30(Scary) usage:
31usage: ./svmwrap
32 -i <filename>: training set or DB to screen
33 --feats <int>: number of features
34 [-o <filename>]: predictions output file
35 [-np <int>]: ncores
36 [--kernel <string>] choose kernel type {Lin|RBF|Sig|Pol}
37 [-c <float>]: fix C
38 [-e <float>]: epsilon in the loss function of epsilon-SVR;
39 (0 <= epsilon <= max_i(|y_i|))
40 [-g <float>]: fix gamma (for RBF and Sig kernels)
41 [-r <float>]: fix r for the Sig kernel
42 [--iwn]: turn ON instance-wise-normalization
43 [--scale]: turn ON [0:1] scaling (NOT PRODUCTION READY)
44 [--no-plot]: no gnuplot
45 [{-n|--NxCV} <int>]: folds of cross validation
46 [-q]: quiet
47 [-v|--verbose]: equivalent to not specifying -q
48 [--seed <int>]: fix random seed
49 [-p <float>]: training set portion (in [0.0:1.0])
50 [--pairs]: read from .AP files (atom pairs; will offset feat. indexes by 1)
51 [--train <train.liblin>]: training set (overrides -p)
52 [--valid <valid.liblin>]: validation set (overrides -p)
53 [--test <test.liblin>]: test set (overrides -p)
54 [{-l|--load} <filename>]: prod. mode; use trained models
55 [{-s|--save} <filename>]: train. mode; save trained models
56 [-f]: force overwriting existing model file
57 [--scan-c]: scan for best C
58 [--scan-e <int>]: epsilon scan #steps for SVR
59 [--scan-g]: scan for best gamma
60 [--regr]: regression (SVR); also, implied by -e and --scan-e
61 [--e-range <float>:<int>:<float>]: specific range for e
62 (semantic=start:nsteps:stop)
63 [--c-range <float,float,...>] explicit scan range for C
64 (example='0.01,0.02,0.03')
65 [--g-range <float,float,...>] explicit range for gamma
66 (example='0.01,0.02,0.03')
67 [--r-range <float,float,...>] explicit range for r
68 (example='0.01,0.02,0.03')
