This paper is written with two purposes in mind. First, it points out some mistakes made in the paper \Optimal deconvolution lter design based on orthogonal principle", recently published in this journal. Secondly, in order to sort out the reason for those mistakes, the relations between inner{ outer factorization, spectral factorization, whitening lters and Diophantine equations in MMSE lter d...

Secondary receivers in Multiple-Input Multiple-Output (MIMO) Cognitive Radio (CR) networks combat interference from primary transmitters while equipped with whitening filters. However, when the MIMO secondary users are employing Radio Frequency (RF) beam-forming networks at the transmitter/ receiver front ends to improve the MIMO transmission performance, the whitening filters cannot perform in...

In recent years, many dental professionals have changed their philosophy regarding the use of trays with at-home bleaching regimens. However, facts do not change--and successful vital tooth bleaching still occurs only when tooth surfaces are in direct contact with the appropriate concentration of active whitening agent for a specific amount of time. Because the science of tooth whitening is sti...

Whitening is a critical normalization method to enhance statistical reduction via reparametrization unit covariance. This article introduces the notion of whitening for random functions assumed reside in real separable Hilbert space. We compare properties different transformations stemming from factorization bounded precision operator under particular geometrical structure. The practical perfor...

Many deployed learned models are black boxes: given input, returns output. Internal information about the model, such as the architecture, optimisation procedure, or training data, is not disclosed explicitly as it might contain proprietary information or make the system more vulnerable. This work shows that such attributes of neural networks can be exposed from a sequence of queries. This has ...

In this paper, we analyze two recently proposed closed-loop subspace identification methods, referred to as innovation estimation method and whitening filter approach respectively. The similarity and difference between them are investigated in detail. It turns out that all closed-loop subspace identification methods can be classified as one-step, two-step, or multi-stage projection methods. A S...

Prewhitening is often considered a necessary but not sufficient condition for stronger stochastic independence criteria. After prewhitening the task of Blind Source Separation (BSS) become somewhat easier. Robust preprocessing involves spectral whitening, which is done by transforming correlated signals to an uncorrelated flat spectrum signal. The maximum entropy power spectrum estimation has b...

At this time there are many ways to promote or advertise products attract consumers. One of the methods used is endorsement and influencer. This was also done by Scarlett whitening who influencer Tasya Farasya. study aims analyze identify relationship between endorsements influencers on buying interest in Scarlet Whitening products. The theory which has 4 indicators, namely: transactional inter...
