    • openAccess   Solving weighted least squares (WLS) problems on arm-based architectures 

      BELLOCH, JOSE A.; Bank, Balázs; Igual, Francisco D.; Quintana-Orti, Enrique S.; Vidal, Antonio M. Springer (2016-11)
      The Weighted Least Squares algorithm (WLS) is applied to numerous optimization problems, but requires the use of high computational resources, especially when complex arithmetic is involved. This work aims to accelerate ...

    • openAccess   Spatial reasoning about qualitative shape compositions. Composing Qualitative Lengths and Angles 

      Falomir, Zoe; Pich Rubert, Albert; Costa, Vicent Springer (2020-06-24)
      Shape composition is a challenge in spatial reasoning. Qualitative Shape Descriptors (QSD) have proven to be rotation and location invariant, which make them useful in spatial reasoning tests. QSD uses qualitative ...
