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:
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:
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.
You have two options:
builtin_fftw3
at https://root.cern/building-rootfftw3
is on by default (see https://root.cern/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/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/building-root

Return the strategy currently used to fill the buffer: '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

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

Advertise capability to determine maximum value of function for given set of observables.
If no direct generator method is provided, this information will assist the accept/reject generator to operate more efficiently as it can skip the initial trial sampling phase to empirically find the function maximum

Scan the values of 'pdf' in observable 'obs' using the bin values stored in 'hist' at slice position 'slicePos' N is filled with the number of bins defined in hist, N2 is filled with N plus the number of buffer bins The return value is an array of doubles of length N2 with the sampled values.

void RooFFTConvPdf::setBufferFraction | ( | double | frac | ) |

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 rangeFlat
means that the buffer is filled with the p.d.f. value at the boundary of the observable rangeMirror
means that the buffer is filled with a mirror image of the p.d.f. around the convolution observable boundaryThe 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).
