  • About CCF Ranking: The Chinese Computing Federation (CCF) Ranking provides a ranking of peer-reviewed journals and conferences in the field of computer science.

  • About Core Ranking: The CORE Conference Ranking is a measure to assess the major conference in the computing field. This ranking is governed by the CORE Executive Committee. To know more about Core ranking, visit Core ranking portal.

  • About Qualis Ranking: This conference ranking is published by the Brazilian ministry of education. It uses the h-index as a performance metric to rank conferences. Conferences are classified into performance groups that range from A1 (to the best), A2, B1, B2,..., B5 (to the wost). To know more about qualis ranking, visit here

Conference Call for paper


We invite submissions of papers addressing theoretical aspects of machine learning and related topics. We strongly support a broad definition of learning theory, including, but not limited to:-Design and analysis of learning algorithms-Statistical and computational complexity of learning-Optimization methods for learning-Unsupervised, semi-supervised, online and active learning-Interactions with other mathematical fields-Interactions with statistical physics-Artificial neural networks, including deep learning-High-dimensional and non-parametric statistics-Learning with algebraic or combinatorial structure-Geometric and topological data analysis-Bayesian methods in learning-Planning and control, including reinforcement learning-Learning with system constraints: e.g. privacy, memory or communication budget-Learning from complex data: e.g., networks, time series, etc.-Learning in other settings: e.g. social, economic, and game-theoreticSubmissions by authors who are new to COLT are encouraged. While the primary focus of the conference is theoretical, the authors may support their analysis by including relevant experimental results.All accepted papers will be presented in a single track at the conference. At least one of each paper’s authors should be present at the conference to present the work. Accepted papers will be published electronically in the Proceedings of Machine Learning Research (PMLR). The authors of accepted papers will have the option of opting-out of the proceedings in favor of a 1-page extended abstract. The full paper reviewed for COLT will then be placed on the arXiv repository.Paper Awards:COLT will award both best paper and best student paper awards. To be eligible for the best student paper award, the primary contributor(s) must be full-time students at the time of submission. For eligible papers, authors must indicate at submission time if they wish their paper to be considered for a student paper award. The program committee may decline to make these awards, or may split them among several papers.Dual Submissions:Submissions that are substantially similar to papers that have been previously published, accepted for publication, or submitted in parallel to other peer-reviewed conferences with proceedings may not be submitted to COLT. The same policy applies to journals, unless the submission is a short version of a paper submitted to a journal, and not yet published. Authors must declare such dual submissions either through the Easychair submission form, or via email to the program chairs.Formatting:Submissions are limited to 12 PMLR-formatted pages, plus unlimited additional pages for references and appendices. All details, proofs and derivations required to substantiate the results must be included in the submission, possibly in the appendices. However, the contribution, novelty and significance of submissions will be judged primarily based on the main text (without appendices), and so enough details, including proof details, must be provided in the main text to convince the reviewers of the submissions’ merits. Formatting and submission instructions can be found here.Rebuttal Phase:As in previous years, there will be a rebuttal phase during the review process. Initial reviews will be sent to authors before final decisions have been made. Authors will have the opportunity to provide a short response on the PC’s initial evaluation.Open Problems Session:We also invite submission of open problems. A separate call for open problems will be made available on the conference website.

Submission Deadline


COLT 2019: Annual Conference on Learning Theory submission deadline is 2019-02-01.

Note: It is generally recommended to submit your conference paper on or before the submission deadline. Generally, conferences do not encourage to submit the research paper after the deadline is over. In rare scenarios, conferences extend their deadline.
