AWS Lambda enhances Amazon Nova model customization

Amazon Web Services (AWS) is detailing how its Lambda serverless compute service can be used to build effective reward functions for customizing the Amazon Nova model. The blog post highlights the scalability and cost-efficiency of using Lambda for this purpose. It guides users on selecting between Reinforcement Learning via Verifiable Rewards (RLVR) for objective tasks and Reinforcement Learning via AI Feedback (RLAIF) for subjective assessments. The content also covers designing multi-dimensional reward systems to prevent reward hacking and optimizing Lambda functions for training scale, with monitoring facilitated by Amazon CloudWatch.
