 guido perhaps more useful would be if tim could check in the pickle s generated by one of his training runs so that others can see how tim s training data performs against their own corpora tim i did that yesterday but seems like nobody bit i downloaded and played with it a bit but had no time to do anything systematic it correctly recognized a spam that slipped through sa but it also identified as spam everything in my inbox that had any mime structure or html parts and several messages in my saved zope geeks list that happened to be using mime and or html so i guess i ll have to retrain it yes you told me so just in case wink i uploaded a new version just now since mincount went away unknown_spamprob is much less likely and there s almost nothing that can be pruned away so the file is about NUMBERx larger now URL i ll try this when i have time guido van rossum home page URL
