Intelligent hyperlocal weather forecasting system based on small-sized neural network models and local data
Accurate short-term weather forecasting remains a key challenge in meteorology, particularly at the local scale where global numerical models (e.g., WRF, GFS) often fail to capture fine-grained atmospheric dynamics. This study presents a neural network–based approach designed to improve the accuracy of short-term (up to 24 hours) weather forecasts by integrating local meteorological observations with outputs from large-scale models. The proposed architecture follows an encoder–decoder structure with multi-head attention, enabling the model to learn spatiotemporal dependencies and correct s
Сreating image datasets for training neural networks of сonveyor video analytics
The paper presents a technology for generating synthetic data for training computer vision neural networks used in industrial quality control tasks. A method of image generation using the Unity game engine is proposed, which makes it possible to create photorealistic scenes of the production process, simulate the movement of objects on the conveyor and form various types of laminate defects. Algorithms for changing textures, lighting, camera angles, and defect characteristics are implemented, which ensures high diversity and realism of the training sample. To test the effectiveness of the appr
An integrated approach to object detector compression and evaluation using the YOLO example
The article presents a software module for complex optimization of object detection models using the YOLO11 architecture as an example. The developed system implements a full cycle of working with the model — training, pruning, fine-tuning, quantization and subsequent comparative analysis. During the experiments, two modifications of YOLO11m and YOLO11n were evaluated using the CompDetect and Safety Helmet Detection datasets, which differ in complexity and image structure. The results showed that the use of the proposed module reduces computational costs while maintaining a high level of det
Generalized metrics for evaluating recommendation algorithms as a criterion for optimizing hyperparameters
This paper considers an approach to optimizing hyperparameters of recommendation algorithms using an integral assessment that combines several metrics into four key subindexes: accuracy, ranking, diversity, and resource intensity. This method allows for a more balanced tuning of models, ensuring improved quality of recommendations without loss in individual characteristics. Unlike adjusting for one metric, which can worsen the rest of the parameters, the proposed approach takes into account the mutual dependencies between the metrics. It is shown that different algorithms react differently to
Formation of artificial data from inert materials for training computer vision neural networks using the example of crushed stone production
The article presents a research approach to the formation of synthetic data for training neural networks of computer vision systems using the technological process of crushed stone production as an example. The main attention is paid to the problem of scarcity and heterogeneity of real images used in the training of industrial computer vision models. In order to overcome these limitations, a method for generating photorealistic images based on the Unity game engine and the Unity Perception toolkit is proposed. An algorithm for generating pseudorandom objects based on the deformation of the ico
