Unlike prior principal component analysis (PCA)-based approaches, we do not store the entire data matrix or covariance matrix, and thus our approach is

In this section, distributed MVE-PCA is examined in environments with differing network topologies. Two types of topologies are used; a fully connected network and random

By oversampling the target instance and extracting the principal direction of the data, the proposed osPCA allows us to determine the anomaly of the target

To tackle this problem, we propose an adaptive RPCA (ARPCA) to recover the clean data from the high-dimensional corrupted data. Our proposed model is advantageous due to: 1) The

Here authors used the properties of intrusion detection system and anomaly detection system which are prebuilt in principal component analysis if used properly.Tests are

Figure 4 shows distance-distance plots for the car data, using standard and robust PCA, and their sparse versions, resulting in four different plots.. The robust distance-distance
