🚀 Feature Request

Replace RDD-based operations in metric calculation with UDF to replace with Scala UDF in future

Motivation

Metrics calculation speed up

will it work on Windows11 for example LightFM
LightFM
classreplay.models.LightFMWrap(no_components=128, loss='warp', random_state=None)
Wrapper for LightFM.

🚀 Feature Request

Add .count() just after cache methods in all place

Motivation

It is needed for more honest estimation of execution time

Work with bigger data volumes, Update model without re-fit.

🚀 Feature Request

Find out how to preprocess and pass model weights/vectors to Kafka

Motivation

Models inference

🐛 Bug

UserSplitter неисправно работает c параметром user_test_size

To Reproduce

data_frame = pd.DataFrame({"user_idx": [1,1,1,2,2,2],
"item_idx": [1,2,3,1,2,3],
"relevance": [1,2,3,4,5,6],
"timestamp": [1,2,3,3,2,1]})

data_frame = convert2spark(data_frame)

UserSplitter(2,1,seed=80083).split(data_frame)[0].toPandas()

🐛 Bug

I have 'user_id' column in my data, so when I try to use some of the methods or functions, I get this error:
pyspark.sql.utils.AnalysisException: cannot resolve 'user_idx'

To Reproduce

Examples where 'user_idx' column is required:
replay/models/base_rec.py", line 321, in _fit_wrap users = log.select("user_idx").distinct()

replay/filters.py", line 28, in min_entries entries_by_user = data_frame.groupBy("user_idx").count() # type: ignore
