As we know, the mobile device screen is small. The lower accuracy of the model is relatively weak and the capacity to handle high detailed model is very limited. What’s more, the existing three-dimensional simplification algorithms are for the personal computer and they are not suitable for the mobile terminals. Thus, we propose a novel 3D model simplification algorithm based on feature points....

This paper gives a general methodology for symbolic programming of complex 3D scenes and animations. It also introduces a minimal set of animation primitives for the functional geometric language PLaSM. The symbolic approach to animation design and implementation given in this paper goes beyond the traditional two-steps approach to animation, where a modeler is coupled, more or less loosely, wi...

Lie derivatives are widely used in mathematics and physics. They are usually computed symbolically using computer algebra software. This symbolic computation might fail for very complicated expressions. Moreover, symbolic differentiation becomes more difficult if the function to be differentiated is not described explicitly as a function but by an algorithm. This is a situation occuring quite o...

This paper investigates the effects of early stopping as a method to counteract overfitting in evolutionary data modelling using Genetic Programming. Early stopping has been proposed as a method to avoid model overtraining, which has been shown to lead to a significant degradation of out-of-sample performance. If we assume some sort of performance metric maximisation, the most widely used early...
