Covariance-guided One-Class Support Vector Machine (COSVM) is a very competitive kernel classifier, as it emphasizes the low variance projectional directions of the training data, which results in high accuracy. However, COSVM training involves solving a constrained convex optimization problem, which requires large memory and enormous amount of training time, especially for large scale datasets...
In this paper, an augmented Lagrangian proximal alternating (ALPA) method is proposed for two class of large-scale sparse discrete constrained optimization problems in which a sequence of augmented Lagrangian subproblems are solved by utilizing proximal alternating linearized minimization framework and sparse projection techniques. Under the MangasarianFromovitz and the basic constraint qualifi...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
در مطالعه فون کنه‌های زیان‌آور درختان پهن برگ و درختچه‌های زینتی که در سال‌های ۱۳۸۷ و ۱۳۸۸ در فضای سبز مشهد انجام گرفت، نمونه‌هایی از چهار گونه کنه از خانواده تترانیکیده، متعلق به 3 جنس به نام‌های: Oligonychus mangiferus (Rahman and Sapra, 1940)، Oligonychus yothersi (Mc Gregor 1914)، Schizotetranychus hindustanicus (Hirst, 1924)و Eutetranychus africanus (Tuker, 1926) شناسایی گردید که برای فون ...
در مطالعه فون کنه های زیان آور درختان پهن برگ و درختچه های زینتی که در سال های ۱۳۸۷ و ۱۳۸۸ در فضای سبز مشهد انجام گرفت، نمونه هایی از چهار گونه کنه از خانواده تترانیکیده، متعلق به 3 جنس به نام های: oligonychus mangiferus (rahman and sapra, 1940)، oligonychus yothersi (mc gregor 1914)، schizotetranychus hindustanicus (hirst, 1924)و eutetranychus africanus (tuker, 1926) شناسایی گردید که برای فون ...
as polysemy is encountered frequently in english as foreign language. fl learners’ ability to disambiguate polysemous verbs becomes critical to their comprehension in the target language. this thesis, accordingly, investigated how iranian efl learners achieved comprehension of english polysemous verbs by using three different types of cues: (1) elaborated context, (2) semantic frames, and (...
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
Abstract In this paper, for a nonsmooth semi-infinite multiobjective programming with locally Lipschitz data, some weak and strong Karush-KuhnTucker type optimality conditions are derived. The necessary conditions are proposed under a constraint qualification, and the sufficient conditions are explored under assumption of generalized invexity. All results are expressed in terms of Clarke subdif...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
