With the World Cup in Russia wrapping up on the same evening as our ninth un-hackathon, football was on our minds, and, with tongue in cheek, Data Science Hong Kong co-organiser Xavier put the question to our cohort of predictive modellers to find the winner, hours before the result was known.

We were asked to build a predictive model for the world cup result, but our vote worked well enough. 

Getting down to more serious stuff, Houston Ho presented his company’s work on using machine learning to predict whether an employee is due to leave their position. His tool aims to give human resources teams a score for each employee based on a variety of characteristics. His model is achieving 80% accuracy and he says he can achieve more.

See his presentation below.

DSHK co-organiser Guy Freeman also presented about his new development offering a central repository for scraped data, using an open source philosophy. He showed the system’s potential by using a dataset of property transactions in Hong Kong spanning 20 years.

Group projects

Michael attracted the most interest among the group in his restaurant prediction model project. Using data from two restaurant booking systems, he aimed to predict how busy a restaurant would get using a machine learning model.

See the results from the group’s work in the slides below.

Forecasting Visitors of Restaurants

Visiting from Tokyo, Suzana Ilic brought exciting skills to the unhackathon, and decided to set her sights on unpicking hype in the crypto space. She was a bit camera shy so no video but you can see her slides below.

Quantifying Hype

Morris Wong aimed to build an auto-tagging system for publishing, along the lines of taggernews. This tech could have wide-scale application when it’s up and running. See his presentation below.

That’s it for this month’s event. We will be announcing our next event shortly.
