Training an AI to communicate in a way that’s more helpful, accurate, and safe
In recent years, large language models (LLMs) have made significant strides in various tasks such as question answering, summarization, and dialogue. The ability to engage in dialogue is particularly intriguing because it involves flexible and interactive communication. However, dialogue agents powered by LLMs have been known to express inaccurate or fabricated information, use discriminatory language, or even promote unsafe behavior.
To address these concerns and create safer dialogue agents, researchers are exploring new methods for training dialogue agents that prioritize safety and accuracy. In their latest paper, the team introduces Sparrow – a dialogue agent designed to engage in conversations, answer questions, and conduct internet searches using Google to provide evidence-based responses. Sparrow represents an advancement in the journey toward safer and more useful artificial general intelligence (AGI) by emphasizing helpfulness, correctness, and harmlessness.
How Sparrow works
Training a conversational AI presents unique challenges, as defining successful dialogue is complex. To tackle this, researchers turned to reinforcement learning (RL) based on human feedback, using participants’ preferred responses to train the model on the usefulness of its answers. By gathering data through showing participants various model answers to the same question and soliciting their preferences, the team was able to discern when an answer should be supported by evidence.
In addition to emphasizing usefulness, the team imposed rules to ensure the safety of Sparrow’s behavior. These rules, such as refraining from making threatening statements or hateful comments, were informed by existing work on language harms and consultations with experts. The introduction of rules, along with training participants to converse naturally or adversarially with Sparrow, resulted in improved rule-following but acknowledged that additional input is necessary for a more comprehensive set of rules.
Towards better AI and better judgments
To evaluate the accuracy and supportiveness of Sparrow’s answers, participants found that Sparrow provided plausible answers supported by evidence 78% of the time when asked a factual question, signifying considerable progress over baseline models. However, the researchers acknowledged that Sparrow still had room for improvement, with instances of factual errors and off-topic answers.
Looking ahead, the team emphasizes the need to collaborate with experts, policymakers, and ethicists to develop a more robust set of rules for dialogue agents, acknowledging that obtaining input from diverse users and affected groups is critical for the refinement of rules and norms. Additionally, the researchers highlighted the importance of aligning dialogue agents with human values, emphasizing the significance of agents declining to answer certain questions and the need to extend their research to other languages and cultural contexts.
A path to better judgments of AI behavior
In sum, Sparrow represents a leap forward in understanding how to train dialogue agents to be both useful and safer. However, the researchers underscore the necessity of aligning dialogue agents with human values, ensuring that their behavior not only avoids harm but aligns with effective and beneficial communication.
Looking to the future, the team hopes that ongoing conversations between humans and machines will lead to improved judgments of AI behavior, ultimately facilitating the alignment and improvement of systems that may be too complex to comprehend without the assistance of machine learning.
Conclusion
The research underscores the importance of training AI to communicate in a way that prioritizes helpfulness, correctness, and harmlessness. Sparrow’s development represents a significant step forward in the pursuit of safer AI, acknowledging the need for ongoing collaboration and refinement to ensure that dialogue agents align with human values and cultural contexts.
