Feature selection for high-dimensional data: a fast correlation-based filter solution

by Lei Yu, Huan Liu - In: Proceedings of the 20th International Conferences on Machine Learning , 2003
"... Feature selection, as a preprocessing step to machine learning, is effective in reducing di-mensionality, removing irrelevant data, in-creasing learning accuracy, and improving result comprehensibility. However, the re-cent increase of dimensionality of data poses a severe challenge to many existing ..."

existing feature selection methods with respect to efficiency and effectiveness. In this work, we intro-duce a novel concept, predominant correla-tion, and propose a fast filter method which can identify relevant features as well as re-dundancy among relevant features without pairwise correlation analysis

Animal Models Rats Susceptible to Virus-Induced Asthma Have a Persistent Virus-Induced Change in the Predominant Pulmonary Form of the

by Nf-kb Inhibitor Ikba, E. W. Uhl, T. J. Clarke, C. Lester, R. J. Hogan
"... Weanling Brown Norway (BN) rats are susceptible to persistent steroid-responsive pulmonary abnormalities following resolution of an acute respiratory virus infection. In contrast, Fischer 344 (F344) rats recover without complications. Previous studies determined that NF-kB activation and subunit com ..."

after inocula-tion (n 5 per group) did not reveal virus-induced differences in IkBb expression. In contrast, a lower molecular weight form of IkBa appeared in the BN rats at 14 days postinfection, and it was still present at 21 days after infection (n 5 per group). The change in IkBa expression

THE EXCRETION AND STORAGE OF AMMONIA BY THE AQUATIC LARVA OF SIALIS LUTARIA (NEUROPTERA)

by B. W. Staddon , 1954
"... Delaunay (1931), in a review of the invertebrates, showed that an excellent correla-tion existed between the nature of the major nitrogenous component of the excreta and the nature of the environment, aquatic or terrestrial, in which an animal lived. Ammonia was shown to predominate in the excreta o ..."

Short Communication In Vitro Investigation of Human UDP-Glucuronosyltransferase Isoforms Responsible for Tacrolimus Glucuronidation: Predominant Contribution of UGT1A4

by unknown authors , 2011
"... Tacrolimus (Tacro) is a potent immunosuppressant and a central agent in the prevention of posttransplantation rejection. Tacro is characterized by a narrow therapeutic index and wide interindi-vidual pharmacokinetic fluctuation. The contribution of human UDP-glucuronosyltransferase (UGT) in its meta ..."

-G formation. This conclusion is supported by the finding of inhibition with a specific substrate of UGT1A4 lamotrigine with Ki values similar for both human liver and UGT1A4 microsomes and the correlation with trifluoperazine-gluc-uronide formation by liver microsomes (rs 0.551; p 0.02).

"... Lymphoepithelial carcinoma (LEC) is most commonly seen in the nasopharynx. Very rarely it is found in the salivary gland, preferably in parotid gland followed by submandibular gland where it accounts for 0.4 % of all malignant salivary gland tumours. Most commonly it is seen in fifth decade with fem ..."

Very rarely it is found In Indians. So we present a case of LEC of parotid gland in a 23 year old male Indian patient

Evaluating the semantic categories hypothesis: the case of the mass/count distinction

by Peter Gordon - Cognition , 1985
"... It is often claimed that grammatical categories are initially acquired via their semantic properties. In the case of the count/mass distinction, semantic corre-lations should predispose the child to acquire the countlmass subcategories as a distinction between names for objects vs. substances. This ..."

An examination of the nature and correlates of ethnic harassment experiences in multiple contexts

"... The authors examined the nature and correlates of ethnic harassment experiences in 4 predominantly Hispanic samples of working men and women (N = 575) using a newly developed scale. Confirmatory factor analyses upported a 2-factor structure for the Ethnic Harassment Experiences scale (i.e., verbal e ..."

"... Trisomy 21 is the most frequent single chro-mosome aberration at birth [1]. Free trisomy, i.e. occurrence of 3 chromosomes 21, comprises about 95 % of all trisomies 21 [2, 3] and is due to (mostly meiotic) nondisjunction occurring predominantly in the female gamete [4, 5].

"... The paper presents seasonal changes in the concentrations of ammonia, nitrate and phosphate ions in podzolic soils under the Vaccinio uliginosi–Betuletum pubescentis and Empetro nigri-Pinetum plant communities. It results from the conducted investigations that the distribution and accumula-tion of m ..."
