Bias and Variance is the common words which we will hear in Machine Learning. Bias: we will see this issue more in parameter Machine Learning algorithms, because most of the parameter algorithms are liner/polynomial, so It will not touch/read all data points, so we will have more error, which leads to under fitting.If you seeContinue reading “Bias-Variance and trade off”

Variance and Standard Deviation
Variance Variance is a measurement of the spread between numbers in a given data set. Below is the formula to calculate Variance ,just remember we need to use n-1(where n is count of observations/population/sample) in when we are using sample (click here to know about Sample vs Population). Standard deviation: Standard deviation measures the spread ofContinue reading “Variance and Standard Deviation”
correlation
In general correlation means the relation between two different entities will come under Bi varient analysys . In this blog we will discuss about below item. Co Variance correlation coefficient Coefficient of Variation Covariance: Covariance is a measure of how much two random variables/datasets vary together or When we want to understand the linearity betweenContinue reading “correlation”
