In the last few lectures we have seen how to obtain high confidence bounds on the generalization error of functions learned from function classes of limited capacity, measured in terms of the growth function and VC-dimension for binary-valued function classes in the case of binary classification, and in terms of the covering numbers, pseudo-dimension, and fat-shattering dimension for real-value...

the study examines production efficiency of farmers under national fadama-ii project in oyo state nigeria. primary data were collected from two hundred and sixty-four farmers using multistage sampling technique. the analytical framework used for the study include: descriptive, infrastructure index, gross margin and stochastic frontier production function. average infrastructural index in the ar...

abstract the main aim of the paper is to determine the marketing efficiency of poultry industry in karaj. in this research the marketing margin and the marketing efficiency of poultry market in different level of the market in karaj was calculated. the results showed that slaughter houses gain the main part of marketing margin and marking profit. the share of slaughter house was more that 50 pe...

This article is about the unexpected linguistic behavior that young children sometimes display by producing structures that are only marginally present in the adult language in a constrained way, and that adults do not adopt in the same experimental conditions. It is argued here that children's capacity to overextend the use of given syntactic structures thereby resulting in a grammatical creat...

Production data suggest that meanings of common nouns continue to change well past the early years of language acquisition (Andersen, 1975; Ameel, Malt, & Storms, 2008). Here we used two comprehension tasks to further evaluate the nature of later lexical learning. In a name applicability task, sevento 13-year old Dutch-speaking children judged whether each of three names applied to common house...

In this essay, I explore how cognitive science could illuminate the concept of beauty. Two results from the extensive literature on aesthetics guide my discussion. As the term "beauty" is overextended in general usage, I choose as my starting point the notion of "perfect form." Aesthetic theorists are in reasonable agreement about the criteria for perfect form. What do these criteria imply for ...

Anaphase central spindle formation is controlled by the microtubule-stabilizing factor PRC1 and the kinesin KIF4A. We show that an MKlp2-dependent pool of Aurora B at the central spindle, rather than global Aurora B activity, regulates KIF4A accumulation at the central spindle. KIF4A phosphorylation by Aurora B stimulates the maximal microtubule-dependent ATPase activity of KIF4A and promotes i...

healthy 58-year-old woman had undergone arthrosopy of both temporomandibular joints because of ilateral mandibular clicks and recurrent episodes of aw block that did not respond to nonsurgical treatent. The preoperative examination showed general estriction of mandibular motility (maximal oral aperure 26 mm, right and left lateral deviation 11 and 8 m, respectively, protrusion 10 mm, and dental...
