Learning spatial relationships in hand-drawn patterns using fuzzy mathematical morphology

Adrien Delaye, Eric Anquetil
2010 2010 International Conference of Soft Computing and Pattern Recognition  
We introduce in this work a new approach for learning spatial relationships between elements of hand-drawn patterns with the help of fuzzy mathematical morphology operators.  ...  Relying on mathematical morphology allows to take into account the actual shapes of hand-drawn patterns when modeling their spatial relationships, and thus to cope with the variability of handwriting signal  ...  If much research effort has been spent for improving the modeling of isolated shapes [PS00] , most models for relative positioning rely on a rather simple description that consists in summarizing each  ...

The Relationship between Handedness and Mathematics Is Non-linear and Is Moderated by Gender, Age, and Type of Task

Giovanni Sala, Michela Signorelli, Giulia Barsuola, Martina Bolognese, Fernand Gobet
2017 Frontiers in Psychology  
The results show that (a) linear and quadratic functions are insufficient for capturing the link between handedness and mathematical ability; (b) the percentage of variance in mathematics scores explained  ...  In accordance with previous research, handedness does represent a correlate of achievement in mathematics, but the shape of this relationship is more complicated than has been argued so far.  ...  Gender Analysis Regression analysis showed that H 4 was still a predictor of the dependent variable (mathematics scores) for males (b 4 = −0.779, t = −2.649, r = 0.212, R 2 = 0.045, p = 0.009; intercept  ...
