The title says it. I was wondering if normalization has any effect on computing. Does normalization effect computing?

  • Integer calculation is much faster than floating point, but I'm not sure what do you mean with normalization. – Martheen Oct 06 '20 at 06:08

It is costlier to compute 0.02 * 0.02 compared to 2 * 2 has 2 * 2 is a single math operation where only one multiplication is involved. Floating point number are stored has 2*10^-2 format(scientific notation). Therefore, two operations are involved here,

  1. 2 * 2
  2. (-2) + (-2)

Thus, the answer is computed as 4 * 10^(-4) or 0.0004. Thus, 0.02 * 0.02 is costlier compared to 2*2.

    Thanks, I guess when we normalize mathematical values of features for machine learning we're increasing cost of computation. Am I right? – Sadaf Shafi Oct 07 '20 at 12:13
