About: Isomap

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Isomap is a nonlinear dimensionality reduction method. It is one of several widely used low-dimensional embedding methods. Isomap is used for computing a quasi-isometric, low-dimensional embedding of a set of high-dimensional data points. The algorithm provides a simple method for estimating the intrinsic geometry of a data manifold based on a rough estimate of each data point’s neighbors on the manifold. Isomap is highly efficient and generally applicable to a broad range of data sources and dimensionalities.

  • 等距特征映射是一个非线性降维方法，被广泛使用的低维嵌入方法之一。 等距特征映射被用来计算准等距的高维数据到低维的嵌入方法。算法通过将每个数据点和临近的数据点连接构成图，用图论中的dijkstra距离来估计流形的测地距离。等距特征映射十分高效，可以广泛的应用到各种来源和维数不同的数据。 (zh)
