The central limit theorem (CLT) is a powerful tool that allows us to make inferences about populations, even if we don’t know the exact distribution of the population. Just wave your wand (i.e., use the CLT) over a sample of data, and the distribution of the sample means will be... [Read More]

Relative estimation is a concept that simply means “comparing two things to each other.” If you’ve ever said something like, “Hey, this tree is twice as tall as that tree,” you already know how to do it. [Read More]

AdaBoost (Adaptive Boosting) is a popular boosting algorithm that combines multiple weak classifiers to create a strong classifier. The algorithm works by iteratively adjusting the weights of the training instances and focusing more on the misclassified instances in each iteration using a weighted sampled distribution. [Read More]
