Feature subset selection has become more and more a common topic of research. This popularity is partly due to the growth in the number of features and application domains. It is of the greatest importance to take the most of every evaluation of the inducer, which is normally the more costly part. In this paper, a technique is proposed that takes into account the inducer evaluation both in the ...

Natural killer (NK) cells are a distinct lymphocyte subset that, like cytotoxic T cells, recognize and destroy abnormal self-cells. Unlike T cells, however, NK cells lack a uniquely rearranged antigen receptor gene or a single defining immunophenotypic attribute. Furthermore, there is considerable functional and phenotypic overlap between NK cells and cytotoxic T cells, and the latter are induc...

Background: Killer cell immunoglobulin-like receptors (KIR) are expressed on NK cells and a subset of T cells. The variable KIR receptors along with their ligands, HLA class I, influence risk for autoimmune and malignant diseases. Objective: To investigate the KIR gene profiles in relation to susceptibility to Graves’ disease in patients with ophthalmopathy. Methods: KIR genes profiles were ana...

In this paper, a novel filter-based approach is proposed using the PageRank algorithm to select the optimal subset of features as well as to compute their weights for web page classification. To evaluate the proposed approach multiple experiments are performed using accuracy score as the main criterion on four different datasets, namely WebKB, Reuters-R8, Reuters-R52, and 20NewsGroups. By analy...

Let A be a zero-sum free subset of Zn with |A| = k. We compute for k ≤ 7 the least possible size of the set of all subset-sums of A.
