we discussesed Saurabh's xapp proposal for ad-cell. Thoralf to sedn reminder to Sunil.

Bimo asked for KPImon xapp - how to get latest source code that support E2SM KPM v2.0. Amit commented earlier that this is supported, and was used in a demo, but not possible to find source code. Please, send a reminder to Amit/Deepanshu deepanshu.k@h.. and also include James )lijianyj@ch...) and Thoralf (thoralf.czichy@n..). link to the video referred to: Contributions .

Saurabh (and Saravanan) (Samsung): new repo for AD due to too many changes in existing xApp. New repo needed. Check from OSC main mailing list on propsoal for new repo.

Deepanshu: commented that indeed existing AD (UE-level) is different from cell-level AD in new xApp and that's why there's a new repo.Sunil was planning to scheduke a call on this.

• Saravanan from Samsung team propose improvement in AD xApp in terms of improving the the ML model to improve the efficiency.

  • Following are the details : To Automate anomaly detection using Statistical/ML models to reduce effort to less then an Hour, we analysed multiple machine learning algorithms like Isolation Forest, CBLOF, KNN, OCSVM, XGBOOST, Random Forest. Among all machine-learning algorithms, XGBoost has performed well on seen and unseen data. Hence, we can say that XGBoost model can work on multiple circle in cellular network.
