Y-combinator: The Y-combinator is a function that takes a function and returns another function. The returned function takes two arguments: a number n and a list xs of length n. It returns the first element of xs if n is 0 or 1, and the product of the first two elements of xs otherwise.
Definition of R-squared R-squared: R-squared is a statistic that measures how close the data points in a set are to a regression line (how well a model fits the data). It is a number between 0 and 1, with 1 indicating a perfect correlation and 0 indicating no correlation at all. It is calculated by…
Definition of Normalized Normalized: Normalized is a statistic term referring to the process of adjusting a value to have a unit of measurement. For example, the value of weight can be normalized by dividing it by the unit of weight, such as kilograms.
Definition of Laplace Approximation Laplace Approximation: The Laplace approximation is a method used in mathematics to approximate the value of a function. It is named after the mathematician Pierre-Simon Laplace, who first proposed it in 1774. The approximation is based on the assumption that the function is smooth, which means that it can be approximated…
Definition of Predictive Analytics Predictive analytics is the practice of using data mining and machine learning techniques to make predictions about future events. Predictive analytics can be used to predict things such as how likely a customer is to churn, or what the probability is that a particular disease will occur in a population.
