[P] Just finished a C++ library for training decision trees on Arduino-compatible boards

The library is called TinyDecisionTreeClassifier and it's interface mimics the DecisionTreeClassifier from scikit-learn. There are some examples available, and I have actually managed to train Nrf52840 to recognize physical activity(stand/sit/walk). It would be quite interesting to check, if it can be used to for classifying machinery failure based on vibration or for human stress detection from PPG (As in smartwaches).

The library is now available from PlatformIO registry or this repo: [https://github.com/allexoK/TinyDecisionTreeClassifier](https://github.com/allexoK/TinyDecisionTreeClassifier)
