| ---------------------- |
| |
| - edit your copy of Bayes.pm so that $self->{log_raw_counts} = 1; . This will |
| cause the Bayes code to write the raw counts to stdout, so that the |
| bayes-analyse-from-raw-counts script can dump a cost calculation and |
| histogram very quickly, while still recalculating the probabilities with |
| different values for the constants, and using different combining techniques. |
| |
| - Next, run a 10-pass cross-validation run using bayes-10pcv-driver on your |
| test corpus. |
| |
| - Edit run-search and change the system()s around line 41 to refer to the |
| spam_all.log and nonspam_all.log files from the run above. |
| |
| - To test with chi-squared combining, edit the run-search script and change |
| $USE_CHI_COMBINING to 1 instead of 0. |
| |
| - Run |
| |
| ./run-search | tee search.results |
| |
| This will pick random values for the constants in question, run |
| bayes-analyse-from-raw-counts for that combination, and dump a line |
| with the resulting cost figures. |
| |
| - While this is running -- or at the end after 1k iterations, if you're very |
| patient -- run gnuplot, and paste in the commands from gnuplot.cmds. This |
| will map the surface representing the cost figures for each combination of |
| the constants. |
