Rank based Least-squares Independent Component Analysis
In this paper, we propose a nonparametric rank-based alternative to the least-squares independent component analysis algorithm developed. The basic idea is to estimate the squared-loss mutual information, which used as the objective function of the algorithm, based on its copula density version. Therefore, no marginal densities have to be estimated. We provide empirical evaluation of th...
متن کاملA weighted least squares method for inverse dynamic analysis.
Internal forces in the human body can be estimated from measured movements and external forces using inverse dynamic analysis. Here we present a general method of analysis which makes optimal use of all available data, and allows the use of inverse dynamic analysis in cases where external force data is incomplete. The method was evaluated for the analysis of running on a partially instrumented ...
متن کاملSelectively Damped Least Squares for Inverse Kinematics
We introduce a method of selectively damped least squares (SDLS) for inverse kinematics, designed for multibodies with multiple end effectors. This method is compared with Jacobian transpose and damped least squares methods. SDLS has advantages in converging in fewer iterations, in not requiring ad hoc damping constants, and in converging quickly to reachable targets. Experiments show the impor...
متن کاملRecursive least squares with stabilized inverse factorization
Recently developed recursive least squares schemes, where the square root of both the covariance and the information matrix are stored and updated, are known to be particularly suited for parallel implementation. However, when finite precision arithmetic is used, round-off errors apparently accumulate unboundedly, so that after a number of updates the computed least squares solutions turn out t...
متن کاملLeast-Squares Mass-Dependence Molecular Structures.
The major part of the difference between the zero-point and equilibrium moment of inertia of a molecule is a homogeneous function of degree 12 in the atomic masses. The use of explicit mathematical models of is studied here as a means of determining near-equilibrium molecular structures from the zero-point moments of inertia of a range of isotopomers. It is found that models with more than two ...
