摘要：
为解决企业级ETL数据流中频发的异常问题，提出了一种基于深度自编码器的异常检测方法。研究首先分析了ETL流程中的多种异常类型，包括延迟、缺失值、重复加载和突发异常变化，并应用数据标准化和特征建模以确保输入的稳定性和可用性。在方法设计中，编码器-解码器结构将高维输入压缩为潜在表示并进行重构，同时利用重构误差来衡量异常水平。在潜在空间中引入正则化约束以增强特征稀疏性和分布学习，从而提高在复杂数据流中的鲁棒性。在不同超参数设置、环境变化和数据特征下的系统分析表明，所提方法在AUC、ACC、Precision和Recall上取得了优越的性能。结果表明，基于深度自编码器的检测机制能有效捕获企业级ETL数据流中的潜在分布模式，准确识别各种异常，为企业数据处理和智能分析提供可靠支持。
英文摘要：
An anomaly detection method based on deep autoencoders is proposed to address anomalies that often occur in enterprise-level ETL data streams. The study first analyzes multiple types of anomalies in ETL processes, including delays, missing values, duplicate loading, and sudden abnormal changes, and applies data standardization and feature modeling to ensure stable and usable inputs. In the method design, the encoder-decoder structure compresses high-dimensional inputs into latent representations and reconstructs them, while reconstruction error is used to measure anomaly levels. Regularization constraints are introduced in the latent space to enhance feature sparsity and distribution learning, thereby improving robustness in complex data streams. Systematic analyses under different hyperparameter settings, environmental changes, and data characteristics show that the proposed method achieves superior performance in AUC, ACC, Precision, and Recall. The results demonstrate that the deep autoencoder-based detection mechanism can effectively capture latent distribution patterns in enterprise-level ETL data streams and accurately identify diverse anomalies, providing reliable support for enterprise data processing and intelligent analysis.
