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? Across participant-based cross-validation, the modality-aware reference model achieves an MAE of 0.80, 83.18% within-1 accuracy, 70.96% binary accuracy, and 62.90% binary Macro-F1, outperforming the listed baseline families. → Zikang Leng 2026

q2 · i? · design · r2
Benchmark evaluation of the EduGage dataset under a participant-grouped four-fold cross-validation protocol (Table 4). The modality-aware model achieved the lowest MAE of 0.80, versus an MAE of 1.05 for the task-informed Peer Window Mean baseline. The authors note the remaining error demonstrates the difficulty of the task.
