New method to improve DBSCAN clustering algorithm quality [PDF]
, 2008 针对基于密度带有"噪声"的空间聚类应用(DBSCAN)聚类算法存在的3个主要问题:输入参数敏感、对内存要求高、数据分布不均匀时影响聚类效果,提出了一种基于遗传方法的DBSCAN算法改进方案数据分区中使用遗传思想的DBSCAN算法(DPDGA)来提高聚类质量.利用遗传算法改进K-means算法来获取初始聚类中心;对数据进行划分,在此基础上对划分的每一部分使用DBSCAN算法进行聚类;合并聚类的结果.仿真实验表明,新方法较好解决了传统DBSCAN聚类算法存在的问题 ...

Faster DBScan and HDBScan in low-dimensional Euclidean spaces [PDF]
, 2019 We present a new algorithm for the widely used density-based clustering method dbscan. For a set of n points in 2 our algorithm computes the dbscan-clustering in O(nlog n) time, irrespective of the scale parameter (and assuming the second parameter ...

DyProL: Dynamic Ensemble Representation Learning for Protein–Nucleic Acid Binding Site Prediction
Advanced Science, EarlyView.Protein function is represented as a dynamic conformational ensemble rather than a single static structure. A multi‐conformation geometric attention framework aligns, clusters, and learns representative states to capture residue‐ and ensemble‐level signals. Integrating structural dynamics improves interpretable protein‐NA binding prediction and reveals
