Although many methods have been published to date, only few of them are suitable for use in automated pipelines or for processing large datasets. These use cases require stability and speed, which disqualifies many of the recently introduced tools that are either template based or available only ...
Learning to rank as one of machine learning techniques has been widely used in document categorization, information retrieval, text processing, product rating, and other ranking problem domains. Ranking task has become an interesting research in terms of big data and analytics in data mining. Meanwhi...
For example, in Document Retrieval the goal is to rank documents from a collection based on their relevancy to a user's query. Recently the supervised learning of ranking functions has attracted considerable attention from the Machine Learning community and most computational models proposed for ...
