What is the Bayesian Approach?
Bayesian statistics takes a different method, using observed data to update prior beliefs and generate posterior distributions. With this technique, probability indicates subjective levels of belief instead than long-term frequencies. Bayesian statistics provides a systematic approach to updating historical data and coherently characterizing uncertainty.
Based on Bayesian probability theory, which views probability as a gauge of one’s level of conviction or skepticism regarding an occurrence, the Bayesian approach is applied. In order to obtain posterior distributions, it takes into account past knowledge or assumptions about parameters, which are updated using observed data. By using data and past knowledge, Bayesian inference seeks to produce probabilistic estimates of parameters and predictions.
Bayesian linear regression, Gaussian processes, Bayesian neural networks, and Markov chain Monte Carlo (MCMC) methods are commonly used in Bayesian inference.
Frequentist vs Bayesian Approaches in Machine Learning
Frequentist and Bayesian approaches are two fundamental methodologies in machine learning and statistics, each with distinct principles and interpretations. Here, we will see how these two approaches differ.
