A critical area is weather prediction, which has a direct application in agriculture, transport, disaster response, and energy control. The traditional techniques for weather forecasting sometimes fail to produce reliable results and are hardly scalable. This paper introduces an OSP-DNN fluid dynamics-based methodology for meteorological purposes, such as reliable and efficient weather prediction. Compared with asymmetric or indefinite matrices that can introduce adverse im pacts on neural networks, the proposed model takes advantage of the properties of SPD matrices to improve the learning efficiency and robustness of neural net works. The two investigated models include the baseline Positive Definite Neural Network (PDNN) and the optimized version (OSP-DNN). Compared to other methods, their efficiency is assessed in terms of accuracy, computational speed, and robustness to different data sets. The approach includes parametric simula tion of climate patterns, learning over mock data sets, and evaluation steps. The solutions presented to prove that the OSP-DNN is more precise than the tradi tional approach and improves the baseline PDNN by up to 25% with favorable time complexity. Experimental and numerical models are compared, and the consequence of the real-world small-scale models for practical problems is de scribed. This work lays the ground norms for the integration of mathematical structures within machine learning frameworks in the gap between theory and practice.
