GELİŞMİŞ GİYİLEBİLİR SENSÖR BİLGİSİ İŞLEME: İNSAN AKTİVİTESİNİN TANINMASI İÇİN OPTİMİZE EDİLMİŞ KALMAN FİLTRESİ

Öz

Bu çalışma, sinyal filtreleme ve tahmini için geleneksel ve gelişmiş Kalman filtresi yöntemlerini incelemektedir. İlk olarak sentetik sinüzoidal veriler kullanılmış, bunu insan aktivite sinyalleri izlemiştir. Başlangıçta, sentetik sinyaller üzerinde standart Kalman Filtresi (KF), Genişletilmiş Kalman Filtresi (EKF), Kokusuz Kalman Filtresi (UKF) ve otomatik olarak ayarlanmış parametrelere sahip Bayes-Optimize Edilmiş Kalman Filtresi'nin (Bayes-KF) filtreleme performansları araştırılmıştır. İnsan aktivite sinyalleri, UCI'nin İnsan Aktivitesi Tanıma (HAR) veri setinden elde edilen ivme verileri kullanılarak tahmin edilmiştir. Tahmin doğruluğu açısından, Bayes-KF yaklaşımı, filtre parametrelerini (Q ve R) iyileştirerek geleneksel KF, EKF ve UKF yöntemlerinden daha iyi performans göstermiştir. Her yaklaşımın performansını değerlendirmek için Ortalama Karesel Hata (MSE), Ortalama Karesel Hatanın Kökü (RMSE) ve Ortalama Mutlak Hata (MAE) göstergeleri kullanılmıştır. Bayes-KF yöntemi, MSE metriğine göre 5,0996 x 10-5 değeriyle en düşük tahmin hatasını üretti. Karşılaştırmalı çalışma, Bayes-KF'nin hem sentetik hem de gerçek dünyadaki insan aktivite sinyalleri için güvenilir bir yöntem olduğunu göstermektedir. Bu nedenle, hareket analizi ve sensör verisi işleme gerektiren uygulamalarda özellikle faydalıdır.

ADVANCED WEARABLE SENSOR INFORMATION PROCESSING: OPTIMIZED KALMAN FILTER FOR RECOGNITION OF HUMAN ACTIVITY

Öz

This study examines traditional and advanced Kalman filter methods for signal filtering and estimation. Synthetic sinusoidal data were first used, followed by human activity signals. Initially, the filtering performances of the standard Kalman Filter (KF), Extended Kalman Filter (EKF), Unscented Kalman Filter (UKF), and Bayesian-Optimized Kalman Filter (Bayes-KF) with automatically tuned parameters were investigated on synthetic signals. Human activity signals were estimated using acceleration data from the UCI's Human Activity Recognition (HAR) dataset. In terms of prediction accuracy, the Bayesian-KF approach outperformed the traditional KF, EKF, and UKF methods by improving the filter parameters (Q and R). Mean Square Error (MSE), Root Mean Square Error (RMSE), and Mean Absolute Error (MAE) indicators were used to evaluate the performance of each approach. The Bayesian-KF method produced the lowest prediction error, with a value of 5.0996 x 10-5 based on the MSE metric. The comparative study demonstrates that Bayesian-KF is a reliable method for both synthetic and real-world human activity signals. Therefore, it is particularly useful in applications requiring motion analysis and sensor data processing.
