  abstract =     "Recent research shows that incorporating semantic
                 knowledge into the genetic programming (GP)
                 evolutionary process can improve its performance. This
                 work proposes an angle-aware mating scheme for
                 geometric semantic crossover in GP for symbolic
                 regression. The angle-awareness guides the crossover
                 operating on parents which have a large angle between
                 their relative semantics to the target semantics. The
                 proposed idea of angle-awareness has been incorporated
                 into one state-of-the-art geometric crossover, the
                 locally geometric semantic crossover. The experimental
                 results show that, compared with locally geometric
                 semantic crossover and the regular GP crossover, the
                 locally geometric crossover with angle-awareness not
                 only has a significantly better learning performance
                 but also has a notable generalisation gain on unseen
                 test data. Further analysis has been conducted to see
                 the difference between the angle distribution of
                 crossovers with and without angle-awareness, which
                 confirms that the angle-awareness changes the original
                 distribution of angles by decreasing the number of
                 parents with zero degree while increasing their
                 counterparts with large angles, leading to better
