Özet

In this study, anomaly detection is investigated under controlled noise injection using IMU sensor data collected from a mobile robot. The collected time-series data is processed using a windowing approach, and machine learning models are developed based on extracted features. Logistic regression and random forest algorithms are employed for anomaly detection, and SHAP is used to enhance model interpretability. In addition, the impact of different window sizes on model performance is analyzed. Experimental results indicate that window size has a significant impact on model performance.
