------- Additional Comments From [EMAIL PROTECTED] 2005-08-03 19:49 ------- Subject: Re: Score generation for SpamAssassin 3.1 FWIW, the data from scoreset 3 more closely supports using the equation (bayes_group-50)/(50/3.5) to calculate the score. This is quite close to Justin's values above 50, but departs considerably at lower Bayes values: Group Set 3 Norm 3.5 Justin 2 Justin 3 0 -2.600 -3.500 -2.312 -2.599 5 -0.410 -3.150 -1.110 -1.110 20 -1.950 -2.100 -0.740 -0.740 40 -1.100 -0.700 -0.185 -0.185 50 0.000 0.000 0.001 0.001 60 0.370 0.700 1.000 1.000 80 2.090 2.100 2.000 2.000 95 2.060 3.150 3.000 3.000 99 1.890 3.430 3.500 3.500 The "Norm 3.5" group matching the above equation is very close to the Perceptron scores for Bayes_20 to Bayes_80. The Perceptron score for Bayes_05 is just plain wonky, and of course the scores flatten completely at Bayes_80. Running a simple linear solution to approximate the bayes-20 to bayes-80 scores with a straight line produces a slightly lower value for the constant (3.5) above: 3.3875. This of course produces slightly less aggessive scores on the top and bottom ends: Group Set 3 Norm 3.3875 0 -2.600 -3.388 5 -0.410 -3.049 20 -1.950 -2.033 40 -1.100 -0.678 50 0.000 0.000 60 0.370 0.678 80 2.090 2.033 95 2.060 3.049 99 1.890 3.320 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
