Abstract
Convex optimization techniques have become essential in predicting agricultural yields due to their ability to handle complex data relationships effectively. This meta-analysis specifically examines the use of spectral methods, a subset of convex optimization, within Uganda’s agricultural context. The primary aim is to evaluate the effectiveness and applicability of spectral methods for predicting agricultural yields in Uganda while identifying condition-number implications that could affect model performance. A comprehensive literature review was conducted, including 20 studies from peer-reviewed journals. Studies involving empirical data and methodologies related to spectral methods were selected using a systematic approach. The condition number \(\kappa = ||A||p \cdot ||A^{-1}||p\) was used to assess the sensitivity of models, where \(A\) is the matrix representing the system of equations and \(p\) denotes the norm. Spectral methods demonstrated consistent accuracy in predicting agricultural yields, with correlation coefficients ranging from 0.75 to 0.92. High condition numbers \(\kappa\) were found to significantly impact model reliability. Spectral methods are effective for predicting agricultural yields but their performance is critically dependent on the condition number of the underlying system. This underscores the importance of data quality and preprocessing. Future research should focus on improving data quality and preprocessing techniques to mitigate the effects of high condition numbers. convex optimization, spectral methods, agricultural yield prediction, condition number This meta-analysis provides a comprehensive evaluation of spectral methods in agricultural yield prediction, highlighting the critical role of condition-number implications.
