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? Comparisons to a feature-based linear regression baseline only partly revealed advantages for the DNN target models, and the T-tests were not significant. → Lohmann 2025

q2 · i? · design · r2

Baseline comparisons in the main experiments used ridge regression with the 220-feature set; the feature DNN even fell short in four of six MEWS traits (average ΔQWK −0.02), while ASAP advantages were small (0.02 and 0.01).

"comparisons to the feature-based linear regression baseline only partly revealed advantages for the target models, and T-tests were not significant ( pfeatures = 0.818 , pembeddings = 0.465 )."
