In probability theory, a stochastic process , or sometimes random process (widely used) is a collection of random variables; this is often used to represent the evolution of some random value, or system, over time. This is the probabilistic counterpart to a deterministic process (or deterministic system). Instead of describing a process which can only evolve in one way (as in the case, for example, of solutions of an ordinary differential equation), in a stochastic or random process there is some indeterminacy: even if the initial condition (or starting point) is known, there are several (often infinitely many) directions in which the process may evolve. -Wiki

1.An Architectural Approach To Level Design 2014; 2.英文原版,PDF格式; 3.内容简介: This is a book about level design. It is also about how to look at designed space, which game levels, environments, and worlds most certainly are. Real-world architecture, urban environments, and gardens are also designed spaces. At some point, a designer (it doesn’t matter which kind; design is mostly universal) sat down to solve a problem that could only be solved by designing an interactive space. This problem could be how to best capture sunlight coming through a window, embody a religious idea, accentuate an important clue to solving a puzzle, or provide the best position for fragging competitors in an online game. Sometimes these spaces are loved by the people who use them, whether it is a home to raise a family, a plaza to enjoy a latte and some people watching, or a city in which to shoot gangsters and jump cars off of piers. Comparing level design and architecture can be very simple. It can also allow us to reveal things about both we have not seen before. This book reflects on both based on how they solve problems and create meaningful experiences for those using them. From these reflections, this book provides an architectural approach to level design that emphasizes spatial design for maximum user engagement.

另一个关键字提取器（Yake） 使用文本功能自动提取关键字的无监督方法。 AKE！ 是一种轻量级无监督自动关键字提取方法，该方法基于从单个文档中提取的文本统计特征来选择文本中最重要的关键字。 我们的系统不需要针对特定​​的文档集进行培训，也不必依赖于字典，外部语料库，文本大小，语言或领域。 为了展示我们建议的优点和重要性，我们将其与十种最新的无监督方法（TF.IDF，KP-Miner，RAKE，TextRank，SingleRank，ExpandRank，TopicRank，TopicalalPageRank，PositionRank和MultipartiteRank）进行比较，以及一种监督方法（KEA）。 在二十个数据集之上进行的实验结果（请参见下面的基准部分）表明，在许多不同大小，语言或领域的集合下，我们的方法明显优于最新方法。 除了此处描述的python包之外，我们还提供了一个，
