Personas are also used to generate diverse synthetic data and elicit unique outputs from the model.
In reinforcement learning from human feedback, creating a reward model to train language models can lead to perverse optimizations where the model finds ways to manipulate the reward model rather than understanding human desires. To prevent this, researchers introduce the concept of an anchor or callback labeler divergence score to ensure the model stays close to its original behavior. This technique, called multi-run fusion, trains multiple copies of the language model independently against the reward model and the callback labeler, then merges their weights to create a more aligned model. This process is repeated to gradually improve the model's alignment. Another interesting paper discusses the challenge of generating synthetic data for AI models. The solution proposed is the use of personas, which are descriptions of different types of people. By tailoring prompts to these personas, the model provides unique outputs, eliciting a broader range of information from the model. The paper by Tencent AI Lab Seattle introduces a text-to-persona strategy to generate personas and a persona-to-persona strategy to derive additional personas based on interpersonal relationships. They have released over 200,000 personas and are open to releasing more, acknowledging the potential risks and concerns.
