Thanks all, I am just thinking to build an anomaly (novelty) detector using one class SVM with manual inspection to detected anomaly as a feedback to update the normal model. i will think of something else :) Regards, AdyWP ---

Yes, unfortunately that's the nature of SVM. I However, there have been implementations with on-line learning capabilities for SVM that are (promised to be) nearly as accurate as the batch learning variant. Maybe the partial_fit could be a useful task for the GitHub "issue" list. Here would be
