Table 7.
Left-out data prediction success of the reference-domain label derived from linear indicator regression. The first 2 columns give the gold-standard identities of reference label and task. The last 4 columns give the fraction of predictions for the 4 reference labels. Every row has been normalized such that it sums to unity. Highlighted in bold face are correct predictions. For example activation on the logical memory task was correctly identified as belonging to the episodic memory domain 70% of the time, and was misclassified as belonging to fluid reasoning 20% of the time.
