Overview of Probabilistic Models

In the context of supervised learning, it’s more advantageous to predict the distribution of the target variable It is the variable that we want to predict using the rest of the dataset. rather than a specific fixed value. In fact, numerous classification and regression models implicitly calculate the underlying distribution and generate a fixed target by sampling from this distribution.

Note: A probability distribution is a mathematical function that describes the likelihood of different outcomes occurring in a random experiment. It provides a way to model and quantify the uncertainty associated with various events or values.

The most common approach involves sampling the value with the highest probability, although alternative sampling methods also exist. However, certain models don’t lend themselves easily to estimating a probability distributionIt refers to the process of determining the shape and characteristics of a probability distribution based on available data. for the target variable. In situations where obtaining samples of the target variable proves difficult, we turn to conventional machine learning models as an alternative solution.
