Read MoreUnderstanding Types of Mean
Introduction The average value of a set of data points, observations, or values is known as the Mean of the data. It is the measure of the central tendency. Mathematically, the mean is obtained by dividing the sum of values by the number of values or observations. It is also called the expected value. The mean itself is not restricted to this simple form but has different types such as the arithmetic mean, geometric mean, harmonic mean, and weighted average. It is given mathematically as, $$\mathrm{Mean=\frac{\sum x}{N}}$$ where, x = set of observations N = number of observations Different ...
Read MoreTypes of Regression Techniques in Machine Learning
Introduction Regression is the technique of predictive modeling to analyze the relationship between the independent variable and the dependent variable. The relation between the target(dependent variable) and the independent variable may be either linear or non-linear. The target is always continuous value and regression is widely used in forecasting, understanding cause and effect as well as in predictive analysis. In this article let us explore various regression techniques available. Regression Techniques Linear Regression − It is the simplest of all regression techniques. In Linear Regression the independent and the target variable are linearly related or dependent on each ...
Read MoreHow to Encode/Decode URL using AngularJS ?
Handling URLs, which are used to move between various web pages and parts, is a fundamental component of web development.
