Definition of Machine Learning Model A machine learning model is a representation of the data that is learned by a machine learning algorithm. The model can be used to predict the outcomes of future events, based on the data that is used to train the model. How is Machine Learning Model used? A Machine Learning…
Definition of Logistic Regression Logistic regression is a machine learning algorithm used for classification and regression analysis. It is a type of linear regression, where the outcome variable is categorical rather than continuous. Logistic regression is used to predict the probability of a particular event occurring, such as whether or not a customer will churn….
Definition of Logarithm The logarithm is a mathematical function that calculates the power to which a base number must be raised to produce a given number. It is written as log(x) and is read “log of x.” How is Logarithm used? Logarithm is a mathematical operation used to calculate the power or exponent that a…
Definition of Lift Lift is a measure of how much a model predicts the value of a target variable relative to the prediction of the same target variable by a random guess. Lift is often used as a measure of how good a model is at discriminating between different groups. How is Lift used? Lift…
Definition of K-Nearest Neighbors K-Nearest Neighbors (KNN) is a machine learning algorithm used to predict the output value of a target variable by finding the k nearest neighbors of a given input value. The algorithm assigns a weight to each neighbor, then uses a weighted average to predict the output value for the target variable….
Definition of JavaScript JavaScript is a programming language that enables developers to create complex websites and applications. JavaScript code is executed in the browser, which makes it a powerful tool for front-end development. Additionally, JavaScript can be used to create back-end functionality with Node.js. An Introduction to JavaScript in the Field of Data Science and…
Definition of Independent Variable An independent variable is a variable that is manipulated by the experimenter in a scientific study. It is typically one factor that is changed while all other factors are kept constant. What is an Independent Variable used for? An independent variable is a type of variable used in statistical models and…
Definition of Histogram A histogram is a graphical representation of the distribution of data. It is created by dividing the range of data into a series of equal intervals, and then counting the number of data points that fall into each interval. What is a Histogram used for? A histogram is a graphical representation of…
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…
Definition of GATE GATE is an acronym for “General Architecture for Text Engineering.” GATE is an open-source software development kit for research and development of advanced natural language processing (NLP) applications. What is GATE used for? GATE (General Architecture for Text Engineering) is a software framework developed by the University of Sheffield in 2000 that…
