Unifying Least Squares, Total Least Squares and Data Least Squares
The standard approaches to solving overdetermined linear systems Ax ≈ b construct minimal corrections to the vector b and/or the matrix A such that the corrected system is compatible. In ordinary least squares (LS) the correction is restricted to b, while in data least squares (DLS) it is restricted to A. In scaled total least squares (Scaled TLS) [15], corrections to both b and A are allowed, ...
متن کاملEfficient AUC Maximization with Regularized Least-Squares
Area under the receiver operating characteristics curve (AUC) is a popular measure for evaluating the quality of binary classifiers, and intuitively, machine learning algorithms that maximize an approximation of AUC should have a good AUC performance when classifying new examples. However, designing such algorithms in the framework of kernel methods has proven to be challenging. In this paper, ...
متن کاملEfficient Multimodal Registration Using Least-Squares
The sum of squared differences (SSD) cost function has generally been overlooked for multimodal registration problems. More recently, methods that employ SSD have been developed to efficiently evaluate the global optimal shift and intensity remapping. However, these methods estimate translations and not rotations. In this paper we propose a method to extend the efficiency of the Least Squares M...
متن کاملEfficient Sparse Recovery Pursuits with Least Squares
We present a new greedy strategy, with an efficient implementation technique, that enjoys similar computational complexity and stopping criteria like OMP. Moreover, its recovery performance in the noise free and the Gaussian noise cases is comparable and in many cases better than other existing sparse recovery algorithms both with respect to the theoretical and empirical reconstruction ability....
متن کاملLeast – Squares Method For Estimating Diffusion Coefficient
Abstract: Determination of the diffusion coefficient on the base of solution of a linear inverse problem of the parameter estimation using the Least-square method is presented in this research. For this propose a set of temperature measurements at a single sensor location inside the heat conducting body was considered. The corresponding direct problem was then solved by the application of the ...
