UnverifiedData drift or concept drift refers to the distribution of real-world data changing over time, which causes ML model accuracy to decline—this is a significant difference between MLOps and traditional software operations.77% similarUnverifiedUser-perceived model "deterioration" is often the cumulative result of multiple factors including silent updates, tightened safety alignment, dynamic downgrading of inference resources, and user expectation drift, and does not always indicate a genuine regression in model capability.69% similarUnverified用新数据更新模型时可能破坏原有能力，即灾难性遗忘，工业界通过失败案例库、数据增强与混合回放技术来整合新数据68% similarUnverified数据脱敏操作本质上是在降低数据的信息熵，可能削减模型用于精准判断的特征维度67% similar
