Suspected word flip (more -> less)

[AlexEngelhardt]

In cost sensitive classification, shouldn't the more costly class be weighted up?

Hi Alex,

thanks very much, but I think the text is correct here. The intuition is that by weighting it up you make the less costly class a "safer bet" for standard classification methods concerned with keeping the error rate low. Hence the less costly class is predicted more often and the more expensive class is predicted only when the classifier is very sure.

Oh!

Thanks for the explanation. This makes sense. I had just misunderstood "costly class".

This can be closed, I suppose.

Closing then. Thanks for mindfully reading the tutorial.
