BloombergGPT
https://www.bloomberg.com/company/press/bloomberggpt-50-billion-parameter-llm-tuned-finance/
Bloomberg trained an LLM from scratch on AWS (64 × 8 A100 40GB for 53 days). They constructed a 363 billion token dataset based on Bloomberg’s extensive data sources, perhaps the largest domain-specific dataset yet, augmented with 345 billion tokens from general-purpose datasets.
BloombergGPT outperforms similarly-sized open models on financial NLP tasks by significant margins — without sacrificing performance on general LLM benchmarks

Few-Shot Learning in NLP
Two recent papers on few-shot learning in NLP caught my eye: 1st on retrieval by Google Research and 2nd on classification by Intel and HuggingFace
Dai, Zhuyun, et al. “Promptagator: Few-shot Dense Retrieval From 8 Examples.” arXiv preprint arXiv:2209.11755 (2022).
we suggest to work on Few-shot Dense Retrieval, a setting where each task comes with a short description and a few examples. To amplify the power of a few examples, we propose Prompt-base Query Generation for Retriever (Promptagator), which leverages large language models (LLM) as a few-shot query generator, and creates task-specific retrievers based on the generated data.
Tunstall, Lewis, et al. “Efficient Few-Shot Learning Without Prompts.” arXiv preprint arXiv:2209.11055 (2022).
we propose SetFit (Sentence Transformer Fine-tuning), an efficient and prompt-free framework for few-shot fine-tuning of Sentence Transformers (ST). SetFit works by first fine-tuning a pretrained ST on a small number of text pairs, in a contrastive Siamese manner.
(Very) Large Language Models in 2022
I feel quite amazed by the few-shot or even zero-shot learning capabilities of some recent (very) large language models. Here are three papers I read recently and would like to recommend:
– 540B PaLM by Google: https://arxiv.org/abs/2204.02311
– 11B Atlas by Meta: https://arxiv.org/abs/2208.03299
– 20B AlexaTM by Amazon: https://arxiv.org/abs/2208.01448

Version mismatch in embedding-based retrieval
Version mismatch in embedding-based retrieval is challenging, esp. on the infra side.

NER with small strongly labeled and large weakly labeled data
Small strongly labeled and large weakly labeled data is a very common situation we may run into in NLP or ASR modeling. Amazon search team used this three-stage NEEDLE Framework to take advantage of large weakly labeled data to improve NER. Their noise-aware loss function is interesting and worth taking a deep dive into.
