Creating dummy datasets available in QXMT

[kenya-sk]

Task Overview

QXMT provides an environment where users can easily test various datasets through the configuration settings. One of these options is a dataset generated from dummy data of an arbitrary sample size, located at qxmt/datasets/dummy. Currently, only linearly separable dummy datasets are available, but other types of dummy datasets have been proposed.

Therefore, in this issue, I would like you to create a function that generates additional dummy datasets. The function should be callable via the configuration (e.g., configs/template-generate.yaml).

Implementing Process

1. Implement the generate function for the new dummy dataset in qxmt/datasets/dummy/xxxx.py.
2. Add test code in tests/datasets/dummy/test_xxx.py.
3. Check functionality by updating the config file and executing the run() method of QXMT
