ListWise’s approach to email list cleaning is quite unique. ListWise first checks the email provider MX records, to make sure it is a valid mail server. Then ListWise does a real-time SMTP handshake with the email provider to check the validity of each individual email address.

Web30 apr. 2024 · Our approach to ranking is of the pairwise kind, i.e. it takes two documents and decides which one is more relevant than the other. This approach comes with some difficulties, as, to achieve a consistent and unique ranking, the model has to define an order. Web6 mrt. 2024 · Listwise approach These algorithms try to directly optimize the value of one of the above evaluation measures, averaged over all queries in the training data. This is difficult because most evaluation measures are not continuous functions with respect to ranking model's parameters, and so continuous approximations or bounds on evaluation …
