The 8th International Workshop on Detection, Classification, Localization, and Density Estimation of marine mammals using passive acoustics will take place at the University Pierre et Marie Curie in Paris, France, 4-8 June 2018.

The DCLDE Workshop brings together researchers and engineers from universities, research institutes, government organizations, and industry, dealing with all aspects of acoustics, signal processing, pattern recognition, mathematics, and computer sciences applied to the study of the biology, ethology and ecology of marine mammals and also their environment and the potential effects of anthropogenic activities. The goal is to provide a forum for exchange of new results obtained from the latest advances in instrumentation and from the recent methods. Also this workshop will clearly encourage interdisciplinary approaches to create more knowledge on these species.

The DCLDE Workshop will comprise a prominent series of thematic sessions of oral and poster presentations. Abstracts will be published in proceedings to be made available to all registered participants on the first day of the Workshop.

As the previous sessions of the DCLDE workshops, a challenge is offered to compare methods, algorithms, and results. This time will be awarded the team that will best detect and classify the underwater acoustic environment including sounds emitted by mysticeti and odontoceti species among other biological, natural and anthropogenic noises.

Thematic Tutorial Sessions

Two thematic tutorial sessions will be organized on Monday 4th. The objective is to present the new theory, the current methods and the software used by the researchers. During 3-4 hours, overall presentation and examples on real recorded sounds will illustrate the knowledge, the advantages/inconvenient, and the use of these methods.

The 2 sessions are:
  • Machine learning (Deep learning) for Bioacoustics : learning regresentation, organized by Prof. H. Glotin, LIS
  • A primer on density estimation from passive acoustic data, organized by Dr. L. Thomas, Dr. T. Marques, and Dr. D. Harris, St Andrews


As the previous sessions of the DCLDE International Workshops, a challenge is offered to compare methods, algorithms, and results. For this 2018 DCLDE International Workshop, the challenge will be dedicated to the detection and classification of different mysticeti and odontoceti species among other biological, natural and anthropogenic noises. The dataset will be segmented in 3 parts: training, validation and test. Only the test part will be used to determine the winner of this challenge.

The dataset is provided by Prof. John Hildebrand, Scripps Institution of Oceanography, University of California San Diego, USA. You can download this dataset here.

The challenge is organized by Prof. J. Hildebrand, O. Adam and H. Glotin, and will be moderated by Prof. H. Glotin and J. Hildebrand.


An industrial exhibition is organized to allow companies that work in underwater acoustics, bioacoustics, signal processing, and pattern recognition. Companies will come to show their professional services and their materials. Demonstrations could be proposed if they do not disrupt the conference and are safe for all participants.
