Deep Learning Based Recommendation Engines using Keras
One thing that I have been thinking a lot about since I wrote my chapter on matrix factorization methods, and since I am currently writing a chapter on graph theory is on the idea of a recommendation engine. (If you […]
Using Networkx in Python to Find the Best Team Via a Directed Graph
Yep, we’re going there. Which football team is the best? Well, ask any fan and they are going to tell you that it is their personal favorite. But we are data scientists. Surely, we can do better! And of course, […]
