Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Consistent improvements across three Q-matrix construction methods (community-provided, programmatic keyword/LLM-tag extraction, attribute grouping) confirm generalization without expert annotation. → Yagna Manasa Boyapati 2026

Yagna Manasa Boyapati, Chong Yu, Tianyu Jiang, Justin Zhan. (2026). Privacy-Preserving Heterogeneous Multi-LLM Federated Inference for Cognitive Diagnosis. arXiv preprint. https://arxiv.org/abs/2609.02947 doi:10.48550/arxiv.2609.02947
q2 · i? · design · r2
Q-matrix automatic extraction analysis in the experimental setup: ASSIST09 uses a community-provided Q-matrix, GSM8K uses keyword matching plus GPT-4o-mini-generated concept tags, and UCI derives concepts via attribute grouping and normalization.
"Consistent improvements across all three construction methods confirm that our framework generalizes well under automatically generated Q-matrices, without requiring expert annotation."
