Higher Criticism Thresholding: Optimal Feature Selection when Useful Features
Motivated by many ambitious modern applications – genomics and proteomics are examples, we consider a two-class linear classification in high-dimensional, low-sample size setting (a.k.a. p n). We consider the case where among a large number of features (dimensions), only a small fraction of them is useful. The useful features are unknown to us, and each of them contributes weakly to the classif...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Mexican Neuroimmunoendocrinology: What is Done and has to be Done
In this special issue of The Open Neuroendocrinology Journal, the reader will find reviewed some of the hottest topics in the field of Neuroendocrine-immune interactions, with emphasis on the work performed by Mexican Scientists in the field, celebrating the launching of The Mexican Society of Neuroimmunoendocrinology. Cabrera-Muñoz et al., describe the role of progesterone (P4) in the infectio...
متن کاملDeclarativeness: the work done by something else
Being declarative means that we do computer programming on higher levels of abstraction. This vague definition identifies declarativeness with the act of ignoring details, but it is a special case of abstraction. The unspecified part is some computational work. Automating computations and offloading mental processing are essentially the same concept, which is fundamental for both computational ...
متن کاملHigher criticism thresholding: Optimal feature selection when useful features are rare and weak.
In important application fields today-genomics and proteomics are examples-selecting a small subset of useful features is crucial for success of Linear Classification Analysis. We study feature selection by thresholding of feature Z-scores and introduce a principle of threshold selection, based on the notion of higher criticism (HC). For i = 1, 2, ..., p, let pi(i) denote the two-sided P-value ...
