  "title": "DCM-SAM: Defect-Conditioned Mixture of LoRA Experts for NPU-Deployed AM Defect Segmentation",
  "summary": "The method replaces full fine-tuning or prompt-based use of a large Segment Anything model with a frozen ViT-B backbone carrying per-class Conv-LoRA expert banks and separate mask decoders, trained on synthetic data with only 4.4% of parameters updated. Costs include one training pass per defect class, added per-expert storage and routing complexity, and deployment engineering: activation memory, not weights, blocks ViT-H/L on the NPU, and the adapted ViT-B encoder requires a numerically identical attention rewrite to fit. It can fail when real data diverges from the synthetic distribution, when the target NPU compiler cannot allocate the adapted encoder, and when new defect classes demand additional expert banks rather than a single general model.",
  "rationale": "LoRA adaptation of a frozen SAM backbone fits a single 24 GB GPU and the synthetic-to-real transfer result is directly relevant to scarce-label inspection tasks, but the per-class expert design and NPU-specific attention rewrite require workload- and hardware-specific validation before production adoption.",
