Advanced strategies for better customer insights The RFM (Recency, Frequency, Monetary) model, with its simplicity and ease of implementation, remains a great tool for customer relationship management, offering valuable insights into customer behaviour. Building on the groundwork from my previous article “How to Create an RFM Model in BigQuery”, in this article, we will explore…

Let’s begin with the idea of an ‘expert’ in this context. Experts are feed-forward neural networks. We then connect them to our main model via gates that will route the signal to specific experts. You can imagine our neural network thinks of these experts as simply more complex neurons within a layer. Figure 1 from…

tl;dr version: A team of students helped design and carry out an experiment to determine whether bowls of Lucky Charms are equally “lucky” over the course of a box of cereal. Turns out, not so much. We estimate a decrease of approximately 2.7 total charms per additional bowl on average. This corresponds to more than…

Estimating your chances of winning the lottery with sampling Statistical estimates can be fascinating, can’t they? By just sampling a few instances from a population, you can infer properties of that population such as the mean value or the variance. Likewise, under the right circumstances, it is possible to estimate the total size of the…

Let’s implement a regression example where the aim is to train a network to predict the value of a node given the value of all other nodes i.e. each node has a single feature (which is a scalar value). The aim of this example is to leverage the inherent relational information encoded in the graph…

Learn how to build neural networks for direct causal inference Photo by Geranimo on UnsplashBuilding machine learning models is fairly easy nowadays, but often, making good predictions is not enough. On top, we want to make causal statements about interventions. Knowing with high accuracy that a customer will leave our company is good, but knowing…

A Brief Tutorial Photo by Nabeel Hussain on UnsplashK-Means is a popular unsupervised algorithm for clustering tasks. Despite its popularity, it can be difficult to use in some contexts due to the requirement that the number of clusters (or k) be chosen before the algorithm has been implemented. Two quantitative methods to address this issue…
