报告题目：From Big Multimedia Data to Real-World Visual Search (& an introduction to the upcoming Alibaba Image Search Challenge)
报告人：Senior Director: Xian-Sheng Hua (Alibaba Group)
Visual search has been studied for decades since 1990s and it was called “content-based image retrieval” in the beginning. It almost died in the early 21st century and then becomes very hot in recent years mainly due to the rapid development of distributed computing, high-dimensional indexing, deep learning and big data analytical techniques. Many visual search research prototypes and preliminary products are available to the public. However, is real-world visual search really coming? Have we solved all the big technical and non-technical challenges? Are semantic gaps and intention gaps still there, and do they really matter? How big data analyses and deep learning techniques can help here? Are people really using it and why do they want to use it? Which direction that visual search is going towards? What are still missing? In this talk, we will discuss all these questions based on a real-world visual search engine that has a considerable number of users. And we will also introduce the upcoming “Alibaba Large-Scale Image Search Challenge”, in which we will award more than 400K RMB in total to winning teams.
