Structured Multi-Kernel Heteroscedastic Gaussian Process for Crop Straw-to-Grain Ratio Prediction and Uncertainty Quantification

Crop straw-to-grain ratio (SGR) estimation underpins regional straw resource assessment, yet national inventories rely on fixed coefficients that ignore structured variation across variety, environment, and phenotype. We introduce a Structured Multi-Kernel Heteroscedastic Gaussia...

Online Detection and Grading of Tomato External Quality Based on Machine Vision

Abstract Tomato shape and mass are key indicators for external quality evaluation, while manual inspection is inefficient and subjective. This study proposes an online method for tomato external quality detection and grading based on machine vision. Images of 1,000 tomato samples...

Research on an Innovation Opportunity Identification Method Based on Link Prediction in Heterogeneous Networks

A large number of potential knowledge associations in scientific and technological innovation activities have not yet become explicit. How to identify potential valuable innovation opportunity clues from complex knowledge structures has therefore become an important issue in inte...

Beyond the Private Sphere: Women's Community Participation and Household Diet Quality in Rural China

ABSTRACT Improving diet quality remains a key challenge in post‐poverty rural China. This study examines how women's community participation, a form of public‐sphere agency, relates to household diet quality. We introduce a Food‐Weighted Dietary Diversity Index (FWDDI) that captu...
