Application significance:

Tu Zipei, a big data expert and vice president of Alibaba Group, said that the excellent data model obtained in the contest can not only be used for the academic research results of the contestants, but also have the opportunity to go out of the laboratory and directly apply it to real business scenarios such as Taobao and Alipay, affecting hundreds of millions of users in China and even around the world. In the previous Tmall Recommendation Algorithm Competition, the personalized recommendation algorithm developed by six post-90s college students surpassed the original Tmall algorithm with a score of 1 1 and won a prize of 1 10,000 yuan.

Tu Zipei said that the era of data economy is coming. In 20 15 years, China's data volume accounts for 14% of the world, and this proportion will rise to 2 1% by 2020. But our data utilization rate is less than 0.4%, and more data is still sleeping in every corner. China needs effective data processing methods and big data talents. Alibaba Cloud Tianchi Competition will become a data creation platform, attracting more governments and companies to open data resources, innovating data business models, and detonating the power of a new generation and the energy of data economy.
