The musings of a Data Scientist
In one of my previous posts on Bloom Filters, I stated the expressions for both the False Positive rate, ie $$p \approx \left( 1 – e^{\frac{-kn}{m}} \right)^{k}$$ and the optimal number of hash functions, ie $$k = \frac{m}{n} \ln 2$$ In this post I will detail the derivations of both expressions. Derivation of the False…
I’ve been lucky enough to have worked on many interesting and challenging projects throughout my career, especially in the space of detecting “bad” people. As one can imagine, much focus is placed on detecting persons of interest in the government sector. After all, you can’t ensure national security, for instance, without being able to detect…
I recently discussed how Confidential Computing allows us to analyse and use data without actually seeing it. A key component of Confidential Computing is Privacy-Preserving Record Linkage (PPRL), and one of the most widely used techniques within PPRL is the Bloom Filter (BF), which is the focus of this post. The aim is to give an overview of…
Blame it on misguided youth, blame it on greed, or blame it on just plain ignorance, but I have a confession to make: I spent the early part of my career working for a major investment bank. To be honest, it was a great opportunity as a young Data Scientist to learn how to apply…

Over the years I’ve helped a number of organisations, both large and small – public and private, build up their Data Science capabilities, and derive value from data using various analytical techniques. However, one key concern I’ve had a number of times is the confusion that can exist between means and ends ie solutions searching…
