space dimensionality

The extension of reinforcement learning to MDPs with large state, action space and high complexity has inevitably encountered the problem of the curse of dimensionality, which results in slow convergence and long training time.

传统的强化学习算法应用到大状态、动作空间和任务复杂的马尔可夫决策过程问题时，存在收敛速度慢，训练时间长等问题。

It takes much time to detect edges of color images directly. To resolve this problem, reduce the dimensionality of color image space ( RGB), while keep the gray moments of tristimulus values invariable to reserve as much as possible the main characteristics of the original images.

针对彩色图像边缘检测计算量大的弱点，对彩色图像空间（RGB）进行三基色降维处理，保持图像的各个基色的灰度矩不变，以最大限度地保留原图像的主要特征。

Dimensionality reduction process can be divided into two steps. The first step is to select pivot points to determine the coordinate axes in a target space.

降维过程主要分为两步，首先通过选择枢纽点确定目标空间中的坐标轴，然后计算数据集中的样本点在这些坐标轴上的投影坐标。

The detailed content can be illustrated as follows. Firstly, already proposed dimensionality reduction cause unboundedness of searching space, so subsequence similarity search algorithm can not effectively filter the point in the index.

首先，原有降维技术造成序列数据搜索空间无界性，使得子序列相似查询算法在索引遍历时不能充分实现点过滤。
