is typically addressed in a fully\055supervised setup with manual annotation of training videos required at every frame\056 Since such annotation is extremely tedious and prohibits scalability\054 there is a clear need to minimize the amount of manual supervision\056 In this work we propose a unifying framework that can handle and combine varying types of less demanding weak supervision\056 Our model is based on discriminative clustering and integrates different types of supervision as constraints on the optimization\056 We investigate applications of such a model to training setups with alternative supervisory signals ranging from video\055level class labels over temporal points or sparse action bounding boxes to the full per\055frame annotation of action bounding boxes\056 Experiments on the challenging UCF101\05524 and DALY datasets demonstrate competitive performance of our method at a fraction of supervision used by previous methods\056 The flexibility of our model enables joint learning from data with different levels of annotation\056 Experimental results demonstrate a significant gain by adding a few fully supervised examples to otherwise weakly labeled videos\056) /Producer (PyPDF2) /Title (A flexible model for training action localization with varying levels of supervision) /Date (2018) /ModDate (D\07220190218211057\05508\04700\047) /Published
