Prejudicial Narratives: Building Tomorrow's World Today

Film production requires world building: the power to visualise and bring to life narrative through a film's total environment. This is often entirely speculative, imagining alternative or future worlds. Here, Alex McDowell , acclaimed British production designer, producer and Professor at the University of Southern California (USC) describes his world-building, narrative approach to production design, which he consolidated in the Steven Spielberg film Minority Report (2002) that envisioned Washington DC in the year 2050. The possibilities of this storytelling technique are demonstrated by its transference into real-life projects, such as the immersive model that his production company, 5D GlobalStudio, developed for Al Baydha, a Bedouin village in Saudi Arabia.     

ESPM--频繁子树挖掘算法

随着互联网的发展,频繁模式的挖掘由频繁项集扩展到结构化数据：树和图．在这些结构上的挖掘工作被应用于更为复杂的领域,比如生物信息学、网络日志和XML文档．提出了一个新颖的算法：ESPM,以挖掘有序标号树中的频繁子树．不同于以往的工作,把树同构的判断工作放到了算法的晚期,从而减少了整个挖掘过程的时间开销．人工数据集和真实数据集上的实验都证明ESPM相较于其他算法的优越性．还提出了一些可能的改进．
