Talk: Leveraging Old Tricks in A New World: Efficient Generation of Labeled Data for Deep Learning

07:00 - 07:45 PM (IST), December 05, 2020
5th IAPR International Conference on Computer Vision & Image Processing

In the emerging world of artificial intelligence algorithms and analytics, curated and labeled data is often considered the “new oil.” However, extracting this “oil” is often expensive and fraught with difficulties. Specifically, generation of labeled data can be labor intensive and tedious. Crowd sourcing can distribute the labor and mitigate the cost and tedium for some application scenarios. However, for other applications, such as medicine, the requirement of specialized knowledge and skills can make crowd sourcing unviable and generation of labeled data is therefore both expensive and limited, in volume and accuracy, by the availability of physicians’ time. The problem is even more acute for tasks requiring sample level labeling of large, high-resolution spatio-temporal datasets, for example, for pixel-level labeling of images for medical image segmentation. In this talk, through case studies, we highlight examples where creative use of conventional machine learning, computer vision, and image processing techniques allows us to efficiently generate labeled data for new applications of deep learning. The examples particularly highlight that these conventional tools continue to be effective and useful and will therefore co-existsymbiotically with modern deep learning methodologies.
