Abstract

While state-of-the-art neural network models continue to achieve lower perplexity scores on language modeling benchmarks, it remains unknown whether optimizing for broad-coverage predictive performance leads to human-like syntactic knowledge.Furthermore, existing work has not provided a clear picture about the model properties required to produce proper syntactic generalizations.We present a systematic evaluation of the syntactic knowledge of neural language models, testing 20 combinations of model types and data sizes on a set of 34 English-language syntactic test suites.We find substantial differences in syntactic generalization performance by model architecture, with sequential models underperforming other architectures.Factorially manipulating model architecture and training dataset size (1M-40M words), we find that variability in syntactic generalization performance is substantially greater by architecture than by dataset size for the corpora tested in our experiments.Our results also reveal a dissociation between perplexity and syntactic generalization performance.

  • GPT-3 is evaluated as the model with outperforming BLEU score among four state-of-art text generation methods (RNN, GAN, GPT, and CTRL) and the best syntactic generalization score among trained and off-the-shelf models.

    “It is evaluated as the model with outperforming bilingual evaluation understudy (BLEU) score among four state-of-art text generation methods (RNN, GAN, GPT, and CTRL) [66] and the best syntactic generalization score among trained (LSTM, ON-LSTM, Transformer, n-gram) and ofthe-shelf (GPT, JRNN, Transformer-XL) models [46].”

    From Synthetic Lies: Understanding AI-Generated Misinformation and Evaluating Algorithmic and Human Solutions (2023) · cites this paper as [46]

    The cited paper’s Results (§4) identify GPT-2-XL, not GPT-3, as the best-performing model on syntactic generalization score. Its Off-the-shelf models section (§3.4) lists GPT-2 and GPT-2-XL among the models tested. The BLEU-score comparison is attached to a different citation in the citing sentence and is not assessed here. (LLM, conf=0.90)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
