      Santin, Andreu; Uriz, Maria-Jesus; Cristobo, Javier; Xavier, Joana R.; Rios, Pilar (Journal article; Peer reviewed, 2021)
      Sponges are amongst the most difficult benthic taxa to properly identify, which has led to a prevalence of cryptic species in several sponge genera, especially in those with simple skeletons. This is particularly true for ...

    • Unitary Branching Programs: Learnability and Lower Bounds 

      Diaz Andino, Fidel Ernesto; Kokkou, Maria; Oliveira, Mateus De Oliveira; Vadiee, Farhad (Journal article; Peer reviewed, 2021)
      Bounded width branching programs are a formalism that can be used to capture the notion of non-uniform constant-space computation. In this work, we study a generalized version of bounded width branching programs where ...
