Introducing LINE’s Open-Source Japanese Language Models
In November 2020, LINE began a transformative journey to create a powerful language model specifically for the Japanese language. As a significant milestone in this journey, LINE’s Massive LM development unit has released their Japanese language models, “Japanese-large-lm,” as open-source software (OSS). This release is poised to have a significant impact on both the research community and businesses looking to leverage cutting-edge language models.
The models come in two variants: the 3.6 billion (3.6B) parameter model and the 1.7 billion (1.7B) parameter model, known as the 3.6B model and 1.7B model. These models are accessible through the HuggingFace Hub and seamlessly integrate into various projects using the popular transformers library.
LINE’s approach to model construction is carefully detailed, providing insights into their methodology and contributing to the advancement of the field. By licensing these models under the Apache License 2.0, LINE ensures that researchers and commercial entities can utilize their capabilities for diverse applications.
The key to developing a high-performing language model lies in using an extensive and high-quality training dataset. LINE utilized its proprietary Japanese web corpus, a repository of diverse textual data. To overcome the challenge of noise in web-derived content, LINE employed meticulous filtering processes with the help of the HojiChar OSS library. These processes distilled a large-scale, high-quality dataset to ensure the models’ robustness.
Efficiency in model training was prioritized, and LINE implemented innovative techniques like 3D Parallelism and Activation Checkpointing. These advancements allowed for the assimilation of voluminous data, pushing the boundaries of computational capability. Impressively, the 1.7B model was developed using just 4000 GPU hours on an A100 80GB GPU.
LINE’s dedication to crafting exceptional pre-trained models for the Japanese language is evident in the development trajectory of this language model. Their commitment to integrating insights and lessons from their experience with large-scale language models shines through.
To assess the models’ efficacy, LINE analyzed perplexity scores (PPL) and accuracy rates for question-answering and reading comprehension tasks. The results were promising, with LINE’s models showcasing competitive performance across various tasks, rivaling established models in the field. LINE also shared invaluable tips for effective large-scale language model training.
In conclusion, LINE’s release of the 1.7B and 3.6B Japanese language models marks a significant stride in natural language processing. As LINE continues to make advancements, the global community eagerly anticipates the enduring impact of their ongoing contributions.
