Learning-to-rank is one of the learning frameworks in machine learning and it aims to organize the objects in a particular order according to their preference, relevance or ranking. In this paper, we give a comprehensive survey for learning-to-rank. First, we discuss the different approaches ...
可能有叫做Master of Science in Machine Learning,Master of Science in Data Science,Master of Science in Human-Computer Interaction,etc. 念了关于资工方面的,并不是都叫做Master of Science in Computer Science, 当然要念最纯正原始的这种资工硕士还是有。
Oracle Machine Learningsupports pairwise and listwise ranking methods throughXGBoost. For a training data set, in a number of sets, each set consists of objects and labels representing their ranking. A ranking function is constructed by minimizing a certain loss function on the training data. Using...
