In statistical analysis of binary classification, the Harmonic mean in ML is a measure of a test’s accuracy and is known as F1 score or subcontrary mean. The F1 score (Harmonic mean) is combined by using the recall and the precision , and is better then taking the arithmetic meanContinue Reading
R Squared is the coefficient of determination it normally ranges from 0 to 1, and provides a measure of how well observed outcomes, are replicated by the model. The formula is: Residual(Error) sum of squares (RSS), also known as (SSR) , is the sum of the squares of theContinue Reading
Radiance (L)- light carried by a ray from a light source. 1 Watt(W) = 1 Joule per second. A radian(r) is a measure of an angle, a steradian/ square radian[(sr) is a measure of a solid angle. e.g. In a cone it’s the amount of the radian area of the cone. IrradianceContinue Reading
