针对您提出的“unsupervised model selection for time-series anomaly detection”(无监督模型选择用于时间序列异常检测)的问题,以下是一个结构化的回答,旨在帮助您理解和实施这一过程: 1. 研究常见的无监督学习模型 在时间序列异常检测中,常见的无监督学习模型包括: 自编码器(Autoencoders):通过编码和解码过程重建输入...
Two themes have dominated the research on anomaly detection in time series data, one related to explorations of deep architectures for the task, and the other, equally important, the creation of large benchmark datasets. In line with the current trends, we have proposed several deep learning ...
To detect anomalies or anomalous regions in a collection of sequences or time series data, you can use an autoencoder. An autoencoder is a type of model that is trained to replicate its input by transforming the input to a lower dimensional space (the encoding step) and reconstructing the ...

AutoEncoder (AE) AE [39] is a semi-supervised reconstruction-based method for anomaly detection. AE tries to learn the normal pattern of the given data to minimize the reconstruction errors for normal instances. Then, new data instances with large reconstruction errors are considered anomalies. AE...
