expressing negation. Examples of the two types of negation, which I will refer to as “Short Form” and “Long Form,” are given in (2) and (3). Short Form negation involves adding a negative prefix anto the verbal complex. The Short Form negated sentence in (2) differs from the affirmative sentence in (1) only in the underlined morpheme. Long Form negation, s...

A computer system is described that provides a real-time musical accompaniment for a live soloist in a piece of non-improvised music. A Bayesian belief network is developed that represents the joint distribution on the times at which the solo and accompaniment notes are played as well as many hidden variables. The network models several important sources of information including the information...

Random forests are a very effective and commonly used statistical method, but their full theoretical analysis is still an open problem. As a first step, simplified models such as purely random forests have been introduced, in order to shed light on the good performance of random forests. In this paper, we study the approximation error (the bias) of some purely random forest models in a regressi...

Plural nouns do not strictly refer to more than one object, which suggests that they are not semantically marked to mean “more than one” and that plurality inferences are made via a scalar implicature. Consistent with that hypothesis, recent evidence using a picture-matching paradigm supports founds that participants were equally fast to respond to a picture of a single object as a picture of m...

Our approach to the Log Analysis for Digital Societies (LADS) task of LogCLEF 2009 is to define three different levels of performance: success, failure and strong failure. To investigate the log files we adopt qualitative and quantitative methods. In a more qualitative approach we attempt to identify intercultural differences in user patterns by visualizing the user interactions with The Europe...
