Deploying Multi-Turn RL Infrastructure for Amazon Nova on Amazon SageMaker HyperPod
TutoSartup excerpt from this article:
When you build enterprise agents that execute multi-step workflows, you face a fundamental training challenge... Supervised fine-tuning (SFT), retrieval-augmented generation (RAG), and continued pre-training are complementary techniques, but they typically do not teach these sequential decision-making capabilities on their own... Amazon SageMaker AI also offers multi-turn RL as a fully managed, s...

Automatically redact PII in images with Amazon Nova
TutoSartup excerpt from this article:
PII redaction in real-world image datasets is particularly challenging... Unlike structured text, PII in images can appear in unexpected places and forms: a partial face captured at the edge of a frame, a face reflected on the polished surface of a car, a partially visible street sign that, combined with other visual cues, becomes identifiable, or a document lying on a desk in a wide-angle photo...
