Multi-Label Learning

Dear Colleagues,

In the last two decades, research on multi-label learning has received increasing attention, mainly because many real-world problems can be modeled under this learning paradigm. Such an interest can be appreciated in the continuous apparition of methods to different tasks, ranging from developing approaches for feature and instance selection, the correction of the imbalance between labels, noise detection, and the reduction of feature and label spaces, to the adaptation of algorithms to directly handling the multi-label data, the combination of active and semi-supervised approaches for constructing better classifiers, the development of methods for extreme multi-label classification, deep models, and so on. Multi-label learning is an exciting area that involves a set of challenges and difficulties that usually do not appear in other learning paradigms, such as the automatic modeling of inter-label correlations, treating the imbalance between labels, and the unfeasibility of using certain approaches to problems with a large number of labels. Despite the considerable number of existing works, several of the issues mentioned above remain open. Furthermore, it is necessary to continue the development of more efficient classifiers. Therefore, the aim of this Special Issue is to enhance the state-of-the-art in the multi-label learning area significantly. We exhort authors across the world to submit their original and unpublished works. We have an especial interest in works focusing on the topics listed below, but works attending other approaches will also be well received.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Algorithms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
