The mechanism of model collapse is distribution drift caused by recursive training, a learning-level problem; whereas the spread of false claims through document copying is content-level contamination, and the two have different intervention methods.

VerifiedDistribution shift refers to the statistical distribution difference between the training environment and the deployment environment, and is the direct mechanism by which spurious correlations cause performance collapse.78% similarVerifiedBehavioral cloning simplifies the problem to supervised learning, but suffers from distribution shift, where differences between the state distributions at training time and execution time lead to error accumulation.77% similarUnverified扩散模型在生成时会倾向于模式坍缩（mode collapse），即在缺乏具体约束时输出分布集中在训练数据中出现频率最高的视觉模式上75% similarUnverifiedUnconstrained recursive self-improvement can lead to performance drift, runaway costs, and even contamination of training data through leakage.75% similarUnverifiedGenerative models cannot produce information beyond their learned parameters; every synthetic generation introduces sampling variance and truncates rare tokens, causing downstream training to accumulate statistical bias, and the recursive loop is essentially a process of information loss.75% similar
