Differentiable Scheduled Sampling for Credit Assignment
Open accessAbstract
We demonstrate that a continuous relaxation of the argmax operation can be used to create a differentiable approximation to greedy decoding for sequence-tosequence (seq2seq) models.By incorporating this approximation into the scheduled sampling training procedure (Bengio et al., 2015)-a well-known technique for correcting exposure bias-we introduce a new training objective that is continuous and differentiable everywhere and that can provide informative gradients near points where previous decoding decisions change their value.In addition, by using a related approximation, we demonstrate a similar approach to sampled-based training.Finally, we show that our approach outperforms cross-entropy training and scheduled sampling procedures in two sequence prediction tasks: named entity recognition and machine translation.

The PersonaChat datasets have accelerated research into persona consistency.
“The PersonaChat datasets [47, 312] have accelerated research into persona consistency [96, 128, 178, 284, 296, 307, 318].”
From Survey of Hallucination in Natural Language Generation (2023) · cites this paper as [47]
The Experimental Setup (Section 5; page unavailable) describes machine-translation and named-entity-recognition datasets, not PersonaChat. Searches for PersonaChat and persona consistency found no passage addressing whether those datasets accelerated research. (LLM, conf=0.78)

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.
