In this case, the learning-to-rank problem is approximated by a classification problem — learning a binary classifier (,) that can tell which document is better in a given pair of documents. The classifier shall take two documents as its input and the goal is to minimize a loss function L ( h ; x u , x v , y u , v ) {\displaystyle L(h;x_{u},x ...

For example, there were lower madrasas and specialised ones, and for one to get into the specialised area meant that he had to complete the classes in the lower one in order to adequately prepare himself for higher learning. [14] This is the rank of madrasas in the Ottoman Empire from the highest ranking to the lowest: (From İnalcık, 167). [14]
Academic study of the history of science as an independent discipline was launched by George Sarton at Harvard with his book Introduction to the History of Science (1927) and the Isis journal (founded in 1912). Sarton exemplified the early 20th century view of the history of science as the history of great men and great ideas.
Academic rank (also scientific rank) is the rank of a scientist or teacher in a college, high school, university or research establishment. The academic ranks indicate relative importance and power of individuals in academia. The academic ranks are specific for each country, there is no worldwide-unified ranking system.
A knowledge society generates, shares, and makes available to all members of the society knowledge that may be used to improve the human condition. [1] A knowledge society differs from an information society in that the former serves to transform information into resources that allow society to take effective action, while the latter only creates and disseminates the raw data.

As another example, the ordinal data hot, cold, warm would be replaced by 3, 1, 2. In these examples, the ranks are assigned to values in ascending order, although descending ranks can also be used. Ranks are related to the indexed list of order statistics, which consists of the original dataset rearranged into ascending order.
In 2012, the head of AP Grading, Trevor Packer, stated that the reason for the low percentages of 5s is that "AP World History is a college-level course, & many sophomores aren't yet writing at that level." 10.44 percent of all seniors who took the exam in 2012 received a 5, while just 6.62 percent of sophomores received a 5.
