Infinity-Preference
The focus of human preferences varies from task to task. Therefore, Infinity-Preference attempts to adjust preference attribute weights on each task based on (Infinity Instruct's)[https://huggingface.co/datasets/BAAI/Infinity-Instruct] capability labelling system. This version contains 59438 evenly sampled instructions from Infinity-Instruct's instruction set for each task type. Each instruction is accompanied by a preference pair sampled from Gemma-2-9B-IT.

Dataset Description
This is a Direct Preference Optimization (DPO) dataset designed to train language models to produce high-quality, context-aware responses when given user demographic information (persona).

GSM8K Iteration 1
Overview
This dataset is derived from the GSM8K training set questions. The process to create this dataset involved the following steps:
Initial Prompting: Each question from the GSM8K train set was initially answered by the Mistral model.
Filtering Incorrect Answers: Incorrect responses were filtered out.
Refinement: The model was prompted to refine its answers based on the incorrect responses.
Final Filtering: The refined responses were filtered again… See the full description on the dataset page: https://huggingface.co/datasets/August4293/gsm8k_preference_dataset_it_1.
