Link Quality Estimation Base on CatBoost

2021 13th International Conference on Communication Software and Networks (ICCSN), 2021
To estimate link quality for wireless sensor networks (WSN) accurately and rapidly, an approach of link quality estimation is proposed, which is based on Category Boosting (CatBoost). Received signal strength indicator mean, link quality indicator mean and the signal to noise ratio mean are selected as the link quality parameters.

Shortest Path Distance Prediction Based on CatBoost

2021
Shortest path distances between node pairs on road networks are essential for many applications. Traditional methods, such as breadth first search (BFS) and Dijkstra algorithm, focus on precise result. However, they are difficult to apply to the large-scale road network because of the high time cost.

Performance of CatBoost and XGBoost in Medicare Fraud Detection

2020 19th IEEE International Conference on Machine Learning and Applications (ICMLA), 2020
Due to the size of the data involved, performance is an important consideration in the task of detecting fraudulent Medicare insurance claims. We evaluate CatBoost and XGBoost on the task of Medicare fraud detection, and report performance in terms of running time and Area Under the Receiver Operating Characteristic Curve (AUC).

CatBoost for Nonintermittent Demand in the Aviation Aftermarket

International Journal of Reliability, Quality and Safety Engineering
The demand for aircraft parts is often difficult to forecast, leading to challenges in maintenance planning, inventory management, and overall operational efficiency. In this invited paper, we examine monthly demand forecasting for used aircraft parts in the nonintermittent domain (Smooth and Erratic), with CatBoost as the ...

Accuracy Assessment of CatBoost for Storm Damage

PROCEEDINGS of 20th International Symposium on Applied Informatics and Related Areas
This paper explores the use of gradient boosting to quantify the economic damage caused by storms and classify storm events as severe or mild. The study draws on a historical disaster open database. These figures confirm gradient boosting’s high accuracy in analysing extreme meteorological events for insurance.

Automated Detection of Chagas Disease via CatBoost

Anais do XVII Congresso Brasileiro de Inteligência Computacional
Chagas disease, caused by Trypanosoma cruzi, is a neglected tropical disease that continues to pose a significant health threat in Latin America and is increasingly found in non-endemic regions due to migration. The chronic cardiac form of the disease (chronic Chagasic cardiomyopathy) often develops silently, making early detection difficult and ...
