Anti Spam
Spam blocker tool
Anti Spam A new anti-spam software product has been launched at
digiportal.com which aims to remember which e-mails the recipient
regards as spam and which are to be kept.
ChoiceMail gives the user the option of flagging an e-mail when it is
first received as junk mail. Any subsequent messages received from the
same e-mail address will be prevented from entering the inbox. All
e-mails from first time senders will be held by ChoiceMail which then
asks the sender to go to a web site and input their name, e-mail address
and purpose for the e-mail. The form is then forwarded to the intended
recipient who chooses if they want to receive the e-mail.

The Goals of spam
The goal of spam
is to determine the intrinsic grouping in a set of unlabeled data. But
how to decide what constitutes a good spam? It can be shown that
there is no absolute “best” criterion which would be independent of the
final aim of the spam. Consequently, it is the user which must
supply this criterion, in such a way that the result of the spam
will suit their needs.
For instance, we could be interested in finding representatives for
homogeneous groups (data reduction), in finding “natural
clusters” and describe their unknown properties (“natural” data
types), in finding useful and suitable groupings (“useful” data
classes) or in finding unusual data objects (outlier detection).
