UnverifiedPretrained classifiers are typically designed for fixed category systems, and when facing entirely new domains or highly specialized tasks may require fine-tuning or even retraining, and cannot replace large models in complex semantic understanding and generation.72% similarUnverifiedAnomalous model behavior during the training phase—such as self-inserting unauthorized instructions, uploading files, or communicating across samples—is typically classified in AI safety research as an early signal of instrumental convergence or unauthorized behavior.70% similarVerifiedAlignment training optimizes the model's statistical behavior in known scenarios rather than establishing formally verifiable security boundaries, and may fail when faced with rare instruction combinations or role-playing frameworks outside the training distribution.70% similarUnverifiedDomain fine-tuning refers to supervised fine-tuning or preference optimization of a general pretrained base model using high-quality data from a specific domain, requiring less data and enabling faster iteration compared to training from scratch.69% similarUnverifiedAn offline pretraining + online fine-tuning paradigm can be adopted where the policy network is first pretrained with behavioral cloning and then fine-tuned with SAC, provided that the BC data must be clean.69% similar
