Built upon the MobileNet architecture, GRMobiNet introduces targeted modifications to enhance predictive accuracy without increasing model size and computational complexity. To validate the performance gains, a series of controlled experiments were conducted using a custom dataset comprising ten image categories, with each model evaluated across ten repeated runs on identical test sets. A paired samples t-test was applied to compare the classification accuracy of GRMobiNet and MobileNetV2 under identical experimental conditions. Results indicate that GRMobiNet achieved a mean accuracy of 80%, significantly outperforming MobileNetV2’s 57%, with a mean improvement of 2.3 correctly predicted images per run. The observed p-value of 0.019 confirms statistical significance at the 95% confidence level. Moreover, GRMobiNet exhibited lower variance and a reduced standard error of the mean, indicating greater stability across trials. These findings confirm that GRMobiNet offers not only computational efficiency, but also statistically validated performance superiority, making it highly suitable for real-world deployment in domains such as mobile diagnostics, precision agriculture, and embedded surveillance systems. The statistical rigor of this validation underscores GRMobiNet’s robustness and reliability as an advancement over existing lightweight architectures.

Although DNNs are excellent in many applications, their deployment on devices like wearables and mobile phones presents significant challenges. The study investigates six popular DNN models, including MobileNet (V1 and V2), ResNet50, InceptionV3, DenseNet121, and EfficientNetB1. To assess each model's advantages, disadvantages, usability, and effectiveness in RCE scenarios, a comprehensive review and empirical analysis were conducted. The analysis focuses on optimizing these models to function effectively given the limited computational power and memory of RCE devices. Key factors such as model size, computational complexity, and inference speed are examined to uncover performance trade-offs between accuracy and resource efficiency. The findings suggest that MobileNetV1 should serve as baseline models for building efficiency-focused DNN models for image classification on RCE devices. This recommendation is based on MobileNetV1's balance between performance and efficiency, making it an ideal starting point for further optimization.

The systematic evaluation encompasses ten state-of-the-art pre-trained DNN models: ResNet50, InceptionResNetV2, InceptionV3, MobileNet, MobileNetV2, EfficientNetB0, EfficientNetB1, EfficientNetB2, DenseNet121, and Xception, within the context of an RCE setting. Evaluation criteria, such as parameters (indicating model complexity), storage space (reflecting storage requirements), CPU usage time (for real-time applications), and accuracy (reflecting prediction truth), are considered through systematic experimental procedures. The results highlight MobileNet's excellent trade-off between accuracy and resource requirements, especially in terms of CPU and storage consumption, in experimental scenarios where image predictions are performed on an RCE device. Utilizing the identified baseline model, a new model, GRM-MobileNet, was developed by implementing compound scaling and global average pooling techniques. GRM-MobileNet exhibits a substantial reduction of 23.81% in parameters compared to MobileNet, leading to a model size that is 23.88% smaller. Moreover, GRM-MobileNet demonstrates a significant improvement in accuracy, achieving a remarkable gain of 28.12% over MobileNet. Although the enhancement in inference time for GRM-MobileNet compared to MobileNet is modest at 1.66%, the overall improvements underscore the effectiveness of the employed strategies in enhancing the model's performance. A future study will examine other model optimization strategies, including factorization and pruning, which ultimately lead to faster inference without compromising accuracy, in an effort to improve the efficiency of the GRM-MobileNet model and its inference time.
