Metrics in machine learning As some of you might know, metrics in machine learning is one of my favourite topics. I have already spoken about RMSE and MAE, Cohen’s Kappa, the concordance correlation coefficient and other metrics. On this post, I’d like to talk about another very important metric: The Read more…
Note: This is an excerpt from my new book-in-progress called “Uncertainty”. The most popular definition of probability, and maybe the most intuitive, is the frequentist one. According to frequentists, an event’s probability is defined as the limit of this event’s frequency in a large number of trials. What does this Read more…
AI and creativity As many of you know, I am a big fan of the space of AI and creativity. This is a space I have worked on and blogged about in the past, and I am still active in. I am also the admin of the AI and Creativity Read more…
Data science is ever evolving, and with so many things going on it can be difficult to keep track of all the new libraries and algorithms. This is when it can be really useful to have a reference guide to help you out. Continuing from our series about cheatsheets, in Read more…
How much do you really know about the journey that a typical customer of your business takes to get to the stage of making a purchase?
