Sadly but evaluation metrics are only implemented in pyspark.mllib (RDD API) but not in pyspark.ml (Dataframe API) Also worth mention about implicit feedback

- yueguoguo1024 8y agoIt is also my sadness - AFAIK pyspark.ml does not support ranking metrics (does it?). So we wrapped the RDD and expose data frame as interfaces in our own implementations (the `reco_utils`). Implicit feedback is mentioned in a notebook under `staging` branch (https://github.com/Microsoft/Recommenders/blob/staging/notebooks/01_prepare_data/data_transform.ipynb https://github.com/Microsoft/Recommenders/blob/staging/noteb...). Will be there soon in the next release (1st of Feb)!
