ryota39/mluke-large-lite-reward

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
