Cost-Aware and Self-Validating Multi-Agent Engineering of Computer-Vision Pipelines: An Optimization-Based Framework with Applications to Remote-Sensing Image Analysis

Remote-sensing image analysis increasingly requires workflows that combine heterogeneous sensors, geospatial preprocessing, deep-learning models, uncertainty estimation, and domain-specific quality control. Conventional computer-vision pipelines are commonly designed manually, making them expensive to develop, difficul...

Crop Yield Estimation with MODIS Derived Normalized Difference Vegetation Index and Comparative Study on Crop Yield Prediction Among Linear Regression, Random Forest and Gradient Boosting as Well as CatBoost

This paper presents the design, development, and evaluation of a machine-learning system built to forecast agricultural crop yields across Indian states between 2000 and 2026, together with a complementary, national-scale verification of predicted crop yield using a MODIS-derived NDVI time series (MOD13A3.061 Vegetatio...
