This paper presents a novel approach to hand gesture recognition based on machine learning techniques applied to data collected from wearable sensors. The proposed system aims to accurately identify intuitive hand gestures to facilitate the development of contactless user interfaces. To achieve robust and reliable recognition performance, various feature extraction methods were systematically employed, and an ensemble learning strategy was developed using Support Vector Machines (SVM), Random Forests (RF), Gradient Boosting (GB), and a Voting Classifier (VC). The gesture dataset utilized in this study consists of over 4,000 samples collected from multiple individuals, capturing diverse gesture classes and conditions. Rigorous experimental evaluation demonstrates that the proposed ensemble approach attains superior accuracy and robustness compared to traditional single-model methods. This research contributes valuable methodological insights and provides an accessible, scalable framework that enhances the practical applicability of sensor-based gesture recognition systems in diverse real-world applications.

The Flexible Job Shop Scheduling Problem (FJSP) is a critical combinatorial optimization problem in modern manufacturing systems, characterized by multiple constraints, dynamic requirements, and NP-hard complexity. This paper presents an improved Ant Colony Optimization (ACO) algorithm specifically designed to address the FJSP by minimizing makespan. The proposed algorithm incorporates enhanced pheromone update mechanisms, dual-level solution encoding for operation sequencing and machine assignment, and adaptive search strategies. Experimental results on a benchmark problem with 4 jobs, 3 processes per job, and 6 machines demonstrate that the improved ACO achieves superior performance compared to traditional metaheuristics, reducing makespan by approximately 8.7% compared to genetic algorithms. The convergence analysis shows stable optimization behavior within 40 iterations, validating the effectiveness and practical applicability of the proposed approach.

The core objective of this research is to construct a machine learning-based air quality prediction model. This model aims to forecast the Air Quality Index (AQI) for the next 72 hours and classify its corresponding levels (e.g., Good, Moderate, Polluted), providing a robust scientific basis for environmental protection departments and related decision-making. For feature selection, we analyzed multiple key factors affecting air quality. While meteorological data, spatiotemporal features, and external pollution sources are important, this study focuses on the historical concentrations of six critical pollutants (PM2.5, PM10, SO2, NO2, CO, and O3) as model inputs to establish a baseline model, acknowledging the need for incorporating broader influencing factors in future work. In the model construction phase, we performed extensive preprocessing on the collected historical air quality data, including standardization and normalization, to extract effective information. We then employed and compared several advanced machine learning algorithms, selecting the optimal combination to build the final prediction model. The experiments were conducted using the Python language. By continuously optimizing model parameters and feature combinations, we achieved predictions for both the numerical AQI values and their corresponding quality levels for the subsequent 72 hours. Experimental results demonstrate that the constructed model possesses high prediction accuracy and stability for the predominant “Excellent” and “Good” categories. However, the lack of severe pollution events in the dataset limits the evaluation of its predictive capability for pollution peak events.

The Traveling Salesman Problem (TSP) is a classic NP-hard combinatorial optimization problem where traditional intelligent algorithms often suffer from slow convergence and premature convergence to local optima. This paper proposes a novel hybrid optimization framework (HGA-PSO-ACO) that integrates the global exploration capability of the Genetic Algorithm (GA), the rapid convergence characteristics of Particle Swarm Optimization (PSO), and the positive feedback mechanism of Ant Colony Optimization (ACO) through a three-stage adaptive coordination model. The key design challenge is to determine when each component should dominate the search and how information should be transferred across stages without causing premature homogenization of the population. To address this issue, the algorithm employs fitness variance (FVD) for real-time population state monitoring and implements dynamic algorithm switching strategies. Experimental validation on a 40-city TSP benchmark demonstrates that the hybrid algorithm achieves a 40% faster convergence speed, a 2.1% lower relative error, and a 58.3% reduction in run-to-run standard deviation compared to individual algorithms, indicating improved solution stability together with favorable parameter sensitivity control.
