What is pointwise ranking?
Pointwise ranking: A learning-to-rank approach that treats each item independently, predicting its relevance score or label with regression or classification, then sorts by prediction. It is simple but ignores the relative order among items.
Pointwise ranking: an example
Predict a 0 to 4 relevance for each search result separately, then sort.
