中文简介: | 我们考虑了形状约束下的非参数回归和图像分析中的几个问题。我们的任务总是生成局部极值较少的简单函数,而多分辨率准则保证了拟合函数的良好逼近。这些策略容易导致难以解决的最小化问题,因此设计有效的算法至关重要。我们研究的问题之一与在线数据有关,其中快速处理尤为重要。 |
课程简介: | We consider several problems in the areas of nonparametric regression and image analysis under shape constraints. The task is always to produce simple functions with small number of local extreme values, while multiresolution criteria ensure good approximation of the fitted functions. These strategies easily lead to minimisation problems that can be very difficult to solve, hence the design of efficient algorithms is crucial. One of the problems that we study is concerned with online data where fast processing is particularly important. |
