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? The LSTM-based evidence model achieved higher predictive accuracy (64.82%) than random forest (50.43%), SVM (41.17%), and the majority-class baseline (35.71%) on held-out test data. → Akram 2018

q2 · i? · design · r2

Computational evaluation on behavior trace data from 168 middle school students who completed both tests and all 11 binary tasks, with training/test split and 100 training runs averaged. The LSTM achieved "an average accuracy of 64.82%" versus RF 50.43%, SVM 41.17%, and baseline 35.71% (Table 2).

"The results of applying this LSTM on the held -out test set achieve an average accuracy of 64.82%, an average precision of 63.88%, an average recall of 65.14%, and an F1-score of 63.68%."
