PDF for the numerical (FFT) convolution of two PDFs.

This class implements a generic one-dimensional numeric convolution of two PDFs, and can convolve any two RooAbsPdfs.

The class exploits the convolution theorem

\[ f(x) * g(x) \rightarrow F(k_i) \cdot G(k_i) \]

to calculate the convolution by calculating a Real->Complex FFT of both input PDFs, multiplying the complex coefficients and performing the reverse Complex->Real FFT to get the result in the input space. This class uses the ROOT FFT interface to the (free) FFTW3 package (www.fftw.org), and requires that your ROOT installation is compiled with the fftw3=ON (default). Instructions for manually installing fftw below.

Note that the performance in terms of speed and stability of RooFFTConvPdf is vastly superior to that of RooNumConvPdf.

An important feature of FFT convolutions is that the observable is assumed to be cyclical. This is correct for cyclical observables such as angles, but does not hold in general. For non-cyclical variables, wrap-around artifacts may be encountered, e.g. if the PDF is zero at xMin and non-zero at xMax. A rising tail may appear at xMin. This is inevitable when using FFTs. A distribution with 3 bins therefore looks like:

... 0 1 2 0 1 2 0 1 2 ...

Therefore, if bins 0 and 2 are not equal, the FFT sees a cyclical function with a step at the 2|0 boundary, which causes artifacts in Fourier space.

The spillover or discontinuity can be reduced or eliminated by introducing a buffer zone in the FFT calculation. If this feature is activated (on by default), the sampling array for the FFT calculation is extended in both directions, and padded with the lowest/highest bin. Example:

original:                -5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5
add buffer zones:    U U -5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5 O O
rotate:              0 +1 +2 +3 +4 +5 O O U U -5 -4 -3 -2 -1

The buffer bins are stripped away when the FFT output values are transferred back to the p.d.f cache. The default buffer size is 10% of the observable domain size, and can be changed with the setBufferFraction() member function.

The RooFFTConvPdf uses caching inherited from a RooAbsCachedPdf. If it is evaluated for a particular value of x, the FFT and convolution is calculated for all bins in the observable space for the given choice of parameters, which are also stored in the cache. Subsequent evaluations for different values of the convolution observable and identical parameters will be retrieved from the cache. If one or more of the parameters change, the cache will be updated, i.e., a new FFT runs.

The sampling density of the FFT is controlled by the binning of the the convolution observable, which can be changed using RooRealVar::setBins(N). For good results, N should be large (>=1000). Additional interpolation between the bins may improve the result if coarse binnings are chosen. These can be activated in the constructor or by calling setInterpolationOrder(). For N >> 1000, interpolation will not substantially improve the accuracy.

Additionial information on caching can be displayed by monitoring the message stream with topic "Caching" at the INFO level, i.e. by calling RooMsgService::instance().addStream(RooMsgService::INFO,Topic("Caching")) to see these message on stdout.

Multi-dimensional convolutions are not supported at the moment.

Installing an external version of FFTW on Linux and compiling ROOT to use it

You have two options:

Recommended: ROOT can automatically install FFTW for itself, see builtin_fftw3 at https://root.cern.ch/building-root
Install FFTW and let ROOT discover it. fftw3 is on by default (see https://root.cern.ch/building-root)

1) Go to www.fftw.org and download the latest stable version (a .tar.gz file)

If you have root access to your machine and want to make a system installation of FFTW

2) Untar fftw-XXX.tar.gz in /tmp, cd into the untarred directory and type './configure' followed by 'make install'. This will install fftw in /usr/local/bin,lib etc...

3) Start from a source installation of ROOT. ROOT should discover it. See https://root.cern.ch/building-root

If you do not have root access and want to make a private installation of FFTW

2) Make a private install area for FFTW, e.g. /home/myself/fftw

3) Untar fftw-XXX.tar.gz in /tmp, cd into the untarred directory and type './configure –prefix=/home/myself/fftw' followed by 'make install'. Substitute /home/myself/fftw with a directory of your choice. This procedure will install FFTW in the location designated by you

4) Start from a source installation of ROOT. Look up and set the proper paths for ROOT to discover FFTW. See https://root.cern.ch/building-root

		RooRealVar &	convVar,
		RooAbsPdf &	pdf1,

		Int_t	ipOrder = `2`
	)

Constructor for numerical (FFT) convolution of PDFs.

Parameters

[in]	name	Name of this PDF
[in]	title	Title for plotting this PDF
[in]	convVar	Observable to convolve the PDFs in

Attention: Use a high number of bins (>= 1000) for good accuracy.

Parameters

◆ actualObservables()

RooArgSet * RooFFTConvPdf::actualObservables ( const RooArgSet & nset ) const

protectedvirtual

Return the observables to be cached given the normalization set nset.

If the cache observable is in nset then this is

the convolution observable plus
any member of nset that is either a RooCategory,
or was previously specified through setCacheObservables().

In case the cache observable is not in nset, then it is

the convolution observable plus
all member of nset that are observables of this p.d.f.

◆ actualParameters()

RooArgSet * RooFFTConvPdf::actualParameters ( const RooArgSet & nset ) const

	)		const

protectedvirtual

Create appropriate generator context for this convolution.

If both input p.d.f.s support internal generation, if it is safe to use them and if no observables other than the convolution observable are requested for generation, use the specialized convolution generator context which implements a smearing strategy in the convolution observable. If not return the regular accept/reject generator context

◆ getMaxVal()

virtual Int_t RooFFTConvPdf::getMaxVal ( const RooArgSet & vars ) const

◆ setBufferFraction()

Change the size of the buffer on either side of the observable range to frac times the size of the range of the convolution observable.

Definition at line 864 of file RooFFTConvPdf.cxx.

◆ setBufferStrategy()

void RooFFTConvPdf::setBufferStrategy ( BufStrat bs )

Change strategy to fill the overflow buffer on either side of the convolution observable range.

Extend means is that the input p.d.f convolution observable range is widened to include the buffer range
Flat means that the buffer is filled with the p.d.f. value at the boundary of the observable range
Mirror means that the buffer is filled with a mirror image of the p.d.f. around the convolution observable boundary

The default strategy is extend. If one of the input p.d.f.s is a RooAddPdf, it is configured so that the interpretation range of the fraction coefficients is kept at the nominal convolutions observable range (instead of interpreting coefficients in the widened range including the buffer).
