| 英文摘要 |
| The density peaks clustering algorithm can deal with datasets quickly and efficiently without iteration. How-ever, it can sometimes wrongly select cluster centers and misallocate samples when processing manifold data. Therefore,
this paper proposes the density peaks clustering algorithm based on shared nearest neighbor and second-order K nearest
neighbor for manifold data (DPC-SKNN) algorithm. Firstly, the algorithm introduces reverse nearest neighbors and shares
nearest neighbors to redefine local density, fully considering both local and global information of samples, making the al-gorithm easier to identify correct cluster centers. Secondly, the association relationship of the samples is divided into three
types: K nearest neighbors, second-order K nearest neighbors, and non-nearest neighbors, and design allocation strategies
for K-nearest neighbors to enhance similarity among samples within the same cluster, thereby improving sample allocation
accuracy. DPC-SKNN is compared with eight algorithms on manifold and UCI datasets, and the experimental results show
that the DPC-SKNN algorithm obtains good clustering results on all the above datasets. |
