We conducted a statistically supported assessment of these categorical encoders using synthetic data and compared the encoders' performance. The results show that CESAMO outperforms all other evaluated encoding techniques, confirming its ability to identify patterns in cate...
TheCategoricalEncoderclass has been introduced recently and will only be released in version0.20. So if you install scikit-learn directly from the git repository you'll have it, otherwise, you'll have to wait for the next release! 😄 ...
All of the encoders are fully compatible sklearn transformers, so they can be used in pipelines or in your existing scripts. Supported input formats include numpy arrays and pandas dataframes. If the cols parameter isn't passed, all columns with object or pandas categorical data type will be...

Measuring the Effect of Categorical Encoders in Machine Learning Tasks Using Synthetic DataMost of the datasets used in Machine Learning (ML) tasks contain categorical attributes. In practice, these attributes must be numerically encoded for their use in supervised learning algorithms. Although there ...
Computer systems and methods generate a stochastic categorical autoencoder learning network (SCAN). The SCAN is trained to have an encoder network that outputs, subject to one or more constraints, parameters for parametric probability distributions of sample random variables from input data. The ...
