Two new research papers propose explanations for the phenomenon of "subliminal learning" in AI models, where a student model adopts traits from a teacher model through seemingly unrelated data. The first paper suggests that subliminal learning is an artifact of Low-Rank Adaptation (LoRA) fine-tuning, dependent on specific hyperparameters and context. The second paper posits that it is a form of "steering vector distillation," where the student model learns to replicate a steering vector derived from the teacher's system prompt, explaining why it doesn't transfer between different model architectures.
