Prediction performance for TinyLSTM on Filler-Gap Dependencies (hierarchy)

Description
AccuracyPredictionDescription
91.67% (575,what_subjgap/6,filler) < (576,that_subjgap/6,filler) We expect the “filler” region to be lower surprisal in the what_gap condition than in the that_gap condition, because gaps must be licensed by upstream wh words (such as “what”).
41.67% (573,what_nogap/6,filler) > (572,that_nogap/6,filler) We expect the “filler” to be less surprising in the that_no-gap condition than in the what_no-gap condition, because an upstream wh-word should set up an expectation for a gap.
