Abstract

fetched live from OpenAlex

The logical explanation about the spatial organization and usage of local capabilities and application of basic strategic to obviate complications is required to identifying the environment and using modern techniques to achieve this goal. Climatic regionalization or knowing different climatic regions is necessary for planning and territory sustainable development. The aim of this research is to recognize the most influential climatic elements affecting the climate of Qazvin province, and the spatial separation of climatic regions by using multivariate statistical methods. To this end, mean data of 28 climatic elements in 20 internal synoptic climatology stations both inside and adjacent to the borders of Qazvin Province were gathered and exploited. The correlated matrices of standardized data of the 28 climatic elements were analyzed using factor analysis in 623 spatial pixels, in the province of Qazvin. This analysis on the correlated matrices of standardized data showed that with 9 principal components, more than 99.21% of the spatial changes of the regional elements in the province can be described. At the same time, the temperature elements, humidity elements and rainfalls have in the central and eastern and north and south evident in the province. Applying agglomerative hierarchical cluster analysis in

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
