This study focuses on the implementation and evaluation of several machine learning algorithms, specifically decision trees, random forests, and support vector machines, using the WEKA tool. These algorithms are employed to predict weather-related outcomes. To enhance the performance of these models, an optimized hybrid feature selection technique (PSO + RF) is applied, aiming to improve both accuracy and efficiency. The optimized hybrid feature selection combined with Random Forest classification significantly outperforms other techniques, achieving an impressive accuracy of 97% . The results demonstrate that incorporating optimized feature selection significantly enhances the predictive capabilities of the machine learning models, providing a robust approach for accurate weather forecasting. This study underscores the potential of advanced machine learning techniques in improving weather prediction, thereby contributing to better decision-making and risk management in weather-dependent activities.  \nKeywords: Optimization,Algorithms, Hybrid Feature  \n1. Introduction  \nPredicting the weather has been an important subject of research for a long time, and it has an impact on many other fields, including agriculture, aviation, disaster management, and activities that people do on a daily basis. For the sake of planning and minimizing the negative impacts that are brought about by unforeseen weather conditions, accurate weather forecasting is necessary. The numerical weather prediction (NWP) models that make use of physical equations to mimic the behavior of the atmosphere have been the primary method that meteorologists have depended on all throughout history. On the other hand, these models frequently have difficulty dealing with the intricate patterns and non-linear interactions that are present in the meteorological data, which results in limitations in the accuracy of their predictions.  \nIt has been more apparent in recent years that machine learning (ML) is a potent instrument for weather forecasting. Machine learning models have the ability to make use of previous data in order to learn and recognize patterns that are difficult to capture using conventional approaches. Although these models have demonstrated that they have the potential  \nto improve the accuracy of weather forecasts, they also confront a number of problems. The process of selecting useful characteristics from enormous volumes of meteorological data is a significant problem that might have an impact on the performance of the model. The approaches of feature selection are extremely important for determining which variables are the most useful, lowering the dimensionality of the model, and improving its efficiency. In order to meet the difficulty of accurate weather forecasting, the purpose of this study is to integrate the optimization of machine learning algorithms with hybrid feature selection approaches. For the purpose of making weather forecasting models more dependable for use in practical applications, the goal is to improve the accuracy and efficiency of these models. In order to obtain higher prediction performance, the research suggests a unique methodology that combines a number of different machine learning al","cbCailWeIv06XmAj","https://ap.wps.com/l/cbCailWeIv06XmAj","pdf",519855,1,13,"English","en",105,"# Introduction\n# Methodology\n## Data Collection and Preprocessing\n## Feature Selection","[{\"question\":\"Why is accurate weather prediction important?\",\"answer\":\"Accurate weather forecasting supports planning and reduces negative impacts from unexpected weather conditions.
