Most of manifold alignment algorithms can only give the predictive value of the training set instead of producing a mapping defined everywhere.

大多数流形对齐算法只能给出了训练集上的预测值，而没有给出整个数据空间上的映射关系。

As an effective manifold-learning method, the local tangent space alignment (LTSA) algorithm is sensitive to outliers.

局部切空间排列(LTSA)算法是一种有效的流形学习方法，但该算法对孤立点的存在非常敏感。
