For LIA2S4PHC framework development, we have applied two LoRa SX1278 (transmitter and receiver end), two ESP 32 microcontrollers, six tin-oxide-based cross-selective gas sensors, one particulate matter sensor, one temperature and humidity sensor, and one GPS module. LoRa is used to transmit airborne signatures from the experimental zone to the central monitoring station (CMS) for further processing. On performing the LIA2S4PHC range test, it was found that up to 745 m information was obtained correctly in open space. The messages started getting missed after that, and at about 765 m there was no reception. The captured airborne signatures were pre-processed using the standardized principal component analysis (SPCA) for 3D scattering. Naïve Bayes (NB), support vector machine (SVM), multi-layer perceptron (MLP), Categorical Boosting (CatBoost), and tabular network (TabNet) models were applied to classify the types of harmful gases/odors/airborne signatures with classification average accuracies such as 82%, 84%, 91%, 91%, and 92%, respectively.

However, the inherent nonlinearity and noise in wind power data—driven by multiple influencing factors such as wind speed and temperature—pose significant challenges for accurate prediction. To address this, we propose a hybrid forecasting framework that integrates secondary decomposition with multiple predictive algorithms. First, Singular Spectrum Analysis (SSA) is employed to extract the primary trend and periodic components, followed by Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN) for further signal decomposition. Fuzzy entropy is then used to reconstruct the components into high-frequency, mid-frequency, and trend sub-series, effectively denoising the data and capturing multiscale features. For forecasting, an IDF-Informer model—incorporating Intra-layer Directional Fusion and optimized via a multi-strategy Improved Sand Cat Swarm Optimization (ISCSO)—is used for the high- and mid-frequency components, while the trend component is predicted using a Random Vector Functional Link Network without Direct(RVFLwoDL).

However, it fails to fully leverage both high-resolution samples and their feature maps to extract more privileged information at the distillation point. To this end, this paper proposes a Multi-source Feature Map Distillation (MsFMD) method to further improve the performance of low-resolution object recognition in practical applications such as intelligent video surveillance. We design a feature decoder with a channel attention mechanism to better leverage the privileged information from the teacher model and employ multi-level decoder modules to process deep features, achieving multi-level feature map distillation. Additionally, this paper introduces a joint data augmentation method, effectively enhancing the student model’s adaptability and robustness across samples with varying resolutions.
