So I am trying to understand what is happening with my dspam install and why it is working well for some users and not at all for one.
I created a dspam user (intended to be corpus fed and used as a merged group), following this tutorial from Stevan: http://sourceforge.net/p/dspam/mailman/message/29158188/ I fed it some spam and ham and then started testing to see how it does. Below is a result that I don’t understand. Shouldn’t the FN be incrementing instead of the TN when I feed it a spam with “—class spam”? (the email that i am feeding it, “test-3”, is a short spam message which has no dspam headers) # dspam_stats -H dspamr dspamr: TP True Positives: 12301 TN True Negatives: 1358 FP False Positives: 5 FN False Negatives: 191 SC Spam Corpusfed: 0 NC Nonspam Corpusfed: 0 TL Training Left: 1137 SHR Spam Hit Rate 98.47% HSR Ham Strike Rate: 0.37% PPV Positive predictive value: 99.96% OCA Overall Accuracy: 98.59% # cat test-3 | dspam --user dspamr --mode toe --class spam --source inoculate --stdout # dspam_stats -H dspamr dspamr: TP True Positives: 12301 TN True Negatives: 1359 FP False Positives: 5 FN False Negatives: 191 SC Spam Corpusfed: 0 NC Nonspam Corpusfed: 0 TL Training Left: 1136 SHR Spam Hit Rate 98.47% HSR Ham Strike Rate: 0.37% PPV Positive predictive value: 99.96% OCA Overall Accuracy: 98.59% #cat test-3 | dspam --user dspamr --mode toe --stdout --classify X-DSPAM-Result: dspamr; result="Innocent"; class="Innocent"; probability=0.0000; confidence=0.76; signature=N/A ------------------------------------------------------------------------------ Subversion Kills Productivity.
