Recently, significant efforts have been dedicated to enhancing anomaly detection methods, especially concerning high-dimensional and distributed clinical datasets. The analysis of patient information in clinical environments highlights a strong emphasis on improving diagnostic precision, tailoring treatment strategies, and maximizing resource efficiency to boost health outcomes. However, this field encounters distinct difficulties, including sporadic data gathering, variable data quality, and structural differences unique to individual patients. To overcome these obstacles, this paper introduces an innovative hybrid framework that merges stochastic and heuristic techniques for detecting anomalies in clinical patient data. This approach leverages an HPO-optimized Density-Based Spatial Clustering of Applications with Noise to group patient exercise data, thereby streamlining the detection of abnormalities. Following this, an Interquartile Range-based stochastic technique filters out untrustworthy data points, guaranteeing that healthcare practitioners and diagnostic systems are supplied with only highly relevant and precise data. The main goal of this research is to provide medical experts and scholars with a reliable instrument for handling vast, high-dimensional clinical datasets, allowing for the successful separation and elimination of deviant data observations. Additionally, an advanced regression model was constructed utilizing Automated Machine Learning (AutoML) to evaluate the effectiveness of the ensemble technique for detecting abnormal patterns. Multiple statistical error evaluation methods are employed to verify the success of this hybrid strategy in conjunction with AutoML. Empirical findings indicate that applying this cutting-edge hybrid framework to patient rehabilitation data significantly boosts AutoML performance, yielding an average improvement of 0.041 in the score, thereby outperforming conventional regression models.

The climate system is heavily influenced by aerosols through direct and indirect pathways, notably the absorption and scattering of radiant energy. Beyond climate impacts, these particles compromise atmospheric visibility and jeopardize public health. Specifically, human populations face exposure to fine particulate matter PM2.5, a major driver of respiratory and cardiovascular pathologies. Long-term modifications in PM levels are generally governed by emission shifts and meteorological patterns, whereas short-term fluctuations are predominantly dictated by immediate weather dynamics. Surface variations in PM2.5 levels are further driven by environmental variables such as temperature, wind velocity, relative humidity, and vegetative coverage.Air quality forecasting has advanced significantly through the application of machine learning. This research explores PM2.5 estimation by utilizing these environmental and meteorological metrics as spatiotemporal inputs. This study evaluates seven years (2014–2021) of in situ PM2.5 measurements gathered from five distinct monitoring stations across Singapore, establishing a baseline dataset for spatial modeling.The primary contribution of this paper is a novel predictive architecture tailored for temporal analysis, utilizing Random Forest (RF), Gradient Boosting (GB) regression, and the Tree-based Pipeline Optimization Tool (TP) Auto ML framework, which optimizes via a meta-heuristic genetic algorithm. The TP model demonstrated strong predictive capabilities, achieving a peak Global Performance Index (GPI) of 7.4 in August 2016 and a minimum value of −0.6 in June 2019. These metrics highlight the robust nature of the TP framework; its negative values remained superior to competing models, indicating less pessimistic errors. Finally, the underlying logic of these machine learning systems is clarified using eXplainable Artificial Intelligence (XAI) methods, which validate the integrity of feature importance and offer deeper insights into the cyclical variations of PM2.5 concentrations.
