background: workplace stress is known to be related with many behavioral and disease outcomes. however, little is known about its prospective relationship with measures of cognitive decline. objective: to investigate the association of job strain, psychological demands and job control on cognitive decline. methods: participants from framingham offspring cohort (n=1429), were assessed on job str...

For many supervised leaming tasks, the cost of acquiring training data is dominated by the cost of class labeling. In this work, we explore active learning for class probability estimation (CPE). Active learning acquires data incrementally, using the model learned so far to help identify especially useful additional data for labeling. We prcscnt a new method for activc lcarning, BootstrapLV, wh...

This study examines the evidence for the effectiveness of active learning. It defines the common forms of active learning most relevant for engineering faculty and critically examines the core element of each method. It is found that there is broad but uneven support for the core elements of active, collaborative, cooperative and problem-based learning.

Active Learning (AL) methods seek to improve classifier performance when labels are expensive or scarce. We consider two central questions: Where does AL work? How much does it help? To address these questions, a comprehensive experimental simulation study of Active Learning is presented. We consider a variety of tasks, classifiers and other AL factors, to present a broad exploration of AL perf...
