描述

Since there doesn't seem to be a mention of the reverse_string_indexer in mleap/python/mleap/sklearn/preprocessing/, I don't believe the ReverseStringIndexer is currently supported for sklearn.

研究方向
Investigate the existing transformer support in mleap/python/mleap/sklearn/preprocessing/ to understand the pattern for adding new transformers. Look at how other transformers like StringIndexer are implemented. Then implement ReverseStringIndexer following the same pattern, ensuring serialization/deserialization in both sklearn and MLeap bundles.
