UnverifiedThe technical core of the method combines a TopK sparse autoencoder with two mechanisms: route-exclusive supervision and cross-factor adversarial training.72% similarUnverifiedThe solution proposed by the author is to insert a locally controlled proxy layer into the call chain, including two core practices: model fingerprint detection and prompt minimization and desensitization.66% similarUnverifiedAnthropic、DeepMind等机构近年来大量采用激活补丁类方法研究大模型内部电路，形成了因果追踪方法论65% similarUnverifiedThe paper's authors suggest integrating contrastive direction probing into DevSecOps artifact verification pipelines, comparing the directional deviation of intermediate-layer activations between the base model and the fine-tuned model under probe prompts, rather than only looking at output behavior.64% similarUnverifiedThe current mainstream "mechanistic interpretability" uses probes, sparse autoencoders, circuit analysis and other means to locate the neurons or subnetworks corresponding to specific capabilities.64% similar
