Bayesian Machine Learning Applications Examples

bayesian machine learning appplications examples

Have you ever wondered how machines can make decisions with uncertainty? What if there was anĀ  approach in machine learning that not only learned from data but also quantified and managed uncertainty in a principled way? Enter the realm of Bayesian machine learning. Bayesian machine learning is one of the most powerful modeling technique in predictive analytics. It marries the probabilistic reasoning with machine learning algorithms. Bayes’ theorem, which was first introduced by Reverend Thomas Bayes in 1763, provides a way to infer probabilities from observations. Bayesian machine learning has become increasingly popular because it can be used for real-world applications such as spam filtering (NLP), credit card fraud detection, …

Coefficient of Variation vs Standard Deviation

Coefficient of Variation Formula

Understanding the difference between coefficient of variation and standard deviation is essential for statisticians and data scientists. While both concepts measure variability in a dataset, they are calculated differently and can be used in different scenarios for better understanding. Here, we will explore the differences between these two measures to gain a better understanding of how to use them. What is Coefficient of Variation? Coefficient of Variation (CV) is a measure that is used to compare the amount of variation in a dataset relative to its mean value. It is calculated by taking the standard deviation divided by the mean, then multiplying by 100. CV can be interpreted as the …
