Euclidean Distance Score It is a simple method to calculate distance between two points in space. Single dimension ( x ) 2D ( x,y ) 3D ( x,y,z ) (x 2 , y 2 , z 2 ) (x 1 , y 1 , z 1 )

It is a simple method to calculate distance between two points in space.

Single dimension ( x )

2D ( x,y )

3D ( x,y,z )

Mark the points first (x 2 , y 2 , z 2 ) (x 1 , y 1 , z 1 ) d

Euclidean Distance Formula Distance, d = √ (x 2 -x 1 ) 2 + (y 2 -y 1 ) 2 +(z 2 -z 1 ) 2 (x 2 , y 2 , z 2 ) (x 1 , y 1 , z 1 ) d

Distance, d = √ (x 2 -x 1 ) 2 + (y 2 -y 1 ) 2 +(z 2 -z 1 ) 2

Wait a minute! how geometry and actual People in a web app are related?

Ratings Shivaji TZP User 1.5 4 John 4.5 1.5 Ravi 1 3.5 Kiran 3 5 Deepti

How to calculate? Distance, d = √ (x 2 -x 1 ) 2 + (y 2 -y 1 ) 2 D(John, Ravi) = √ (1.5-4.5 ) 2 + (4-1.5 ) 2 = √ (3 ) 2 + (2.5 ) 2 = 3.91

Distance, d = √ (x 2 -x 1 ) 2 + (y 2 -y 1 ) 2
