PwC-Embedding-expr
We trained the PwC-Embedding-expr model on top of the multilingual-e5-large-instruct embedding model.
To enhance performance in Korean, we applied our curated augmentation to STS datasets and fine-tuned the E5 model using a carefully balanced ratio across datasets.
⚠️ This is an experimental model and is under continuous development.
