摘要

我们提出了一个鲁棒主成分分析(RPCA)框架来从时间观测中恢复低秩和稀疏矩阵。为了处理更大的数据集或流数据，我们开发了一个在线版本的批处理时序算法。我们将所提出的方法与不同的RPCA框架进行了实证比较，并在实际情况中展示了它们的有效性。

Robust PCA for Anomaly Detection and Data Imputation in Seasonal Time Series

We propose a robust principal component analysis (RPCA) framework to recover low-rank and sparse matrices from temporal observations. We develop an online version of the batch temporal algorithm in order to process larger datasets or streaming data. We empirically compare the proposed approaches with different RPCA frameworks and show their effectiveness in practical situations.
