Support Vector Machine Versus Random Forest for Remote Sensing Image Classification: A Meta-Analysis and Systematic Review
Overview
Paper Summary
The meta-analysis compared Random Forest (RF) and Support Vector Machines (SVM) for remote sensing image classification across 251 studies. While both methods are widely used and achieve high accuracies, RF showed a recent surge in popularity, possibly due to its robustness and ease of use, and often outperformed SVM in applications like land cover mapping with larger datasets and higher resolution imagery.
Explain Like I'm Five
Scientists found that two smart computer ways to sort pictures, called RF and SVM, are both good. But RF is becoming more popular because it's easier and often better for really big, detailed pictures, like maps from space.
Possible Conflicts of Interest
The authors declare that there is no conflict of interest regarding the publication of this paper. However, the funding acknowledgement suggests a potential connection to the European Union's Connecting Europe Facility Telecom Project, although it's unclear how this might influence the research.
Identified Limitations
Rating Explanation
This meta-analysis provides a valuable overview of the use of RF and SVM in remote sensing image classification, summarizing findings from numerous studies. Although the comparison relies on reported accuracies, which can be subject to variation, the study offers useful insights into the relative performance and application trends of these algorithms. The recommendations for future research are also valuable.
