15/17 Categories
Achieved Zero Standard Deviation
A remarkable consistency, with 15 out of 17 categories showing no performance variance across multiple training runs, highlighting the system's robustness.
Unique Successes
The system's ability to achieve perfect scores on categories where symbolic approaches falter underscores the power of learning compositional rules directly from data. Specifically, the NCA surpasses all systems (including AM-Parser) on three categories:
- RC_iobj_extracted: NCA 100% vs. AM-Parser 0%. The AM algebra's apply and modify operations cannot express indirect object extraction from relative clauses.
- RC_modif_iobj: NCA 100% vs. AM-Parser 74.4%.
- PP_modif_iobj: NCA 100% vs. AM-Parser 90.4%.
This demonstrates the NCA's ability to learn and generalize specific compositional rules that hand-written algebraic systems struggle with.
Mechanism A: Novel Verb-Argument Combinations in Wh-Extraction
All failures related to active-voice object extraction and cross-clause wh-extraction (e.g., Q_dobj_ditransV, Q_iobj_ditransV, Q_long_mv, and part of Q_modified_NPs) stem from verbs appearing with reduced argument types in wh-extraction contexts. The training data lacks examples where verbs lose an argument slot due to extraction, highlighting a precise boundary in the learned compositional rules where specific verb-type transformations are not covered.
"What did Emma chase?" — 0% Accuracy (Verb type changes: (S \ NP)/ NP → S \ NP)
Source: Figure 1, Table 3, and Section 5.1 of the paper
Mechanism B: Subject-Side Modifier Attachment
All failures related to PP and RC modifiers on the subject side (PP_modif_subj and part of RC_modif_subj) arise because the training data only contains modifiers appearing on the object side (right of the verb). While the modification operation itself is known, its application in the subject-side (left of verb) context is entirely novel. This points to the learned rules being direction-sensitive and limited by the directional bias in the training distribution.
