Comparative study of boston house price prediction models based on gan data augmentation
He, Runhai (БНТУ, 2024)This study aims to compare the performance of four machine learning models in the Boston housing price prediction task, and explore whether GAN data augmentation can improve the prediction performance of the model. Experimental results indicate that on the original data set, The CatBoost model demonstrated superior predictive performance, with an MSE of 4.76, RMSE of 2.18, MAE ...2025-04-21 -
Enhancing heart disease prediction using gaussian process regression and sequential analysis for optimal sampling efficiency
He, Runhai; Li, Fusheng; Zhang, Zhenxing; Zhang, Shoujing (БНТУ, 2024)Heart disease poses a significant risk to global health, and accurate prediction of this risk is critical to public health. This study leverages the Kaggle heart disease dataset, employs machine learning models to predict heart disease risk, and introduces sequence analysis to minimize sample collection while maintaining accuracy. Of the four models, linear regression, Bayesian ...2025-04-21 -
Realizing real-time video conferencing system based on WebRTC and P2P algorithm
He, Runhai; Cheng, Yindong; Zhang, Zhenxing; Zhou, Quanhua (БНТУ, 2023)This paper presents a solution for realizing a real-time video conferencing system, which utilizes WebRTC technology and P2P algorithm to establish a distributed topology that reduces the burden on servers and allows direct communication between nodes. The ABR algorithm is used to adjust the video bit rate to adapt to different network conditions. In addition, optimization ...2024-01-23 -
Vegetation index methods: a comparative analysis of NDVI, EVI and SAVI
Zhang, Shoujing; He, Runhai; Li, Fusheng; Zhang, Zhenxing (БНТУ, 2024)This study emphasizes the importance of monitoring and predicting plant functional traits for ecological and agricultural research, particularly in the context of climate change. Hyperspectral remote sensing is a key tool for studying vegetation health and ecosystem dynamics due to its efficiency and wide coverage. Common modeling methods include vegetation indices, partial least ...2025-04-21
