This paper is concerned with studying the forgetting factor of the recursive least square (RLS). A new dynamic forgetting factor (DFF) for RLS algorithm is presented. The proposed DFF-RLS is compared to other methods. Better performance at convergence and tracking of noisy chirp sinusoid is achieved. The control of the forgetting factor at DFF-RLS is based on the gradient of inverse correlation...

Our research is to develop the low-complexity broadband microphone beamformer which has robustness to moving interference signal. In this paper, an improved broadband GSC-RLS beamformer structure with fast self-tuning algorithm is proposed. Also, the improved fast self-tuning algorithm for the proposed GSC-RLS structure is developed, based on the Song‟s method. The computational complexity of t...

Recently, recursive least square (RLS), or extended Kalman ltering (EKF), based algorithms have been demonstrated to be a class of eeective online training methods for neural networks. This paper discusses several aspects of pruning a neural network trained by the RLS based approach. Based on our study, the RLS approach is implicitly a weight decay training algorithm. Also, we derive two prunin...

The recursive least squares (RLS) algorithm is one of the most popular adaptive algorithms that can be found in the literature, due to the fact that it is easily and exactly derived from the normal equations. In this paper, we give another interpretation of the RLS algorithm and show the importance of linear interpolation error energies in the RLS structure. We also give a very efficient way to...

Migraine and restless legs syndrome (RLS) appear to be associated, but the relationship between tension-type headache (TTH) and RLS is unknown. This nationwide, population-based, retrospective cohort study explored the potential association between TTH and RLS.We identified 15,504 patients with newly diagnosed TTH from 2000 to 2007 and 62,016 individuals without TTH who were selected by frequen...

OBJECTIVE To evaluate the association between white matter lesion (WML) volume, silent infarcts and restless legs syndrome (RLS) in a population-based study of elderly individuals. DESIGN Cross-sectional study. SETTING Population-based Three-City study. PARTICIPANTS 1035 individuals from the Dijon, France, centre of the Three-City study who had available information on volume of WMLs from...

We commend Gemignani and colleagues for important observations 1 on the prevalence of Restless Legs Syndrome (RLS) in 104 patients with symptoms of exclusive small fiber neuropa-thy, peripheral neuropathy, or mononeuropathy multiplex. The co-occurrence of neuropathy and RLS has been studied from two standpoints in the past, without reaching a consensus: the frequency of neuropathy in RLS patien...

dopamine agonists, particularly nonergot dopamine agonists such as pramipexole, have become the mainstay of therapy for patients with symptoms of restless legs syndrome (rls). this study was designed to evaluate the factors affecting the efficacy of pramipexole in patients with rls. fifty-nine eligible rls patients referred to neurology clinic of rasoul-e-akram hospital (tehran, iran) were recr...

In our previous cross-sectional study, we found that restless legs syndrome (RLS) was associated with erectile dysfunction (ED). Thus, we conducted a prospective study to examine whether RLS was associated with a higher risk of developing ED based on 6 years of follow-up among 10,394 men (mean age = 63.4 years) in the Health Professionals Follow-up Study. RLS was assessed in 2002 using a set of...
