Corrigendum Notice: Motion Fusion: A Robust Ensemble Learning Framework for Accurate Sensor-Based Human Activity Recognition

NOTICE OF CORRIGENDUM FOR: Almulla, Hussein K.; Mohammed, Hussam J.; Al-Waisy, Alaa S.; Al-Fahdawi, Shumoos; Had, Ahmed Adnan; and AL-Attar, Bourair (2025) ``MotionFusion: A Robust Ensemble Learning Framework for Accurate Sensor-Based Human Activity Recognition,'' Iraqi Journal for Computer Science and Mathematics: Vol. 6: Iss. 3, Article 14. DOI: https://doi.org/10.52866/2788-7421.1289. Available at: https://ijcsm.researchcommons.org/ijcsm/vol6/iss3/14. Reason for Corrigendum: In the published version of the above article, a number of typographical and formatting errors were identified. These corrections do not affect the study design, results, or conclusions, and are provided below to ensure accuracy and consistency. 1) Feature subset sizes (text–table inconsistency) Error: The manuscript contains inconsistent feature subset sizes. While the feature-selection setup defines subsets as 420 / 280 / 140 (≈ 75% / 50% / 25% of 561), another sentence incorrectly reports 300 and 100 for 50% and 25%. Correction: The correct subset sizes are: 75%: 420 features 50%: 280 features 25%: 140 features Accordingly, the sentence reporting ``50% (300)'' and ``25% (100)'' should be corrected to
