Data Science and Machine Learning (Theory and Projects) A to Z - Optional Estimation: MAP

The video tutorial introduces the concept of the Maximum a Posteriori (MAP) estimator, highlighting its differences from the Maximum Likelihood Estimator (MLE). It explains that MAP treats parameters as random variables with their own distributions, using the exponential distribution as an example. The tutorial discusses the role of MAP in regularization techniques within machine learning, emphasizing its importance in model generalization. The video concludes with a preview of upcoming topics, including MLE and MAP applications in logistic and Ridge regression.
