The paper “The Importance of Convexity in Learning with Squared Loss” gave a lower bound on the sample complexity of learning with quadratic loss using a nonconvex function class. The proof contains an error. We show that the lower bound is true under a stronger condition that holds for many cases of interest.
Generalized chain ratio regression and chain regression estimators for the population mean using two auxiliary characters have been proposed in the presence of non-response. The expressions for the mean square error (MSE) of these estimators have been obtained for fixed sample sizes ( n′ and n ) and also for fixed cost 0 C C ≤ .The optimum values of the first phase sample size n′ and the sub sa...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
This article develops statistical methods for testing the equality of two distributions based on independent samples generated in some separable metric space. Such are broadly applicable identifying similarity or distinction complicated data sets (e.g., high-dimensional functional data) collected a wide range research industry areas, including biology, bioinformatics, medicine, material science...

یادگیری مشارکتی دارای مزایای فراوانی می باشد. اهداف اصلی این تحقیق عبارتند از: 1- تاثیر یادگیری مشارکتی بر دستاورد واژگان تخصصی دانشجویان، 2- تاثیر یادگیری مشارکتی بر نگرش دانشجویان و 3- تاثیر مدرسین متفاوت بر دستاورد دانشجویان در کلاسهای سنتی و مشارکتی. از بین 78 دانشجوی سال دوم داروسازی 60 نفر بطور تصادفی انتخاب و به دو کلاس مساوی تقسیم شدند. جهت کنترل تاثیر شخصیت مدرسین بر دستاورد دانشجویان ...
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...
