2.2 Training Dataset 语言模型的数据集已经扩大到近万亿个单词的Common Crawl数据集。但未经过滤的Common Crawl版本质量较低,因此采取了三个步骤提高数据集质量:基于多个高质量参考语料库的相似度过滤、文档级别的模糊去重和添加高质量参考语料库到训练中。最终数据集混合包括CommonCrawl数据、WebText数据集扩展版本、两个...
如果MsDataset.load方法需要一个dtype参数，那么这个参数的类型应该是dataframe.DataFrame类型，例如：datafra...
The main disadvantages are the need for a new large dataset for every task, the potential for poor generalization out-of-distribution。文章特别提到,GPT-3本身是可以用来fine-tune的,且这也是其未来的研究方向之一 为什么要把one-shot从few-shot和zero-shot中分出来,因为one-shot实际上是最贴近人的情况。
最突出的是,训练后模型所具备极强的跨领域迁移能力:迁移到十分内卷的 NLI 数据集 HANS 和 ANLI 上做测试,也都分别提升了 11% 和 9% 的准确率。 论文题目: WANLI: Worker and AI Collaboration for Natural Language Inference Dataset Creation 论文链接: 网页链接 人机如何合作? 整个方法的流程可以分成四个部分...
LAMBADA is also a demonstration of the flexibility of few-shot learning as it provides a way to address a problem that classically occurs with this dataset. Although the completion in LAMBADA is always the last word in a sentence, a standard language model has no way of knowing this detail....
短短一周不到，视觉领域接连迎来新模型“炸场”，图像识别门槛大幅降低——这场AI热潮中鲜见动静的Meta（META.US）终于出手，推出Segment Anything工具，可准确识别图像中的对象，模型和数据全部开源。据悉，Meta的项目包括模型Segment Anything Model（SAM）、数据集Segment Anything 1-Billion mask dataset（SA-1B）...
” It is a large autoregressive language model (175 billion parameters) with a decoder-only transformer network. Released in 2020 by OpenAI, it uses deep learning to understand and generate human-like responses in natural language. GPT-3 was trained on an extremely vast text dataset from ...
First, from a practical perspective, the need for a large dataset of labeled examples for every new task limits the applicability of language models. (即,fine-tune还是需要较大的数据集来进行调试,但很多任务是提供不了用来fine-tune的数据的
