Note Our study delves into model editing utilizing in-context learning, aiming to improve LLM responses without the need for fine-tuning or retraining. Specifically, we propose a comprehensive retrieval strategy to extract medical facts from an external knowledge base, and then we incorporate them into the query prompt for the LLM.

The dataset can be used for tasks related to automated fact-checking such as evidence retrieval, veracity prediction, and explanation generation.

Note In this work, we employ domain adaptation methods on eight LLMs, spanning six datasets and four distinct summarization tasks: radiology reports, patient questions, progress notes, and doctor-patient dialogue. Our thorough quantitative assessment reveals trade-offs between models and adaptation methods.

Note In this article, we create synthetic large-scale clinical notes using publicly available case reports extracted from biomedical literature. We then use these synthetic notes to train our specialized clinical large language model, Asclepius. Our findings convincingly demonstrate that synthetic clinical notes can serve as viable substitutes for real ones.

Note We present BioCoder, a benchmark developed to evaluate existing pre-trained models in generating bioinformatics code. In relation to function-code generation, BioCoder covers potential package dependencies, class declarations, and global variables. It incorporates functions and methods in Python and Java from GitHub and the Rosalind Project.

MedAlign is curated by 15 clinicians (7 specialities), includes clinician-written reference responses for 303 instructions, and provides 276 longitudinal EHRs for grounding instruction-response pairs.

Note We propose a localized medical benchmark called CMB, a Comprehensive Medical Benchmark in Chinese, designed and rooted entirely within the native Chinese linguistic and cultural framework. While traditional Chinese medicine is integral to this evaluation, it does not constitute its entirety.

Note This paper aims to investigate different pre-training methods, such as pre-training the biomedical LM from scratch and pre-training it in a continued fashion. We also propose and evaluate initializing weights for new tokens by distilling existing weights from the BERT model inside the context where the tokens were found.

Note This study researched the ability of large language models to extract SDoH from free text in EHRs, where they are most commonly documented, and explored the role of synthetic clinical text for improving the extraction of these scarcely documented, yet extremely valuable, clinical data.

Note This research paper focuses on the challenges posed by hallucinations in LLMs, particularly in the context of the medical domain. We propose a new benchmark and dataset, Med-HALT (Medical Domain Hallucination Test), designed specifically to evaluate and reduce hallucinations. Med-HALT includes two categories of tests reasoning and memory-based hallucination tests.

Med-PaLM M reaches performance competitive with or exceeding the state of the art on all MultiMedBench tasks, often surpassing specialist models by a wide margin.

Note We propose a framework to analyze the sections with high predictive power. Using MIMIC-III, we show that: 1) predictive power distribution is different between nursing notes and discharge notes and 2) combining different types of notes could improve performance when the context length is large.

Note In this paper, we study how LLMs can be used to scale biomedical knowledge curation. We find that while LLMs already possess decent competency in structuring biomedical text, by distillation into a task-specific student model through self-supervised learning, substantial gains can be attained over out-of-box LLMs.

Note In this work, we first find that standard open-domain and biomedical tokenizers are largely unable to segment biomedical terms into meaningful components. But surprisingly, we find that pre-training a biomedical LM using a more accurate biomedical tokenizer does not improve the entity representation quality of a language model.

Note We propose a new French public biomedical dataset on which we have continued the pre-training of CamemBERT. Thus, we introduce a first version of CamemBERT-bio, a specialized public model for the French biomedical domain that shows 2.54 points of F1 score improvement on average on different biomedical named entity recognition tasks.

Note We systematically investigate lightweight strategies to adapt large language models (LLMs) for the task of radiology report summarization (RRS). Our results on the MIMIC-III dataset consistently demonstrate best performance by maximally adapting to the task via pretraining on clinical text and parameter-efficient fine-tuning on RRS examples.

Note In this paper, we present the approach we developed to extract procedures, drugs, and diseases from oncology health records written in European Portuguese. Since there wasno annotated corpus for biomedical entity extraction in Portuguese prior to this work, we also present the strategy we followed in annotating the corpus for the development of the models.

