Abstract Multi-task learning, in which several tasks are jointly learned by a single model, allows NLP models to share information from multiple annotations and may facilitate better predictions when the inter-related. This technique, however, requires annotating same text with annotation schemes, be costly laborious. Active learning (AL) has been demonstrated optimize processes iteratively sel...

purpose: this study aimed to examine the differences in the co-activation of the rectus femoris (rf) and biceps femoris (bf) using the co-contraction index (ci) in aquatic and land environments during a drop-landing task in active and non-active females. methods: in this casual-comparison study, 10 active and 10 non-active females volunteered to participate. the ci was calculated from recorded ...

Design of selective cyclooxygenase-2 (COX-2) inhibitors is still a challenging task because of active site similarities between COX isoenzymes. To help with this issue, we tried to generate a 3D-QSAR (3 dimensional quantitative structure activity relationship) model that might reflect the essential features of COX-2 active sites. Compounds in a series of resveratrol derivatives inhibitors with ...

The Group-Lasso is a well-known tool for joint regularization in machine learning methods. While the `1,2 and the `1,∞ version have been studied in detail and efficient algorithms exist, there are still open questions regarding other `1,p variants. We characterize conditions for solutions of the `1,p GroupLasso for all p-norms with 1 ≤ p ≤ ∞, and we present a unified active set algorithm. For a...

There are several conflicting evidences showing the effect of morphine on learning and memory processes. In the present study the effect of chronic morphine administration on passive avoidance, active avoidance and spatial learning and memory of morphine dependent male rats using Passive Avoidance shuttle box and Morris Water Maze tasks were investigated, respectively. Male rats received morphi...

Introduction: Learning and memory deficits in some diseases are new subjects of research. Bupropion, as dopamine and noradrenaline reuptake inhibitor and an antidepressant agent, has been previously shown to affect learning and memory processes. This study was designed to test the effect of intra-hippocompal bupropion injection on active avoidance learning task in rats. Methods: Adult male ...
