At dunnhumby, our team of 500 data scientists are the experts in Customer Data Science. They use the latest techniques and modelling to make sense of customer behaviour, and ultimately help retailers and brands to put the customer first.
But we realise that not everyone is quite as familiar with the complexities of AI and Machine Learning. So, our data scientists have put together a guide to some of the terms you’ll often hear when working with dunnhumby.
