Multi-Personality Generation (MPG) Datasets

Paper | Code

This repository contains datasets released as part of the Multi-Personality Generation (MPG) framework. MPG is a decoding-time paradigm that enables Large Language Models (LLMs) to simultaneously embody multiple personalization attributes without requiring extra training or multi-dimensional models.

Dataset Description

The collection includes several Direct Preference Optimization (DPO) datasets used for MBTI personality simulation and Role-Playing scenarios:

MBTI DPO Datasets

These datasets focus on specific Myers-Briggs Type Indicator dimensions:

• E / I: Extraversion vs. Introversion
• J / P: Judging vs. Perceiving
• T / F: Thinking vs. Feeling
• S / N: Sensing vs. Intuition

RolePlay DPO Datasets

• Personality: DPO data for general personality alignment.
• Profile: DPO data based on specific character profiles.
