Many clustering problems in Computer Vision group data points that are the result of statistical estimation and these data points can have a great amount of uncertainty. Motion segmentation by clustering of optical flow is such an example because very often optical flow cannot be estimated without significant uncertainty. We present a EM based clustering algorithm for incomplete data and we app...

Clustering groups items together that are most similar to each other and sets those that are least similar into different clusters. Methods have been developed to cluster records in a data set that are of only qualitative or quantitative data. Data sets exist that contain a mix of qualitative (nominal and ordinal) and quantitative (discrete and continuous) data. Clustering records of mixed kind...

In this paper we make use of counterpart semantics to prove an original incompleteness result in quantified modal logic (QML), that is, the system QE .K+BF based on free logic and containing the Barcan formula is incomplete with respect to Kripke semantics. This incompleteness result extends to the system QE .K+CBF+BF obtained by adding the converse of the Barcan formula to QE .K+BF .

Most research on panel data focuses mean or quantile regression, while there is not much about regression methods based the mode. In this paper, we propose a new model named fixed effects modal for in which how conditional mode of response variable depends covariates and employ kernel-based objective function to simplify computation. The proposed can complement regressions provide better centra...

Rumor spreaders are increasingly utilizing multimedia content to attract the attention and trust of news consumers. Though quite a few rumor detection models have exploited multi-modal data, they seldom consider inconsistent semantics between images texts, rarely spot inconsistency among post contents background knowledge. In addition, commonly assume completeness multiple modalities thus incap...

the present paper sets out to investigate the syntactic category of persian modals, šâyad ‘perhaps’ and bâyad ‘must’. the syntactic category of the two modal elements has been viewed differently by different scholars. a number of scholars argue that both šâyad and bâyad are modal auxiliaries, while others claim that they both are modal adverbs. we propose that šâyad is a modal adverb and bâyad ...
