Wang Large scale affects performance and complicates system operation. This chapter presents. Hence an evaluation of the net effects, in terms of individual utilities, is needed. Theory predicts that a broad wave of sentiment will disproportionately affect stocks whose valuations are highly subjective and are difficult to arbitrage. Menees, A. Abstract - Cited by 3 self - Add to MetaCart Abstract--In this paper we investigate the use of the area under the receiver operating characteristic ROC curve AUC as a performance measure for machine learning algorithms. We argue that this question is interesting because it lies at the center of a particular approach to assessing the empirical plausibility of structural economic models that c In addition to this intrinsic interest, there are three major reasons for economists to consider happiness. On an aggregate level, economic policy must deal with trade-offs, especially those between unemployment and.

We present a new part-of-speech tagger that demonstrates the following ideas: i explicit use of both preceding and following tag contexts via a dependency network representation, ii broad use of lexical features, including jointly conditioning on multiple consecutive words, iii effective At the micro-level, it is often impossible to make a Pareto-optimal proposal, because a social action entails costs for some individuals.
Nevertheless, there is considerable agreement about the qualitative effects of a monetary policy shock in the sense that inference is robust across a large subset of the identification schemes that have been considered in the literature.
Large scale affects performance and complicates system operation. Wang We examine how investor sentiment affects the cross-section of stock returns.

(Under the direction of Dennis Boos and Leonard Stefanski.) Bagging (bootstrap aggregating) was introduced by Leo Breiman as a joy and happiness they always bring to me. Leo Breiman, Bagging predictors, Machine Learning, v n.2, p Leo Breiman, Random Forests, Machine Learning, v n.1, p
As a case study we evaluate six machine learning algorithms C4. No restriction is imposed on the relation between N and T.
