Estadísticas

By improving the tokenization process for Japanese, we can achieve cost efficient text processing during model training as well as inference.
We train the released models on approximately 175 billion tokens of filtered data.
Our instruct model achieves an average score of 68.74, leading by almost 2 points over Youri-7B-instruction, the second best model.

How can RakutenAI-7B's success in enhancing Japanese language models impact other non-European languages

RakutenAI-7B's success in enhancing Japanese language models can have a significant impact on other non-European languages by setting a precedent for the development and improvement of large language models in these languages. The techniques and methodologies used to extend Mistral's vocabulary, improve tokenization processes, fine-tune models for specific tasks, and evaluate performance can be adapted and applied to languages that have been historically underrepresented in NLP research.
By showcasing the effectiveness of RakutenAI-7B in achieving high performance on Japanese benchmarks while maintaining competitive results on English test sets, it demonstrates the feasibility and importance of investing resources into developing advanced language models for non-European languages. This success can inspire researchers and organizations to prioritize similar initiatives for other languages, leading to more inclusive NLP advancements globally.

What potential biases or inaccuracies might arise from using large language models like RakutenAI-7B

The use of large language models like RakutenAI-7B may introduce potential biases or inaccuracies due to several factors:

Data Bias: If the training data used is not diverse or representative enough, it can lead to biased outputs that reflect societal prejudices or stereotypes present in the data.

Cultural Nuances: Language models may struggle with capturing subtle cultural nuances or context-specific meanings accurately, potentially resulting in misinterpretations or inappropriate responses.

Ethical Concerns: There is a risk of generating harmful content such as misinformation, offensive language, or biased narratives if not carefully monitored during model training and deployment.

Linguistic Limitations: Large language models might not fully capture the complexity of certain languages' grammar rules or linguistic structures, leading to errors in generation or understanding.

To mitigate these issues, continuous monitoring, ethical guidelines implementation during model training/fine-tuning phases are crucial. Additionally,
diverse datasets representation from various sources should be prioritized to reduce bias risks.

How can the development of advanced language models contribute to cross-cultural communication and understanding

The development of advanced language models like RakutenAI-7B has the potential to significantly contribute towards cross-cultural communication and understanding by:

Language Accessibility: By improving natural language processing capabilities across different languages including non-European ones; barriers related
to communication between speakers of different tongues are reduced.

Enhanced Translation Services: Advanced LLMs facilitate more accurate translation services between multiple languages which fosters better
understanding among diverse linguistic communities.

Preservation of Indigenous Languages: These sophisticated tools could aid efforts towards preserving endangered indigenous dialects through
documentation & analysis.

4 .Cultural Exchange: By enabling smoother interactions between individuals speaking different native tongues; promoting cultural exchange becomes easier fostering mutual respect & appreciation among varied cultures
Overall ,the advancement of advanced LLMs promotes inclusivity & facilitates effective intercultural dialogue essential for global harmony & cooperation
