Inventory Khiops Type Coercion Cases and Implement Sklearn-Side Policy Accordingly #232

Closed popescu-v closed 1 week ago

popescu-v commented 3 months ago

Description

Currently, in estimator methods like _check_dictionary_compatibility, numerical types are coerced to categorical types. However, other type incompatibilities are not coerced and error is raised. One needs to check whether other coercion cases are possible, viz.:

among the Date / Time / Timestamp types

Possibly not a problem:

In-memory dataset: The target's types are checked before being passed to Khiops. So an error would be reported.
File dataset: If the column cannot be converted to the target's type (either Numerical or Categorical) then Khiops will report an error.

This is already handled inherently.
