Binning Methods for Data Smoothing in data mining

What is the binning method?

Binning method can be used for smoothing data.

Example:

Sorted data for Age:   3, 7, 8, 13,        22, 22, 26, 22,      26, 28, 30, 37

How to smooth the data by equal frequency bins?

  • Bin 1: 3, 7, 8, 13
  •  Bin 2: 22, 22, 22, 26
  •  Bin 3: 26, 28, 30, 37
[quads id=1]

How to smooth the data by bin means?

  •  Bin 1: 10, 10, 10, 10
  • Bin 2: 23, 23, 23, 23
  • Bin 3: 30, 30, 30, 30

 

How to smooth the data by  bin boundaries?

  • Bin 1: 3, 3, 3, 13
  • Bin 2: 22, 22, 26, 26
  • Bin 3: 26, 26, 26, 37
