TopoLa: A Universal Framework to Enhance Cell Representations for Single-cell and Spatial Omics through Topology-encoded Latent Hyperbolic Geometry
Kai Zheng, Shaokai Wang, Yunpei Xu +8
Recent advances in cellular research demonstrate that scRNA-seq characterizes cellular heterogeneity, while spatial transcriptomics reveals the spatial distribution of gene express…
TopoLa: a novel embedding framework for understanding complex networks
Kai Zheng, Qilong Feng, Yaohang Li +3
Complex networks, which are the abstractions of many real-world systems, present a persistent challenge across disciplines for people to decipher their underlying information. Rece…
New Approximation Algorithms for Fair -median Problem
Di Wu, Qilong Feng, Jianxin Wang
The fair -median problem is one of the important clustering problems. The current best approximation ratio is 4.675 for this problem with 1-fair violation, which was proposed by…
An Improved FPT Algorithm for the Flip Distance Problem
Qilong Feng, Shaohua Li, Xiangzhong Meng +1
Given a set of points in the Euclidean plane and two triangulations of , the flip distance between these two triangulations is the minimum number of flips required…
Speeding Up Constrained -Means Through 2-Means
Qilong Feng, Bin Fu
For the constrained 2-means problem, we present a time algorithm. It generates a collection of approximate center pairs $(…
The Complexity of Tree Partitioning
Zhao An, Qilong Feng, Iyad Kanj +1
Given a tree on vertices, and , the Tree Partitioning problem asks if at most edges can be removed from so that the resulting componen…
Algorithms for Maximum Agreement Forest of Multiple General Trees
Feng Shi, Jianer Chen, Qilong Feng +2
The Maximum Agreement Forest (Maf) problem is a well-studied problem in evolutionary biology, which asks for a largest common subforest of a given collection of phylogenetic trees…
