为此，提出了基于时空兴趣点局部时空特征的运动表示方法，实现了基于时空单词的动作识别。
This paper employs the motion representation based on space-time interest points and implements action recognition method based on spatiotemporal codebook and words.
正如在第一个实验里，心神在时空上游历得越远，能记住的单词就越少。
As in the first experiment, more words slipped away with greater distances traveled.
奇点这个单词来自于天体物理学：它指的是时空中(例如黑洞内部)所有物理理论都失效的一点。
The word singularity is borrowed from astrophysics: it refers to a point in space-time - for example, inside a black hole - at which the rules of ordinary physics do not apply.
