Choosing the Right Metric for Evaluating Machine Learning Models  –  Part 1

n the world of postmodernism, Relativism has been, in its various guises, both one of the most popular and most reviled philosophical doctrines. According to Relativism, there is no universal and objective truth; rather each point of view has its own truth.

Choosing the Right Metric for Evaluating Machine Learning Models — Part 2

In the first blog, we discussed some important metrics used in regression, their pros and cons, and use cases. This part will focus on commonly used metrics in classification, why should we prefer some over others with context.   Definitions Let’s

Cognitive Analytics Answers the Question: What’s Interesting in Your Data?

Bayes’ Rule Applied – William Koehrsen

Bayes’ Rule Applied Using Bayesian Inference on a real-world problem The fundamental idea of Bayesian inference is to become “less wrong” with more data. The process is straightforward: we have an initial belief, known as a prior, which we update as we
