RECURRENCE PLOTS

Should be the same. I have to check. Perhaps there is another norm selected or the time series was normalised by default. Do you have a short example? I could use it to check the code.

The 10th international recurrence plot symposium will most likely by organized by the National Institute of Advanced Industrial Science and Technology in Tsukuba, Japan, in August 28-30, 2023. The venue will be in Tsukuba.

Hi, I guess with "radius" you mean the recurrence threshold ε? There are really many ideas out now to identify the "optimal" recurrence threshold ε. However, it really depends on the research question. If you like to compare two time series with CRP, it might be best to use simpl...

The multivariate RP is nothing else than using the different time series as the different components of the phase space vector. Therefore, there is no difference to the standard approach, as far as I see it.

The threshold selection depends on the research question and the data. If your data has many outliers or behaves like from a non-stationary process, a normalisation and using a threshold in units of the standard deviation might not be the best choice. Then consider the slecetion that preserves a pre...

Dir sir： I use CRP toolbox ，i have some puzzle about the function ‘crp(x,m,t,e)’ and ‘pss’； e represent the threshold，but when i choose the norm ‘euclidean’，and set the e =2，like 'crp(x,3,1,2,'euclidean')',I noticed that there is a title on the picture ‘Dimention:3 Delay:1 threshold: 2σ’ ，i dont ko...

Dear all, For a noisy time series, it is mentioned in the literature that the threshold should be around 5*sigma. I wanted to ask if this sigma is the standard deviation of the time series? No, it is the standard deviation of the observation noise. This threshold value (5σ) is actually much too hig...

Thanks for your reply. :mrgreen: I am looking forward to this. Will I be able to submit an abstract for a poster presentation in the registration portal when it opens? ~ Aaron Yes, sure! You are warmly welcome! Send me an email with your email address to get included in the list for announcements.

Sir my topic of research is the nonlinear analysis of solar wind. My doubt is, “is it possible to use cross recurrence plot to study similarity in the dynamics of solar wind speed and the interplanetary magnetic field. Hi, before answering this question, we should be clear about the research questi...

The ninth international recurrence plot symposium will be organized by the Lublin University of Technology, Poland, in September 22-24, 2021. The venue will be in Lublin.

Hi,
yes, we plan a mixture of physical and virtual conference.
You are warmly welcome to join!

For the next symposium in 2019, we offer a scholarship for PhD students! More info: http://symposium.recurrence-plot.tk/?a=scholarship

This is completely right. For the measures based on vertical structures, I suggest to include the LOI and not to apply the Theiler window. This should also be noted in the explanation of the method when a publication is prepared.

This is really a good point. When the LOI is not excluded, the denominator is N × N . There are some special cases where this definition of RR is helpful. In other applications, it can be required to exclude the LOI, then the denominator is N ( N –1). Further, a Theiler window can be required, which...

As far as I know, there is no public software for it. I myself have developed a C++ code but it is only for a pilot study and I need to check again whether it is maturated enough to be used for general purpose or other data. Moreover, the code is more than 10 years old …
