Ensemble feature selection for multi‐label text classification: An intelligent order statistics approach
Sign Up to like & getrecommendations! Published in 2022 at "International Journal of Intelligent Systems"
DOI: 10.1002/int.23044
Abstract: Because of the overgrowth of data, especially in text format, the value and importance of multi‐label text classification have increased. Aside from this, preprocessing and particularly intelligent feature selection (FS) are the most important step… read more here.

DOI: 10.1007/s00158-020-02663-8
Abstract: This paper presents a worst-case approach to robust optimization of plane frame structures under variation in uncertain parameters. The optimization procedure is first implemented without considering uncertainty, resulting in an optimal structure that may be… read more here.

DOI: 10.1007/s11222-016-9697-3
Abstract: The r largest order statistics approach is widely used in extreme value analysis because it may use more information from the data than just the block maxima. In practice, the choice of r is critical.… read more here.
