Baesyan filter - bug fixed (still test pre-release!)
Hello, tbdev. One bug has been fixed in filter baesyan. The bug was that if a letter contain token consists whole from ! then during degeneration an error occured and the filter failed. So, any letter includes this kind of tokens seemed to be non-spam because of this fail. Fixed version you can download here: http://klirik.narod.ru/arc/baesnolog.tbp http://klirik.narod.ru/arc/baes.tbp (I still recommend you to use last (logged) version to send me a log if any bug arises). For this moment no other serious errors found. In my own testing: since the first build I received 92 spam letters and about 25 non-spam (understand now, why I began to write the filter :). From these letters I has no false positives (i.e. none of my good mail was accidentally deleted as spam) and 1 false negative (i.e. one spam letter came to my mailbox). Also it were about 10 false positives raised because of the just fixed bug. I refiltered these letters after now and all of them were regarded as spam. So, total effectivity (for the moment) is: 0% (0 of 25) false positives and 1.1%(1 of 92) false negative. I use the regarding base of 650 spam and about 800 non-spam letters. In future: 1. New rbd-generating engine (principle is same, but will be changed user interface and some options added). Also it seems to be good to automatically recognize and do something with PGP- or S-MIME- encrypted messages - throw them at all or at least keep them as hash values due to reduce a dictionary. 2. Filter settings will be stored in the registry. Or - I found that if TBP_NeedConfig returns -1 then The Bat! himself adds a section [Filterdata] in TBPlugin.INI. Now this section is empty but I think in future The Bat! developers will give a possibility to store a settings locally for every mailbox (in registry it will be global settings). 3. Adapt rbd-generating to other mailbase formats - because as I know SecureBat is also exist and has his mailbases encrypted. This problem for this very program can be solved by other mailbase imported formats, for example, unix-mailbox. 4. Self-training feature. Now I guess it can be like a question to a user after every 50 received letters (for example) with asking him to confirm the grade of all letters - or, as a case - to confirm only questionable letters automatically regarded in some definite interval of spaminess (21-80% for example). After that new grade will be appended to regard.rbd. So, the base will be always fresh and it wouldn't be necessary to use rbd-generating engine to refresh it. This is my own ideas. If anyone else has some? -- Sincerely, Alexey.

Re[2]: problems with bayesian filter
Hello, rhabib001. You wrote in mid:[EMAIL PROTECTED] ryc One thing I don't understand about the log is that if multiple ryc messages are downloaded, the log doesn't reflect this. Is this a bug? As I understand myself, The Bat can call multiple instances of filtering procedure in a time. For this reason it give to every call a number, usually begins from 1001. By this reason I write into log also this unique number (it is unique in the bounds of current The Bat! session). You can see this numbers in the beginning of every line logged during mailcheck. And there are no such lines for global plugin functions like getname or getversion. Your log has combined the logs of first version and last, so there are no such numbers at all at the beginning of the log. If any of them includes a spam then the really problem is in your regarding base - either you confused spam and non-spam corpuses when you create your regarding base, either your regarding base is not enough yet. ryc I have trained the good dictionary on 745 letters, but the spam ryc dictionary on only 35 letters. Could this be the problem (I have ryc attached the regard.rdb file). This is the feature of method itself - you can investigate it from mathematically viewpoint - the numbers of spam and non-spam base (counted in letters) ought to be equal. Simple speaking, your base very well known what is not-spam, but has a relative hazy idea of what is spam. You need more spam to work, - but this is total problem with this method of filtering! You can, of course, download somewhere a base with spam, but the problem is that in different countries spam is different. Main grain of this method is that all user's regarding bases are different, because their grades includes also knowledge of concrete private user mail. So, it is very hard for spammers to cheat many of such filters simultaneously. From the other hand, spam base seems not to be such different from user to user, because spam is a mass mailing. So you can ask a friend to send you many (real) spam and make a better base. Or you can just take some good letters and make a new base with relatively equal quantity of spam and non-spam. -- Sincerely, Alexey.
