Rubrics as Rewards (RaR): Training AI to Better Align with Human Preferences Introduction: The Challenge of Training AI for Subjective Tasks When training AI systems to handle complex tasks like medical diagnosis or scientific analysis, we face a fundamental challenge: how do we teach models to produce high-quality outputs when there’s no single “correct” answer? Traditional reinforcement learning methods rely on either: Verifiable rewards (e.g., math problems with clear solutions) Human preference rankings (e.g., scoring multiple responses) But real-world domains like healthcare and science often require balancing objective facts with subjective quality (clarity, completeness, safety). This creates three key problems: …

MedMamba Explained: How Vision Mamba Transforms Medical Image Classification

2 months ago 高效码农

MedMamba Explained: The Revolutionary Vision Mamba for Medical Image Classification The Paradigm Shift in Medical AI Since the emergence of deep learning, Convolutional Neural Networks (CNNs) and Vision Transformers (ViTs) have dominated medical image classification. Yet these architectures face fundamental limitations: CNNs struggle with long-range dependencies due to constrained receptive fields ViTs suffer from quadratic complexity (O(N²)) in self-attention mechanisms Hybrid models increase accuracy but fail to resolve computational bottlenecks The healthcare sector faces critical challenges: “Medical imaging data volume grows 35% annually (Radiology Business Journal, 2025), yet diagnostic errors still account for 10% of patient adverse events (WHO Report).” …
