How to calculate Bhattacharyya coefficient?
The Bhattacharyya distance is defined as DB(p,q)=−ln(BC(p,q)), where BC(p,q)=∑x∈X√p(x)q(x) for discrete variables and similarly for continuous random variables.
Is Ganguly a Brahmin?
Ganguly (also called Ganguli, Ganguly, Gangulee, Gangoly or Gangopadhyay) is an Indian family name of a Bengali jijhotia Brahmin caste; it is a variant of Gangele Gangopadhyay(a) Gônggopaddhae.
What is chi-square distance explain with example?
Chi-square distance calculation is a statistical method, generally measures similarity between 2 feature matrices. Such distance is generally used in many applications like similar image retrieval, image texture, feature extractions etc.
Is Dixit a Brahmin?
The Dikshit/Dixit surname is usually associated with Hindu Brahmins in India especially in Northern India and Nepal. Dixit Brahmins are residing in the Uttar Pradesh, Uttrakhand, Punjab, Haryana, Madhya Pradesh, Jharkhand, Bihar and many of them belong to “Kaanya Kubja” lineage, some are there in Maharashtra also.

How is the Bhattacharyya coefficient used in statistics?
Bhattacharyya coefficient. The Bhattacharyya coefficient is an approximate measurement of the amount of overlap between two statistical samples. The coefficient can be used to determine the relative closeness of the two samples being considered.
Which is the upper bound of Bhattacharyya distance?
Bhattacharyya bound: If we do not insist on the optimum selection of s, we may obtain a less complicated upper bound. One of the possibilities is to select s = 1/2. Then, the upper bound is (3.152) μ (1/2)=1 8(M 2 − M 1) T(Σ1 + Σ2 2) − 1 (M 2 − M 1) + 1 2ln |Σ1 + Σ2 2 | √ |Σ1| |Σ2| .
How to calculate the Bhattacharyya distance for discrete variables?
The Bhattacharyya distance is defined as D B (p, q) = − ln (B C (p, q)), where B C (p, q) = ∑ x ∈ X p (x) q (x) for discrete variables and similarly for continuous random variables.
Is the Bhattacharyya distance a measure of similarity?
In statistics, the Bhattacharyya distance measures the similarity of two probability distributions. It is closely related to the Bhattacharyya coefficient which is a measure of the amount of overlap between two statistical samples or populations.
