Implement GPU based DBSCAN clustering algo

21

Original serial algo: https://www.aaai.org/Papers/KDD/1996/KDD96-037.pdf GPU based implementations: 1. CUDA-DClust: http://www.dbs.ifi.lmu.de/Publikationen/Boehm/CIKM_09.pdf. It uses a collision matrix approach to name clusters. also has an index data structure on GPU that helps reduce...

[FEA] Add support for computing feature_importances in RF

14

**Is your feature request related to a problem? Please describe.** RF implementation should support computing `feature_importances_` property, just like how it is exposed in [sklearn](https://scikit-learn.org/stable/modules/generated/sklearn.ensemble.RandomForestClassifier.html#sklearn.ensemble.RandomForestClassifier.feature_importances_). **Describe the solution you'd like**...

Use RAFT communicator instead of a separate communicator in WholeMemory

2

PR #3 introduces `include/whole_memory.h` which currently seems to have its own communicator. In the future, we should be using the raft communicator handle instead.

Usage of C10 API's in WholeMemory and its implication on build

2

@BradReesWork JFYI... Currently, WM directly uses C10 API's from pytorch. Eg: `wholegraph/torch/whole_nccl_pytorch_tensor.h`. This means, similar to the pytorch backend of cugraph-ops, we'll also have to think about the topic of...

[DEBT] rename .h|.hpp|.cuh|.cu|.cpp files properly in our cuml C++ source base

Currently, they are just all over the place! I propose the following rule-of-thumb: 1. If a header file contains cuda kernels and/or device methods, then it should be a `.cuh`....
