    Minimizing Supervision in Multi-label Categorization

    Multiple categories of objects are present in most images. Treating this as a multi-class classification is not justified. We treat this as a multi-label classification problem. In this paper, we further aim to minimize the supervision required for providing supervision in multi-label classification. Specifically, we investigate an effective class of approaches that associate a weak localization with each category either in terms of the bounding box or segmentation mask. Doing so improves the accuracy of multi-label categorization. The approach we adopt is one of active learning, i.e., incrementally selecting a set of samples that need supervision based on the current model, obtaining supervision for these samples, retraining the model with the additional set of supervised samples and proceeding again to select the next set of samples. A crucial concern is the choice of the set of samples. In doing so, we provide a novel insight, and no specific measure succeeds in obtaining a consistently improved selection criterion. We, therefore, provide a selection criterion that consistently improves the overall baseline criterion by choosing the top k set of samples for a varied set of criteria. Using this criterion, we are able to show that we can retain more than 98% of the fully supervised performance with just 20% of samples (and more than 96% using 10%) of the dataset on PASCAL VOC 2007 and 2012. Also, our proposed approach consistently outperforms all other baseline metrics for all benchmark datasets and model combinations.Comment: Accepted in CVPR-W 202

    In this presentation the author has mainly considered metallics inputes for Steel/Iron melting through Induction melting route. Induction melting for ferrous products at viable cost was unheard of two decades ago. So also the use of Sponge iron or Pig Iron as inputs for making steel was unimaginable through Induction melting furnaces route. Revolutionary changes are taking place all over the world. The factors governing evolution of process depends upon local, regional, geographical and economic considerations. A process suitable in European conditions may have to undergo changes when used in other countries or region
