Enhanced Principal Tensor Analysis as a tool for 3-way geological data reconstructions

Principal tensor analysis (PTA) is considered as a potentially useful tool in geosciences, particularly for reconstructions of multi-way (time (depth), space, and proxies) datasets. We introduce an extension of PTA: PTA enhanced with Singular Spectrum Analysis (SSA). Using this enhancement, we were able to isolate clear patterns in noisy multi-way data. As an illustrative example, the method has been applied to 4-way data tensor (time, space,...
