TL;DR
The experimental results achieved an accuracy of 96.75%, precision of 94.65%, recall of 93.82%, and F1-score of 94.23%, demonstrating that Random Forest is effective for identifying anomalous conditions in smart home IoT environments.
Abstract
The increasing adoption of Internet of Things (IoT) technology in smart home environments generates large volumes of dynamic and heterogeneous multi-sensor data, creating challenges in accurately detecting anomalous conditions. This study aims to implement and evaluate the Random Forest algorithm for anomaly detection in IoT-based smart home systems using multi-sensor data. The dataset consists of temperature, humidity, light, motion, carbon monoxide (CO), liquefied petroleum gas (LPG), smoke, door/window status, and energy consumption collected from three IoT devices. Data preprocessing included cleaning, labeling, and Min-Max Scaling normalization, followed by an 80:20 training-testing split. Model performance was evaluated using a confusion matrix, accuracy, precision, recall, and F1-score. The experimental results achieved an accuracy of 96.75%, precision of 94.65%, recall of 93.82%, and F1-score of 94.23%, demonstrating that Random Forest is effective for identifying anomalous conditions in smart home IoT environments.
A novel hybrid multimodal approach called RF–LSTM–ANN which combines the Random Forest model for feature selection, the Long Short-Term Memory (LSTM) model for temporal dependency modeling and the Artificial Neural Network model for nonlinear binary classification is suggested.
The rapid proliferation of Internet of Things (IoT) devices has resulted in massive, heterogeneous, and high-velocity data streams, making accurate data management and device classification increasingly challenging—especially under class imbalance. This study proposes a lightweight and scalable classification pipeline...
