Researchers at MSR published the first MS-Celeb-1M dataset, comprising images of real-life celebrities, in June 2016 to encourage the development of advanced facial recognition technologies.

BEIJING, July 26, 2017 /PRNewswire/ -- Beijing OrionStar Technology Co., Ltd. ("OrionStar"), a China-based artificial intelligence company with which Cheetah Mobile Inc. (NYSE: CMCM) ("Cheetah Mobile") has entered into an investment agreement, recently ranked number one in the "MS-Celeb-1M" challenge, a competition to recognize and identify images of one million celebrities in a pre-set database. The challenge was organized by Microsoft Research (MSR) for a workshop at ICCV 2017, the world's premier international computer vision event.

Researchers at MSR published the first MS-Celeb-1M dataset, comprising images of real-life celebrities, in June 2016 to encourage the development of advanced facial recognition technologies. At the same time, they launched the first MS-Celeb-1M facial recognition challenge. Participants in the challenge are tasked with using a dataset provided by MSR as training data to develop an image recognition system capable of recognizing one million celebrities.

To evaluate the results, a subset of celebrities was selected from MSR's one-million celebrity list. Images of those celebrities were then carefully labelled and organized into two sets: a "random" set, in which one image is randomly selected for each celebrity from the labelled images; and a "hard" set, which includes the labelled image from each celebrity that is the most different from any other image in the training dataset.

Among this year's participants, OrionStar ranked first in the "Without External Data" category (only using the dataset provided) of the challenge with a 0.750 coverage probability for the random set and 0.606 for the hard set. During last year's challenge, MS-Celeb-1M @ ACM MM2016, the best performance without external data was 0.734 with the random set and 0.534 with the hard set (among 13 teams). The "Without External Data" challenge is significantly more difficult than the "With External Data" challenge, which allows competitors to access data from outside sources.

The facial recognition technology utilized by the OrionStar team in this challenge will have real-world applications for Cheetah Mobile products, including facial recognition software, robotics and mobile apps.

OrionStar's facial recognition technology is already being used in Cheetah Mobile's Live.me social live broadcasting app. Every day, Live.me produces more than 200,000 hours of live content. To ensure a wholesome experience, Live.me employs a 24-hour real-time monitoring system based on facial recognition technology developed by OrionStar. The technology has other uses as well, including the ability to recognize brand logos and support ad testing, generate user tags based on a variety of characteristics, and provide personalized content recommendations. It also supports all types of dynamic facial mapping.
