Data Preprocessing Screen

This screen allows you to perform data scaling. Data scaling is performed using the following formula. The values of ‘a’ and ‘b’ vary depending on the scaling method.

In=(Io-a)b
In: Scaled values
Io: Original values

1. Standardization: #

   ・Method: Scaling to have a mean of 0 and a standard deviation of 1
   ・a: Mean of Io
   ・b: Standard deviation of Io

2. Max-Min Normalization: #

   ・Method: Scaling the data to a range between 0 and 1
   ・a: Minimum value of Io
   ・b: Maximum value of Io – minimum value of Io

3. Abs-max Normalization: #

   ・Method: Scaling the data to have a maximum absolute value of 1 while keeping 0 as 0
   ・a: 0
   ・b: Maximum absolute value of Io

4. None: #

   ・Method: No scaling applied; original values are used as-is
