Unverified模型漂移指模型上线后由于真实世界数据分布变化导致预测性能随时间下降的现象,应对手段包括持续监控、性能告警阈值和定期或触发式再训练。78% similarUnverifiedModel drift is a core problem that AI trading systems must continuously address, referring to the phenomenon in which a model's performance degrades over time in a production environment, and it is usually divided into two categories: data drift and concept drift.76% similarVerifiedModel collapse refers to the phenomenon whereby, after an AI model is trained on data generated by a previous-generation model, the output distribution gradually deviates from the original real data distribution across multiple generations of iteration, losing information in the tail of the distribution.75% similarVerifiedModel behavior drift means that even if the code and prompts are unchanged, after the underlying model is silently updated, temperature parameters change, or context length is adjusted, the output distribution for the same input may also change.74% similarVerified模型漂移通常分为数据漂移和概念漂移两类,数据漂移指输入数据统计分布随时间变化,概念漂移指输入与输出关系本身发生变化74% similar
