KL Divergence

KL Divergence – What is it and mathematical details explained

At its core, KL (Kullback-Leibler) Divergence is a statistical measure that quantifies the dissimilarity between two probability distributions. Think of it like a mathematical ruler that tells us the “distance” or difference between two probability distributions. Remember, in data science, we’re often working with probabilities – the chances of events happening. So, if we have

Cook’s Distance for Detecting Influential Observations

Cook’s distance is a measure computed to measure the influence exerted by each observation on the trained model. It is measured by building a regression model and therefore is impacted only by the X variables included in the model. What is Cooks Distance? Cook’s distance measures the influence exerted by each data point (row /
