Introducing a family of linear measures for feature selection in text categorization
TL;DR: This paper proposes to select relevant features by means of a family of linear filtering measures which are simpler than the usual measures applied for this purpose and finds that the proposed measures perform better than the existing ones.
Journal ArticleDOI
Scoring and selecting terms for text categorization
TL;DR: A set of (machine learning) ML-based scoring measures for conducting feature selection by analyzing which measure obtains the best overall classification performance in terms of properties such as precision and recall.
Journal ArticleDOI
An entropy measure definition for finite interval-valued hesitant fuzzy sets
TL;DR: From this definition, several results have been developed for each mapping that shapes the entropy measure in order to get such functions with ease, and as a consequence, allowing to obtain this new entropy in a simpler way.
Journal ArticleDOI
Improving performance of text categorization by combining filtering and support vector machines
TL;DR: This report tries to prove that a previous filtering of the words used by SVM in the classification can improve the overall performance, and shows that filtering significantly improves the recall of the method, and that also has the effect of significantly improving theOverall performance.

TL;DR: To test the existence of an endogenous pacemaker in human placenta, the expression of circadian locomoter output cycles kaput (Clock), brain and muscle arnt-like (Bmal)1, period (Per)2, and cryptochrome (Cry)1 mRNAs are studied, allowing us to suggest that a peripheral oscillator exists in human Placenta.
