Seasonal
¶ Bases:
getml.preprocessors.preprocessor._Preprocessor
Seasonal extracts seasonal data from time stamps.
The preprocessor automatically iterates through all time stamps in any data frame and extracts seasonal parameters.
- These include:
year
month
weekday
hour
minute
The algorithm also evaluates the potential usefulness of any extracted seasonal parameter. Parameters that are unlikely to be useful are not included.
