LPQP FOR MAP INFERENCE ---------------------- This is the code implementing the LPQP algorithms introduced in: Patrick Pletscher & Sharon Wulff LPQP for MAP: Putting LP Solvers to Better Use ICML, 2012. The code was slightly modified after ICML and hence the results might differ a bit. We re-tested the grid experiments with this version of the code, and the results pretty much match the ones in the ICML paper. We did not re-run the protein & DTF experiments, but would expect roughly the same results as in the published paper. The tree-based LPQP weighting is implemented in LPQPSDD, the uniform weighting in LPQPNPBP. COMPILATION & INSTALL --------------------- The software was successfully compiled and tested on Ubuntu 12.04, CentOS 6 and Mac OS X 10.8. Compilation requires cmake, please make sure you have cmake installed on your system. 1. create a directory build/ 2. run ./fetch_external.sh 3. cd to build 4. run cmake 5. run make install 6. run make test to check whether everything runs as expected the library and the matlab wrappers are now installed into bin/ To use the wrapper in your own scripts, add the directory containing the mex_lpqp.mex* to the path within Matlab (using addpath). Remark: Make sure that the compiler optimizations are turned on (-O3), otherwise the code is *very* slow (probably has to do with the extensive use of Eigen).
