  • ML Concepts: Words Embedding

    Intro I keep going with the motivation of my upcoming small/simple session about ML and Cybersecurity. Last time I discussed an unsupervised clustering algorithm. We used multi-dimensional points (coordinates) in space. But what if our data is text? That’s common in “general”, but also in Cybersecurity. So the question becomes: Can we treat “text” as…

  • ML Concepts: Unsupervised Learning – Clustering – DBScan

    Intro So as I keep working on an upcoming presentation I shall give in a few weeks, I thought I’d prepare something a bit more “live” than just a PPT with Memes (although who doesn’t like a few Memes in a PPT?). My current idea is to talk about some “Machine Learning Key Concepts”, and…

  • Random Exercises: Interpolation with Lagrange Polynomials

    Intro As I want to make sure I keep posting here, I keep looking for things to write about in my own personal “library” (book shelves). One topic I want to make sure I don’t forget about is “Numerical Methods”. (Another one is graph theory, another one is anomaly detection… There are a few topics…
