摘要

为了提高流形学习的鲁棒性,提出了一种自组织的几何降维模型。该模型通过数据流形的自主变形,提出了一种新的降维机制。提出了自主变形向量场来指导数据流形的变形。数据流形的平坦化是在数据点之间的虚拟弹性和斥力相互作用下的一种紧急行为。当流形演化为低维形状时,流形的拓扑结构保持不变。为了克服采样不均匀和邻域点误判问题,提出了软邻域算法。数据集的仿真实验结果证明了该方法的有效性,也表明该方法可以揭示数据集的隐式特征。对比实验表明,该方法具有较好的鲁棒性。

Learning by Autonomous Manifold Deformation with an Intrinsic Deforming Field
A self-organized geometric model is proposed for data dimension reduction to improve the robustness of manifold learning. In the model, a novel mechanism for dimension reduction is presented by the autonomous deforming of data manifolds. The autonomous deforming vector field is proposed to guide the deformation of the data manifold. The flattening of the data manifold is achieved as an emergent behavior under the virtual elastic and repulsive interaction between the data points. The manifold’s topological structure is preserved when it evolves to the shape of lower dimension. The soft neighborhood is proposed to overcome the uneven sampling and neighbor point misjudging problems. The simulation experiment results of data sets prove its effectiveness and also indicate that implicit features of data sets can be revealed. In the comparison experiments, the proposed method shows its advantage in robustness.
