D.MCA: Outlier Detection with Explicit Micro-Cluster Assignments
Shuli Jiang, Robson Leonardo Ferreira Cordeiro, Leman Akoglu
How can we detect outliers, both scattered and clustered, and also explicitly assign them to respective micro-clusters, without knowing apriori how many micro-clusters exist? How c…
C-AllOut: Catching & Calling Outliers by Type
Guilherme D. F. Silva, Leman Akoglu, Robson L. F. Cordeiro
Given an unlabeled dataset, wherein we have access only to pairwise similarities (or distances), how can we effectively (1) detect outliers, and (2) annotate/tag the outliers by ty…
StructMatrix: large-scale visualization of graphs by means of structure detection and dense matrices
Hugo Gualdron, Robson Cordeiro, Jose Rodrigues
Given a large-scale graph with millions of nodes and edges, how to reveal macro patterns of interest, like cliques, bi-partite cores, stars, and chains? Furthermore, how to visuali…
M-Flash: Fast Billion-scale Graph Computation Using a Bimodal Block Processing Model
Hugo Gualdron, Robson Cordeiro, Jose Rodrigues-Jr +3
Recent graph computation approaches have demonstrated that a single PC can perform efficiently on billion-scale graphs. While these approaches achieve scalability by optimizing I/O…
ORFEL: efficient detection of defamation or illegitimate promotion in online recommendation
Gabriel Gimenes, Robson Cordeiro, Jose F. Rodrigues-Jr
What if a successful company starts to receive a torrent of low-valued (one or two stars) recommendations in its mobile apps from multiple users within a short (say one month) peri…
