MetaWeighting: Learning to Weight Tasks in Multi-Task Learning

no code implementations Findings (ACL) 2022 YUREN MAO, Zekai Wang, Weiwei Liu, Xuemin Lin, Pengtao Xie

Task weighting, which assigns weights on the including tasks during training, significantly matters the performance of Multi-task Learning (MTL); thus, recently, there has been an explosive interest in it.
