Common Probability Distributions – Sean Owen – Medium

Data scientists have hundreds of probability distributions from which to choose. Data science, whatever it may be, remains a big deal. "A data scientist is better at statistics than any software engineer," you may overhear a pundit say, at your local tech get-togethers and hackathons. The applied mathematicians have their revenge, because statistics hasn't been this talked-about since the roaring 20s. They have their own legitimizing Venn diagram of which people don't make fun. Suddenly it's you, the engineer, left out of the chat about confidence intervals instead of tutting at the analysts who have never heard of the Apache Bikeshed project for distributed comment formatting.

What is a Probability Distribution ? Determine its Type for Your Data

Probability Distribution is an important topic that each data scientist should know for the analysis of the data. It defines all the related possibility outcomes of a variable. In this, the article you will understand all the Probability Distribution types that help you to determine the distribution for the dataset. There are two types of distribution. In the discrete Distribution, the sum of the probabilities of all the individuals is equal to one.

Discrete Probability Distributions for Machine Learning

The probability for a discrete random variable can be summarized with a discrete probability distribution. Discrete probability distributions are used in machine learning, most notably in the modeling of binary and multi-class classification problems, but also in evaluating the performance for binary classification models, such as the calculation of confidence intervals, and in the modeling of the distribution of words in text for natural language processing. Knowledge of discrete probability distributions is also required in the choice of activation functions in the output layer of deep learning neural networks for classification tasks and selecting an appropriate loss function. Discrete probability distributions play an important role in applied machine learning and there are a few distributions that a practitioner must know about. In this tutorial, you will discover discrete probability distributions used in machine learning.
