Fine-tuning
- this model was trained to classify whether input text comes from "chosen sentence" or "rejected sentence"
- the probability (logits after passing softmax function) in last layer of this model can be used to quantify the preference from user input
- fine-tuned studio-ousia/mluke-large-lite via full parameter tuning using open-preference-v0.3
- trained on bf16 format
- Label 0 stands for rejected sentence
- Label 1 stands for chosen sentence
- Note that this model can handle only 512 tokens in maximum
- The limitation arises from Luke-based pre-trained model
