Explanation video of how to do Open-QA using ORQA formulation

Hi, in this video, I explain ORQA which uses a retriever to find the right context from the entire Wikipedia and then uses an extractive QA model to give a final answer. We discuss the task setup, architecture, and loss function.

The video is part of 8 video series on Open domain question answering, how it is different from normal QA, the difference in loss formulations, and key papers on different Open-QA architectures.

I will really appreciate any feedback. Thanks. …
