2 # pattern_mm - Harvest patterns from game collection and compute feature strengths
4 # This is a "frontend" for the MM tool by Remi Coulom, that is assumed to be
5 # unpacked and compiled in the mm/ subdirectory - get it at
7 # http://remi.coulom.free.fr/Amsterdam2007/mm.tar.bz2
9 # It will scan a given SGF collection, collect patterns, and use the MM tool
10 # to compute the relative strength of various features. The output will be
12 # * patterns.gamma: Gamma values of pattern features
13 # * patterns.gammaf: Gamma values of pattern features for MC simulations
15 # If you haven't done so yet, you should first run ./pattern_spatial_gen.sh
16 # (probably in the competition scan mode) to initialize the spatial patterns
17 # dictionary for the collection.
19 # If you run this on hundreds of games, be sure you are doing it on local
20 # filesystem, with some free memory (and few GB of free disk on both
21 # local fs and in /tmp for temporary data), and armed by a lot of patience
22 # - it can take long time (minutes, tens of minutes...).
