Monte Carlo Approximation Methods: Which one should you choose and when?

  Since deterministic inference is often intractable with probabilistic models as we saw just now, we now turn to approximation methods based on numerical sampling, which are known as Monte Carlo techniques. The key question we will look at with these methods is computing the expec...

Stirling’s Approximation for Factorials — Proof and Applications

Factorial is one of the ubiquitous concepts in mathematics. It is also an important mathematical concept used in data science. For modeling probability distributions in the Poisson process, factorial is used. The probability mass function of the Poisson distribution has factorial expression in the d...
