This year, CLAD’s Conference on Classification and Data Analysis took place in a reduced format, taking into account the 17th IFCS Conference, IFCS 2022 – Classification and Data Science in the Digital Age.

The (mini)-JOCLAD 2022 took place at the Faculty of Economics of the University of Porto on the afternoon of 18 July, preceding the IFCS 2022.


The invited speaker was Prof. Berthold Lausen, from the University of Essex, who gave a lecture on Bootstrap Evaluation of Unsupervised Statistical Learning and Applications. The program included, as usual, sessions organized by Banco de Portugal and by Instituto Nacional de Estatística, which presented us recent and very interesting works developed in their institutions. JOCLAD 2022 was also the opportunity to honour the new CLAD Emeritus Members, Prof. Helena Bacelar-Nicolau and Prof. Paulo Gomes.

Participation was free, subject to prior registration.
