开云app官网:演讲简介

Modern metro transportation systems are starting to witness CV-enabled automatic fee collection, where customer photos are captured at subway turnstiles and matched against a large pre-registered user database. Previous studies feature both local database per station and a centralized database at the cloud. In the latter case, they rely on classic network transmission of AI data, and work on turnstile algorithm design and cloud-side face matching separately. Such remote face matching are mission- critical and face multi-facet challenges: efficient face detection and embedding, effective network transmission, and fast vector matching against a large database in the latent space. The final goal is an all-inclusive end-to-end RTT upper-bounded by ~300ms. This work presents a holistic remote CV system design, where front-end embedding, UEP-enabled AI data transmission and progressive cloud-side matching are judiciously designed to work in concert, to simultaneously optimize accuracy and delay of the distributed AI application. In particular, our design of numerical FEC may be of independent interest in the era of AI. Both AI models and input are represented with high volume of numerical data, calling for new, optimized transmission algorithms, which we call “AI networking”.
