Research on “Internet Advertising and Optimal Auction Design” who discussed Generalized English Auctions  and Internet advertising, generalized second price options.

It was a great talk where Jitendra discussed the evolution of vision, image search, shortcomings of tagging and textual taxonomies and pushed for "category recognition" for objects in images.
Later there were the following excellent sessions.
