thvasilo opened a new issue #157: URL: https://github.com/apache/incubator-datasketches-cpp/issues/157
Hello, There's a consideration at [XGBoost](https://github.com/dmlc/xgboost/issues/5746) about potentially using the KLL sketch to represent feature value histograms. One potential blocker is the need for a weighted version of the sketch, this would allow us to use data points that are weighted, and adjust their feature contributions accordingly (See Appendix A of [XGBoost paper](https://arxiv.org/abs/1603.02754)). I remember discussing in the past the possibility of using data weights with KLL, is that still an option? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
