摘要:

自适应共振理论(ART)因其能够处理可塑性-稳定性矛盾而被认为是实现持续学习的有效途径。然而,一般来说,基于ART的算法的聚类性能强烈依赖于相似性阈值的指定,即,警惕参数,取决于数据并手动指定。本文提出了一种基于ART的拓扑聚类算法,该算法具有根据数据点的分布自动估计相似性阈值的机制。此外,为了提高信息抽取的性能,通过引入层次结构,提出了一种具有持续学习能力的分层层次聚类算法.实验结果表明,该算法具有较高的聚类性能与最近提出的最先进的层次聚类算法。

英文摘要:

Adaptive Resonance Theory (ART) is considered as an effective approach for realizing continual learning thanks to its ability to handle the plasticity-stability dilemma. In general, however, the clustering performance of ART-based algorithms strongly depends on the specification of a similarity threshold, i.e., a vigilance parameter, which is data-dependent and specified by hand. This paper proposes an ART-based topological clustering algorithm with a mechanism that automatically estimates a similarity threshold from the distribution of data points. In addition, for improving information extraction performance, a divisive hierarchical clustering algorithm capable of continual learning is proposed by introducing a hierarchical structure to the proposed algorithm. Experimental results demonstrate that the proposed algorithm has high clustering performance comparable with recently-proposed state-of-the-art hierarchical clustering algorithms.
