Webetc. Data mining techniques can effectively predict the rainfall by extracting the hidden patterns among available features of past weather data. This research contributes by providing a critical analysis and review of latest data mining techniques, used for rainfall prediction. Published papers from year 2013 to 2024 WebIn this paper, we conducted a detailed analysis on how the data preprocessing stages afect fairness in ML pipelines. Prior research observed that bias can be encoded in the data itself and missing the opportunity to detect bias in earlier stage of ML pipeline can make it diicult to achieve fairness algorith-mically [22, 31, 35, 44]. bits xplore login https://grupomenades.com
