Introduction

This is a result of LLM2024 competition on UTokyo seminor.

• Dashboard score is 3.05

Including

• Fine-tuned Model
• README (this file)

Dataset

This model used the following dataset for fine tuning only.

Language	Dataset	License	Description
Japanese	ichikara-instruction-003-001-1.json	CC-BY-NC-SA	ichikara-instruction: LLMのための日本語インストラクションデータ

How to build this model

You can use Google colab in T4 runtime:

• It takes about 18 - 40 minutes
• If possible, strongly recommend you followings:
  • Use {model|data}.to('cuda') to shorten your learning duration
  • Use A100
• I used following code (removed):
  • Evalution on Learning to avoid over-learning
  • WandB to check parameter tuning
