Training Data for Large Language Model
It provides a comprehensive overview for researchers and practitioners in AI, but it is incremental as it synthesizes existing knowledge without introducing new methods or data.
The paper summarizes the current state of pretraining and fine-tuning data for large-scale language models, covering aspects like data scale, collection methods, and open-source datasets, based on the recognition that rich, high-quality datasets are critical for building smarter models, as exemplified by ChatGPT's performance improvements.
In 2022, with the release of ChatGPT, large-scale language models gained widespread attention. ChatGPT not only surpassed previous models in terms of parameters and the scale of its pretraining corpus but also achieved revolutionary performance improvements through fine-tuning on a vast amount of high-quality, human-annotated data. This progress has led enterprises and research institutions to recognize that building smarter and more powerful models relies on rich and high-quality datasets. Consequently, the construction and optimization of datasets have become a critical focus in the field of artificial intelligence. This paper summarizes the current state of pretraining and fine-tuning data for training large-scale language models, covering aspects such as data scale, collection methods, data types and characteristics, processing workflows, and provides an overview of available open-source datasets.
