In rapid static or kinematic positioning, especially with single frequency and shorter period GPS phase observations, the normal matrix may be weak multicollinear since the GPS satellite’s positions and geometries are changing slightly. Therefore the conventional least squares float solution may cause large biases due to the weak multicollinearity and thus make the ambiguity search techniques f...

The presence of abrupt changes, such as impulsive and load disturbances, commonly occur in applications, but make the state estimation problem considerably more difficult than in the standard setting with Gaussian process disturbance. Abrupt changes often introduce a jump in the state, and the problem is therefore readily and often treated by change detection techniques. In this paper, we take ...

We introduce a path following algorithm for L1-regularized generalized linear models. The L1-regularization procedure is useful especially because it, in effect, selects variables according to the amount of penalization on the L1-norm of the coefficients, in a manner that is less greedy than forward selection–backward deletion. The generalized linear model path algorithm efficiently computes so...
