A Markov model is a mathematical model used to predict the probability of future events, based on the assumption that the past and present events have no bearing on the future. Markov models are named after Andrey Markov, who first developed them. What is Markov models in machine learning? A Markov model is a machine … Read more
A dependent variable is a variable that is affected by the independent variable. In an experiment, the dependent variable is the variable being tested and the independent variable is the variable being manipulated. What do you mean in dependent variable? In mathematics, a dependent variable is a variable whose value is determined by another variable. … Read more
A transcendental number is a real or complex number that is not algebraic, meaning that it cannot be the root of a non-zero polynomial equation with integer coefficients. The first transcendental numbers were discovered in the early 19th century, and their existence was not rigorously proven until 1844. The most famous transcendental numbers are e … Read more

A bar graph is a graphical representation of data using rectangular bars of different heights or lengths. Bar graphs are widely used in statistics, business, and economics. They are often used to compare data from different groups, or to show changes over time. Why are bar graphs used? There are many reasons why bar graphs … Read more
An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined as the square root of -1. Imaginary numbers are often used in mathematical and scientific contexts to represent complex numbers. The term “imaginary number” is used to describe a number that … Read more
A real number is a value that represents a quantity along a continuous line. Real numbers can be positive or negative, and include such values as 1, 2, 3, 4, 5, -1, -2, -3, -4, -5, 0.5, 1.5, 2.5, and so on. Real numbers can also be represented using decimal notation, such as 3.14159 for … Read more
The percent change (percent difference) between two values is a measure of the relative change between those values. It is calculated as a percentage, using the following formula: Percent change = (new value – old value) / old value * 100 For example, if the old value is 10 and the new value is 12, … Read more
