We appreciate the support from Google, Priberam and Feedzai, thanks to which a limited number of scholarships will be provided. Detailed instructions about how to apply will be posted shortly.

  • In partnership with Google, we will provide a limited number of grants that cover the registration. The grants may cover travel, accommodation, and registration expenses. Only PhD and Post-Doc students are eligible (priority will be given to PhD students). Grants will be given according to the relevance of the applicant’s work in the fields of machine learning and natural language processing.
  • Priberam will also provide grants covering the registration (no travel expenses will be covered by these grants). Any master student from a Portuguese institution is eligible, as long as she/he does not have any affiliation to a lab that could provide the funding. Preference will be given to early-year students who have top academic performance and interests in machine learning and/or natural language processing.
  • Feedzai is proud to provide grants covering the LxMLS 2015 registration. Any Msc. or Phd student, with Portuguese or foreign nationality is eligible. Preference is given to students near their degree completion who have top academic performance and are experienced or interested in classification, highly unbalanced datasets or very large scale problems.
