| Implementation of 'Maximum Likelihood Estimation of Intrinsic Dimension' by Elizaveta Levina and Peter J. Bickel | |
| how to use | |
| ---------- | |
| The goal is to estimate intrinsic dimensionality of data, the estimation of dimensionality is scale dependent | |
| (depending on how much you zoom into the data distribution you can find different dimesionality), so they | |
| propose to average it over different scales, the interval of the scales [k1, k2] are the only parameters of the algorithm. |
In general, check the crt/host_config.h file to find out which versions are supported.
Sometimes it is possible to hack the requirements there to get some newer versions working, too :)
Thrust version can be found in $CUDA_ROOT/include/thrust/version.h.
