(1999). "Regressions" ("u"-shaped learning) in the acquisition of prosodic structure. This paper addresses learning of constraint rankings by children. We argue that constraint demotion cannot account for all developmental patterns observed in child phonology. Learning algorithms that allow for constraint promotion fare better, but some still cannot account for all developmental changes. Child ...

U-shaped learning is a learning behaviour in which the learner first learns a given target behaviour, then unlearns it and finally relearns it. Such a behaviour, observed by psychologists, for example, in the learning of past-tenses of English verbs, has been widely discussed among psychologists and cognitive scientists as a fundamental example of the non-monotonicity of learning. Previous theo...

U-shaped learning behaviour in cognitive development involves learning, unlearning and relearning. It occurs, for example, in learning irregular verbs. The prior cognitive science literature is occupied with how humans do it, for example, general rules versus tables of exceptions. This paper is mostly concerned with whether U-shaped learning behaviour may be necessary in the abstract mathematic...

U-shaped learning deals with a learner first having the correct hypothesis, then changing it to an incorrect hypothesis and then relearning the correct hypothesis. This phenomenon has been observed by psychologists in various studies of children development. In this survey talk, we will discuss some recent results regarding U-shaped learning and related criteria.

The main aim of the project is to propose a QR-based U-Learning Material Production System (QR-ULMPS) to develop context-aware u-learning environment during outdoor learning activities. As portability and mobility are necessary factors for an authentic outdoor learning experience, our QR-ULMPS needed to incorporate versatile mobile devices. With the help of word net tool and natural language pr...

In learning, a semantic or behavioral U-shape occurs when a learner rst learns, then unlearns, and, nally, relearns, some target concept (on the way to success). Within the framework of Inductive Inference, previous results have shown, for example, that such Ushapes are unnecessary for explanatory learning, but are necessary for behaviorally correct and non-trivial vacillatory learning. Herein ...

U-Pace, an instructional intervention, has potential for widespread implementation because student behavior recorded in any learning management system is used by U-Pace instructors to tailor coaching of student learning based on students’ strengths and motivations. U-Pace utilizes an online learning environment to integrate content mastery with Amplified Assistance (instructor-initiated, indivi...

Alzheimer's illness (AD) is observed to be a neurodegenerative ailment that moderately degrades memory and thinking abilities. Despite the fact indications are kind-hearted at first, they become more serious over long haul. infection predominant kind of dementia. Dementia an all-inclusive term for loss other brain related activities leads interference in day life. Alzheimer’s one disease fundam...
