[quick news] March 15, 2019 can't be avoided! Universities use AI for roll call, and students will automatically receive calls when they are absent from class

Can't hide! Universities use AI to call, students will automatically receive a call after the classroom installation of monitoring probes, fingerprint punch, universities call means to upgrade again 13, a section called "Ai dominated fear! Colleges and universities develop AI system to urge truant students to attend classes According to the video, recently, Hangzhou University of Electronic Science and Technology launched an AI system, which can help teachers call names and urge students who are absent from class to come to class The Counselor's intelligent voice assistant "little AI" will remind the students that they have been absent from class, ask the reasons why they did not arrive at the class, and introduce the corresponding school punishment regulations, including staying in school for observation, disqualification of examination, etc What's more, students' absenteeism information will be synchronized to counselors and recorded For this black technology, the school students lamented, "there is no way to hide." However, the effect is also visible The students feel that the class attendance rate is indeed getting higher now Https://baijiahao.baidu.com/s?

Researcher Wei Dacheng said This technology will provide a new way to solve the problem of chip cooling https://
