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? When LSp was initialized with cold start (0.50 in all dimensions), all 10 executions produced consistent results with fewer iterations (average 194.6) than experiments starting from an inconsistent model. → Fabiano Dorça 2015

q2 · i? · design · r2

Simulation experiment using strategy 3 with cold-start initialization (LSp set to 0.50). All 10 executions produced consistent results, averaging 194.6 iterations and 14.6 learning problems. The article notes "inconsistencies in the student model seem to be worse than the lack of initial information about student's LS."

"Table 9 shows the number of iterations, the amount of learning problems (LP), and the resulting LSp values at the end of the simulated learning process for 10 consecutive executions of this experiment. As it can be seen, all executions produced consistent results."
