说明: LSA的第一步是要去创建词到标题(文档)的矩阵。在这个矩阵里,每一个索引词占据了一行,每一个标题占据一列。每一个单元(cell)包含了这个词出现在那个标题中的次数。例如,词”book”出现在T3中一次,出现在T4中一次,而”investing”在所有标题中都出现了一次。一般来说,在LSA中的矩阵会非常大而且会非常稀疏(大部分的单元都是0)。这是因为每个标题或者文档一般只包含所有词汇的一小部分。更复杂的LSA算法会利用这种稀疏性去改善空间和时间复杂度。(The Little Book of Common SenseInvesting: The Only Way to Guarantee Your Fair Share of StockMarket Returns ,)

RRT-path-panning-algorithm
本文以自主驾驶车辆为实际应用背景.提出了一种改进的RRT(快速随机搜索树)路径规划算法.该路
径规划算法将非完整性约束条件与双向多步扩展RRT搜索算法相结合,在提高搜索效率的同时保证了规划路径的可
行性.同时将路径点作为B样条基函数的控制点,用三次B样条函数来拟合控制点生成平滑可跟踪的路径.通过在平
