FrequencyEncoder
This transformer is deprecated. Consider using the UniformEncoder instead.
Compatibility: categorical data
The FrequencyEncoder transforms data that represents unordered, categorical values into decimals in the range [0, 1]. This range is broken up into separate intervals for each category -- more popular categories take up larger intervals.
Parameters
add_noise: Add noise when transforming a category into the [0, 1] interval.
(default) | Do not add noise. Each time a category appears, it will always be transformed to the same value. |
| Add noise. A category may be transformed to different values every time it appears (but it will always stay within the interval). |
