DETECTION OF VR IMPACT ON HUMANS USING NAIVE BAYSE MODEL
Abstract
Human activity recognition (HAR), as an important research issue, aims to identify human activities in smart homes. In this paper, we apply Gaussian Naive Bayes (GNB) algorithm to HAR and evaluate the model based on smart environment sensor data. Experimental results show that the effective selection and processing of features are helpful to improve the accuracy of activity recognition of the model. Compared with NB whose accuracy rate is 82.7%, GNB has a better accuracy rate of 89.5% and even has a higher recognition accuracy in almost every category of activities. Selecting the feature variables as good and useful as possible to get a better model in the process of activity recognition is conducive to the correct classification of samples by machine learning algorithm and improves the classification performance of the model.The Naive Bayes model is a probabilistic classifier based on Bayes' Theorem with the naive assumption of independence between every pair of features. This model is particularly useful for large datasets and is known for its simplicity, efficiency, and often surprising accuracy, especially in text classification and medical diagnosis problems.

Relevance and Originality
The study addresses the growing importance of human activity recognition (HAR) in smart home environments, highlighting its relevance in enhancing user experience and automating home systems. The application of the Gaussian Naive Bayes (GNB) algorithm to HAR presents a novel approach, particularly in evaluating its effectiveness against the traditional Naive Bayes (NB) classifier. The originality of the research lies in its focus on feature selection and processing, which are critical in improving the accuracy of activity recognition. By demonstrating the advantages of GNB over NB, the study contributes valuable insights into the development of more effective HAR systems in smart homes.
Methodology
The methodology employed in the study is well-structured, utilizing smart environment sensor data to evaluate the performance of the GNB algorithm in HAR. The emphasis on feature selection and processing is commendable, as it directly influences the model's accuracy. However, the paper could benefit from more detailed descriptions of the dataset used, including the number of samples, types of activities recognized, and the specific sensors involved. Additionally, the article should elaborate on the feature selection process, such as which features were considered and how they were processed, to provide a clearer understanding of the methodology's robustness.
Validity & Reliability
The validity of the research is supported by the comparative analysis between the GNB and NB algorithms, with a notable increase in accuracy from 82.7% to 89.5%. This improvement demonstrates the effectiveness of GNB in HAR applications. However, to strengthen the reliability of the findings, the study should incorporate statistical tests to validate the significance of the performance differences observed between the two algorithms. Including cross-validation techniques would also enhance the robustness of the results and ensure that the findings are generalizable across different datasets and scenarios.
Clarity and Structure
The article is generally well-structured, presenting a clear flow from the introduction of HAR to the discussion of the GNB algorithm and its application. Key concepts are articulated in a straightforward manner, making the research accessible to a broad audience. Nevertheless, the inclusion of visual aids, such as charts or graphs illustrating accuracy comparisons and feature importance, would enhance clarity. A dedicated conclusion section summarizing the key findings and implications for future research would provide readers with a concise overview of the study's contributions.
Result Analysis
The result analysis effectively highlights the improvements in activity recognition accuracy achieved through the application of the GNB algorithm. By presenting the comparative accuracy rates, the study successfully showcases the benefits of the GNB model. However, the analysis could be enriched by providing specific examples of activity classifications and their corresponding accuracy rates, offering a deeper understanding of the model's performance across different activity types. Discussing potential limitations or challenges encountered during the evaluation process would also add depth to the analysis and suggest avenues for future research. Overall, the research presents a promising application of GNB in HAR, indicating its potential for practical implementation in smart home systems.
