Definition of Prediction Prediction: A prediction is a statement made about the future, typically based on data and statistical models. In data science, this is often done through the use of machine learning algorithms that are trained on historical data.
Definition of Upstream Upstream: Upstream and Downstream are terms used in data science to describe the flow of data or what order events occur. Data is processed and becomes more refined as it moves through the various processes. Upstream is closer to the source. When discussing a specific process step, Downstream is a term that…
Definition of T-distribution The t-distribution is a type of probability distribution that is used to calculate the likelihood of an event occurring. It is a bell curve-like distribution that is used to calculate the standard error of a statistic.
Definition of Spearman’s Rank Correlation Coefficient Spearman’s Rank Correlation Coefficient: Spearman’s Rank Correlation Coefficient is a measure of the strength of a linear relationship between two sets of data. It is calculated by taking the sum of the products of the ranks of corresponding values in each data set, divided by the product of the…
Definition of Gradient Descent Gradient descent is a popular optimization algorithm used in machine learning and data science. The goal of gradient descent is to find the minimum value of a function by systematically decreasing its value in each iteration. The algorithm takes as input an initial guess for the solution, and the derivative of…
