The linear CPR-PLS in the high-dimensional feature space corresponds to a nonlinear CPR-KPLS in the original input space. This method offers a novel extension for kernel partial least squares regression(KPLS),and some numerical simulation results are presented to illustrate the feasibility of the proposed method.展开更多

Due to the diversity of individual's anthropometric measurements, the individualized customization technology is needed to get convincing sound. In this paper, we proposed a simple and effective method for modeling relationships between anthropometric measurements and Head-related Impulse Response(HRIR). Considering the relationship between anthropometric measurements and different HRIR parts is complicated, we divided the HRIRs into small segments and carried out regression analysis between anthropometric measurements and each segment to establish relationship model. The results of objective simulation and subjective test indicate that the model can generate individualize HRIRs from a series of anthropometric measurements. With the individualized HRIRs, we can get more accurate acoustic localization sense than using non-individualized HRIRs.展开更多

The article argues that the 2013 Granta list examines Williams＇ legacy from a twenty-first century perspective, offering a range of fictions that represent the rapidly changing socio-political, cultural and economic landscapes of contemporary Britain. Through textual analysis and contextualized readings, it suggests that the novels featured on the 2013 list do not offer a purely pastoral view of Britain, but use the natural world as a platform to stage wider discussions regarding a range of present-day issues.展开更多
