Smells like Teem Spirits

Great modelling is dependent on a great data set to train a model on. Contrary to all the advanced AI guff you see on LinkedIn, this requires hard graft, domain knowledge and initiative. There is no magic AI button to press when you leave the office and a model to use when you come back in the morning.


You may have read articles criticising AI for bias. A potential source of bias is errors in the training set. False positives and false negatives make for a bad model. At Fable Data we tag our European panel of anonymised consumer spend against traded companies, their main competitors and other merchants in the sector. Our clients need to know how Costa Coffee, now owned by Coca Cola [NYSE: KO], Caffè Nero Group [taken private in 2007] and the rest of the coffee market is trending. We go to great lengths to create accurate training datasets that cover every angle of consumer spend from ASOS to the Zoological Society of London and everything in between.


We must be able to correctly identify Premier Stores (Booker Group, Parent Tesco Group PLC LSE: TSCO) from billions of transaction string patterns. Here are a few examples of possible matches for Premier Stores. Which ones do you think are valid? The correct answers are at the bottom.
