Add single precision support for roc_auc_score

2

As of now, DAAL only support double precision calculation of the roc_auc_score. A single precision implementation in https://github.com/oneapi-src/oneDAL/blob/main/cpp/daal/src/data_management/roc_auc_score.cpp is necessary for conformance to the datatypes in the DAAL codebase.

How to convert a trained LGBM model to DAAL model by CPP interfaces?

6

**Describe the bug** - In Python, we can simply use `daal4py.get_gbt_model_from_lightgbm()` to convert a trained LGBM model to oneDAL, and use `daal4py.gbt_regression_prediction()` to predict. - May I find the corresponding...
