| 摘 要： | 局部线性嵌入算法（LLE）因其较低的计算复杂度和高效性适用于很多降维问题,新的自适应局部线性嵌入（ALLE）算法对数据进行非线性降维,提取高维数据的本质特征,并保持了数据的全局几何结构特征,对比实验结果表明了该算法对于非理想数据的降维结果均优于LLE算法。

| Abstract: | Locally Linear Embedding algorithm (LLE) for its low computational complexity and efficiency of dimensionality reduction applied to many problems,the new adaptive local linear embedding (ALLE) algorithm is non-linear dimensionality reduction of data,extracting high-dimensional essential characteristics of the data and maintain the global geometry of data features,compared to experimental results show that the algorithm results show that the ALLE data for the non-ideal results were better than the LLE dimens... |
