We consider the problem of searching for a best LAD-solution of an overdetermined system of linear equations Xa = z, X ∈ Rm×n, m ≥ n, a ∈ R, z ∈ R. This problem is equivalent to the problem of… (More)

In this paper a new fast partitioning algorithm able to find either a globally optimal partition or a locally optimal partition of the set A ⊂ R close to the global one is proposed. The performance… (More)

In this paper we construct an efficient adaptive Mahalanobis k-means algorithm. In addition, we propose a new efficient algorithm to search for a globally optimal partition obtained by using the… (More)

In this paper we consider a special nonlinear total least squares problem, where the model function is of the form $f(x;a,b)=\phi^{-1}(ax+b)$ . Using the fact that after an appropriate substitution,… (More)

Global hydrological cycles mainly depend on climate changes whose occurrence is predominantly triggered by solar and terrestrial influence, and the knowledge of the high water regime is widely… (More)