Note In this paper, we propose an original study of PLMs in the medical domain on French language. We also release the first specialized PLMs for the biomedical field in French, called DrBERT, as well as the largest corpus of medical data under free license on which these models are trained.

Note We collected more than 700 diseases and their corresponding symptoms, recommended medications, and required medical tests, and then generated 5K doctor-patient conversations. Models finetuned on these emerge with great potential to understand patients' needs, provide informed advice, and offer valuable assistance in a variety of medical-related fields.

Note We present a comprehensive evaluation of GPT-4 on medical competency examinations and benchmark datasets. Our results show that GPT-4, without any specialized prompt crafting, exceeds the passing score on USMLE by over 20 points and outperforms earlier general-purpose models (GPT-3.5) as well as models specifically fine-tuned on medical knowledge (Med-PaLM, a tuned version of Flan-PaLM 540B).

Note The model has been trained on a large corpus of 4.7 Million German medical documents and has been shown to achieve new state-of-the-art performance on eight different medical benchmarks covering a wide range of disciplines and medical document types. In addition to evaluating the model, this paper also conducts an in-depth analysis of its capabilities.

Note Large language models have a tendency to generate factually incorrect and sometimes even toxic statements. By enabling these models to access external point-of-care tools in response to physician queries, we demonstrate significantly improved factual grounding, helpfulness, and safety in a variety of clinical scenarios.

Note In this paper, we conducted by far the largest study on biomedical VLP, using 15 million figure-caption pairs extracted from biomedical research articles in PubMed Central. BiomedCLIP established new state of the art in a wide range of standard datasets, substantially outperformed prior VLP approaches.

Note We show that relatively small specialized clinical models substantially outperform all in-context learning approaches, even when finetuned on limited annotated data. Further, we find that pretraining on clinical tokens allows for smaller, more parameter-efficient models that either match or outperform much larger language models trained on general text.

Note We present a new text-to-SQL dataset for electronic health records (EHRs). The utterances were collected from 222 hospital staff, including physicians, nurses, insurance review and health records teams, and more. Our dataset poses unique challenges: 1) generate SQL queries, 2) understand various time expressions, and 3) distinguish whether a given question is answerable.

Note We present MultiMedQA, a benchmark combining six existing open question answering datasets spanning professional medical exams, research, and consumer queries; and HealthSearchQA, a new free-response dataset of medical questions searched online. We evaluate PaLM (a 540-billion parameter LLM) and its instruction-tuned variant, Flan-PaLM, on MultiMedQA.

Note This paper examines the encoding of analogy in large-scale pretrained language models. Existing analogy datasets typically focus on a limited set of analogical relations, with a high similarity of the two domains between which the analogy holds. On the other hand, SCAN contains systematic mappings of multiple attributes and relational structures across dissimilar domains.

Note We fine-tuned a diffusion model on a corpus of publicly available chest x-rays (CXR) and their corresponding radiology (text) reports. We present evidence that the resulting model is able to create visually convincing, diverse synthetic CXR images, and that the output can be controlled by using free-form text prompts including radiology-specific language.

Note We introduce kp-biomed, the first large-scale biomedical keyphrase generation dataset with more than 5M documents collected from PubMed abstracts. We train and release several generative models and conduct a series of experiments showing that using large scale datasets improves significantly the performances for present and absent keyphrase generation.

Note Sequential task training may cause catastrophic forgetting, so we propose a continual pretraining method for the BERT-based model. Despite training only 3% of model parameters, our method could achieve better-than-SOTA performance (on chinese biomedical tasks).

Note In this paper we introduce Galactica: a large language model that can store, combine and reason about scientific knowledge. It sets a new state-of-the-art on downstream tasks such as PubMedQA and MedMCQA dev of 77.6% and 52.9%.

Note In this work, we propose a new method for learning vector representations of biomedical terms that are based on definitions and descriptions from a knowledge graph. Thanks to this grounding, our model produces more semantic concept representations than SapBERT, and which match more closely the hierarchical structure of ontologies. The model also generalizes to clinical sentences similarity (STS).
