Definition of N-gram
An n-gram is a contiguous sequence of n items from a given text or speech. N-grams are used to study linguistic patterns and to generate text samples.

Definition of Linear Regression Linear Regression: Linear Regression is a statistical technique that helps us understand how one variable (the dependent variable) changes when other variables (the independent variables) change. It does this by fitting a line through a set of data points, and then using the line to predict the value of the dependent…
Definition of Mathematical Statistics Mathematical Statistics: Mathematical statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It also provides techniques for estimating properties of populations from samples. Mathematical statistics is distinguished from other statistical techniques in that it relies on mathematical theory as a foundation. What…
A categorical variable is a data type that represents qualitative information. For example, colors (red, blue, green), genders (male, female), and religions (Catholic, Protestant, Muslim) are all categorical…
Definition of Dependent Variable A dependent variable (also called the response variable) is a variable whose value is determined by the value of one or more other variables (the independent variables). The dependent variable is usually the focus of a data analysis, since it is the quantity that is being measured or estimated. What is…
Definition of Jaccard Index Jaccard Index: The Jaccard Index is a statistic used to measure the similarity of two sets. It is calculated by dividing the number of elements in both sets that are common to both sets by the total number of elements in both sets. What is Jaccard Index used for? The Jaccard…
Definition of Markov Chain A Markov chain is a mathematical model for sequences of random events, where the probability of any event depends only on the immediately preceding event. How is Markov Chain used? Markov Chain is a type of machine learning algorithm that uses probability to model complex systems. It is based on the…
