Asymptotic smoothing errors for hidden Markov models
In this paper, the asymptotic smoothing error for hidden Markov models (HMMs) is investigated using hypothesis testing ideas. A family of HMMs is studied parametrised by a positive constant , which is a measure of the frequency of change. Thus, when 0, the HMM becomes increasingly slower moving. We show that the smoothing error is ( ). These theoretical predictions are confirmed by a series of ...
متن کاملGaussian Smoothing and Asymptotic Convexity
Smoothing (say by a Guassian kernel) has been a very popular technique for optimizing a nonconvex objective function. The rationale behind smoothing is that the smoothed function has less spurious local minima than the original one. This technique has seen tremendous success in many real world tasks such as those arising in machine learning and computer vision. Despite its empirical success, th...
متن کاملTheoretical fits of the δ Cephei light , radius and radial velocity curves
We present a theoretical investigation of the light, radius and radial velocity variations of the prototype δ Cephei. We find that the best fit model accounts for luminosity and velocity amplitudes with an accuracy better than 0.8σ, and for the radius amplitude with an accuracy of 1.7σ. The chemical composition of this model suggests a decrease in both helium (0.26 vs 0.28) and metal (0.01 vs 0...
متن کاملSmoothing of Ribbons over Curves
We prove that ribbons, i.e. double structures associated with a line bundle E over its reduced support, a smooth irreducible projective curve of arbitrary genus, are smoothable if their arithmetic genus is greater than or equal to 3 and the support curve possesses a smooth irreducible double cover with trace zero module E . The method we use is based on the infinitesimal techniques that we deve...

Using BCrier-techniques or B-spline-techniques for lntrrpolation or approximation of cur\es or wrfaces inflection pants or changes of sign of the Gaussian curvature occaaionallq occur. Inflection polnth or changer of sign of Gaussian curvature are ur&vwd in some applications. notably the fairlng of ship liner or the fairlng of car body surfaces. In the present contribution we mtroduce ~1 simple...
