e engaged in research regarding the credibility of online news during IM2C 2020 held
Win November 2019 and aimed to deliver a competent mathematical model to assess the
authenticity of online news through our project. For instance, we dived deeply into analyzing
various news sources on the Internet and developed a wide array of indicators like the reputation
of the websites and the objectivity of the content. During the whole course of the project, we
established a greater and broader understanding of the situation of the domination of false news on
the Internet and took a shot at inventing a mathematical model, which we had never done in the
past.

NGAI Ming Yu (6A, 2020-2021)
Hong Kong Mathematics Olympiad ur team aimed to design a smart water data analysis

Omodel by observing given data patterns in the differences
between water input and output flow using flow meters and
detecting the abnormalities. We adopted several approaches
to analyzing the data patterns by observing the slope in linear
regression and using graph standardization. I was amazed by
the utility of mathematical application, especially the relevant
concepts of optimization and linear regression. It is believed
that the serious problem of water leakage faced by the public
can be tackled in the future by warning the Water Supplies
Department and the public of the abnormal water flow and
thus preventing potential leaks from turning into a serious
water leakage problem.
