help me polish the english with the academic styleIn the processing of extracting potential leakage candidates the algorithm firstly establish background model then based on the established backgroun

candidates. The algorithm then applies a series of filtering techniques to further refine the potential leakage candidates and reduce false positives. Finally, the remaining candidates are analyzed and evaluated to determine their likelihood of being actual leakage points. This approach allows for efficient and accurate detection of potential leakage in complex systems.
