There is a growing interest in automatically building opinion lexicon from sources such as product reviews. Most of these methods depend on abundant external resources such as WordNet, which limits the applicability of these methods. Unsupervised or semi-supervised learning provides an optional solution to multilingual opinion lexicon extraction. However, the datasets are imbalanced in differen...

With the widespread popularity of mobile terminals in Internet Things (IoT), demand for cross-domain access between different regions has also increased significantly. The nature wireless communication media makes vulnerable to security threats access. Identity authentication is a prerequisite secure data transmission cross-domain, and it first step guarantee credibility sources. Most existing ...

the purpose of this study is to investigate the relationshipbetween the mutual funds flows and the return of stock index using 65mutual funds in the period of 2008 to 2011.in this study, the dailychanges of the total number of units of mutual funds and the changesof the total values of units of mutual funds were considered as acriteria for the net of mutual funds flows. the results of johansen ...

The two main stylized facts in the mutual fund literature are that funds exhibit little ability to persistently outperform their peers, but that new money flows into funds with the highest past returns. The traditional interpretation is that fund managers are unskilled and fund investors are unsophisticated. Berk and Green (2004) offer an alternative, arguing that more-skilled managers will man...

In recent years, the popularity of wireless inductive power transfer (WIPT) system for electric vehicle battery charging (EVBC) is always ever-increasing. In the WIPT inductively coupled coil structure is the heart of the system and the mutual inductance (MI) between the coupled coils is the key factor for effective power transfer. This paper presents the analysis of mutual inductance between t...

In this contribution we present new conditions on cross cumulants which guarantee that blind source separation has been performed , and we relate these conditions to the maximization of mutual information as a criterion for ICA.

This paper …nds that fund herding, de…ned as the tendency of a mutual fund to follow past aggregate institutional trades, is an important predictor of mutual fund performance. Examining actively managed U.S. equity mutual funds over the period 1990-2009, we …nd that funds with a higher herding tendency achieve lower future returns. The performance gap between herding and antiherding funds is pe...

A comparative analysis of the efficiency of correlation (cross-correlation, Tanimoto coefficient and Kendall's rank correlation coefficient) and information (mutual information of Tsallis and Shannon, F-information measure and entropy of the joint probability distribution) measures of image similarity for the synthesis of recursive estimation algorithms is presented for the problem of estimatin...
