Traffic Data Restoration Method Based on Tensor Weighting and Truncated Nuclear Norm [PDF]
The problem of missing data seriously affects a series of activities in intelligent transportation systems,such as monitoring traffic dynamics,predicting traffic flow,and deploying traffic planning through data.Therefore,a traffic flow data ...

Difference-based Methods for Truncating the Singular Value Decomposition [PDF]
Given a noisy time series (or signal), one may wish to remove the noise from the observed series. Assuming that the noise-free series lies in some low dimensional subspace of rank r, a common approach is to embed the noisy time series into a Hankel trajectory matrix.

A New Algorithm for Ill-Posed Problem of GNSS-Based Ionospheric Tomography
Ill-posedness of GNSS-based ionospheric tomography affects the stability and the accuracy of the inversion results. Truncated singular value decomposition (TSVD) is a common algorithm of ionospheric tomography reconstruction.

An Improved Tikhonov-Regularized Variable Projection Algorithm for Separable Nonlinear Least Squares
In this work, we investigate the ill-conditioned problem of a separable, nonlinear least squares model by using the variable projection method. Based on the truncated singular value decomposition method and the Tikhonov regularization method, we propose ...
