Supplementary material - An Optimized Gradient Boosting Framework for IoT Intrusion Detection: A Comprehensive Evaluation on the CICIoT2023 Dataset

This repository provides the complete supplementary material for the study “An Optimized Gradient Boosting Framework for IoT Intrusion Detection: A Comprehensive Evaluation on the CICIoT2023 Dataset.”

It includes three preprocessed feature-selected datasets — Binary, Eight-Class, and Thirty-Four-Class — derived from the CICIoT2023 benchmark using stratified undersampling and LightGBM-based feature selection. These datasets contain only the discriminative features used in the experiments and are ready for direct model reproduction without further preprocessing.

Each classification level is accompanied by:

• A comprehensive Excel results file (*_Classification_FullResults.xlsx) summarizing class distributions, feature importance, model performance reports, confusion matrices, inference latency, and overall accuracy/F1 summaries.

• A reproducible experiment script (*_Classification_Experiment.py) that automates the entire workflow — including data loading, normalization, model training (XGBoost, LightGBM, CatBoost), and evaluation.

Original data were obtained from the CICIoT2023 dataset by the Canadian Institute for Cybersecurity (UNB).
