Andrew Banh
Andrew graduated from the University of Sydney with a double degree in Commerce and Science. His love of data drew him to The Data School where he can apply his diverse skillset to make business decisions which are driven by data. Joining DSAU2 seemed like the logical step for Andrew. While he isn’t developing attractive Tableau viz’s, he juggles bouldering, cooking and taking weekend trips down to Perisher when it gets colder.
Dashboard Week: Keeping our Truckies safe
Last dashboard of dashboard week! Today we are looking at Motor Vehicle Census data from the Australian Bureau of Statistics. When I think of ABS data, vehicle census data has never crossed my mind but I am glad that we are exposed to this today. Firstly, with the...

Dashboard Week: Such an ‘EVENTFUL’ day
2nd last day of dashboard week! Our task was to use Eventful’s API to webscrape events from their website. The brief was quite open ended. Just use the API and make something. So, something I made! The difficulty begins with the data we actually extracted from the...

Barking mad for Decision Trees
A Decision Tree is a powerful machine learning model which has the added bonus of being easy to understand, as it can be used to visually understand the model. Luckily, last week we had our 2nd taste of Predictive Analytics where we looked at Decision Trees. A...

Their API allows you to access detailed information on each of the restaurants which you can massage and, if you’re a foodie like myself, use that information to find the next restaurant to indulge at.
