Active Learning has become an important area of research owing to the increasing number of real-world problems which contain labelled and unlabelled examples at the same time. JCLAL is a Java Class Library for Active Learning which has an architecture that follows strong principles of object-oriented design. It is easy to use, and it allows the developers to adapt, modify and extend the framewo...

Generally speaking, the study of concepts in cognitive psychology is anthropocentric with respect to both content and theory. A broader comparative perspective on the various forms of concept learning not only provides a more inclusive view of conceptual behavior, but it also provides a more objective perspective from which to identify underlying processes. We suggest that several of the major ...

A number of tasks, such as large-scale text categorization and word prediction, can benefit from efficient learning and classification when the number of classes (categories), in addition to instances and features, is large, that is, in the thousands and beyond. We investigate learning of sparse category indices to address this challenge. An index is a weighted bipartite graph mapping features ...

In machine learning, one often encounters data sets where a general pattern is violated by a relatively small number of exceptions (for example, a rule that says that all birds can fly is violated by examples such as penguins). This complicates the concept learning process and may lead to the rejection of some simple and expressive rules that cover many cases. In this paper we present an approa...

The goal of robot learning from demonstration is to have a robot learn from watching a demonstration of the task to be performed. In our approach to learning from demonstration the robot learns a reward function from the demonstration and a task model from repeated attempts to perform the task. A policy is computed based on the learned reward function and task model. Lessons learned from an imp...

background. various educational approaches to learning have been proposed. it is, of course, of vital importance to study those that have resulted in effective educational achievements. purpose. to assess the student’s attitudes and performance in order to evaluate educational approaches and identify the variables leading to students gaining good marks. methods. the subjects of the study were m...

introduction traditional teacher-centered methods of teaching and learning are passive and affected by teacher's functions and horizons. today, active teaching methods include teaching  students to be able to observe the situation for exploring and thinking deeper about the issue or problem . so the aim of this study is to survey students' views about the advantages of quizzes  in stu...

The purpose of this study is to investigate the significant relationship between different young mothers’ social classes and children’s language learning. According to this research goal, this study is eager to answer the two major research questions: (a) Is there any significant difference between middle-class and working-class mothers’ speech? (b) Is there any significant relationship between...
