From Word Embeddings to Pre-Trained Language Models: A State-of-the-Art Walkthrough

Open access

Abstract

With the recent advances in deep learning, different approaches to improving pre-trained language models (PLMs) have been proposed. PLMs have advanced state-of-the-art (SOTA) performance on various natural language processing (NLP) tasks such as machine translation, text classification, question answering, text summarization, information retrieval, recommendation systems, named entity recognition, etc. In this paper, we provide a comprehensive review of prior embedding models as well as current breakthroughs in the field of PLMs. Then, we analyse and contrast the various models and provide an analysis of the way they have been built (number of parameters, compression techniques, etc.). Finally, we discuss the major issues and future directions for each of the main points.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CoVe encounters the OOV issue by assigning zeros to represent unknown words.

    “By assigning zeros to represent unknown words, this approach also encounters the OOV issue (McCann et al. 2017; Mars 2022), as depicted in Fig. 4.”

    From Large language models (LLMs): survey, technical frameworks, and future challenges (2024) · cites this paper as Mars 2022

    The Max-Margin Loss (MML) section describes CoVe’s contextual embeddings but does not say it represents unknown words with zeros or encounters an OOV issue. A nearby OOV discussion concerns fastText, not CoVe. Searches for CoVe with unknown words, zero vectors, and OOV found no passage supporting the attributed claim. (LLM, conf=0.75)

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.
