Node Feature Extraction by Self-Supervised Multi-scale Neighborhood Prediction

4 code implementations29 Oct 2021 Eli Chien, Wei-Cheng Chang, Cho-Jui Hsieh, Hsiang-Fu Yu, Jiong Zhang, Olgica Milenkovic, Inderjit S Dhillon

We also provide a theoretical analysis that justifies the use of XMC over link prediction and motivates integrating XR-Transformers, a powerful method for solving XMC problems, into the GIANT framework.

Highly Scalable and Provably Accurate Classification in Poincare Balls

1 code implementation8 Sep 2021 Eli Chien, Chao Pan, Puoya Tabaghi, Olgica Milenkovic

For hierarchical data, the space of choice is a hyperbolic space since it guarantees low-distortion embeddings for tree-like structures.

You are AllSet: A Multiset Function Framework for Hypergraph Neural Networks

no code implementations24 Jun 2021 Eli Chien, Chao Pan, Jianhao Peng, Olgica Milenkovic

We propose AllSet, a new hypergraph neural network paradigm that represents a highly general framework for (hyper)graph neural networks and for the first time implements hypergraph neural network layers as compositions of two multiset functions that can be efficiently learned for each task and each dataset.

Linear Classifiers in Product Space Forms

no code implementations19 Feb 2021 Puoya Tabaghi, Eli Chien, Chao Pan, Jianhao Peng, Olgica Milenković

Embedding methods for product spaces are powerful techniques for low-distortion and low-dimensional representation of complex data structures.

Adaptive Universal Generalized PageRank Graph Neural Network

1 code implementation ICLR 2021 Eli Chien, Jianhao Peng, Pan Li, Olgica Milenkovic

We address these issues by introducing a new Generalized PageRank (GPR) GNN architecture that adaptively learns the GPR weights so as to jointly optimize node feature and topological information extraction, regardless of the extent to which the node labels are homophilic or heterophilic.

Support Estimation with Sampling Artifacts and Errors

no code implementations14 Jun 2020 Eli Chien, Olgica Milenkovic, Angelia Nedich

Here we introduce the first known approach to support estimation in the presence of sampling artifacts and errors where each sample is assumed to arise from a Poisson repeat channel which simultaneously captures repetitions and deletions of samples.

Active learning in the geometric block model

no code implementations15 Nov 2019 Eli Chien, Antonia Maria Tulino, Jaime Llorca

Galhotra et al. recently proposed a motif-counting algorithm for unsupervised community detection in the geometric block model that is proved to be near-optimal.

Multi-MotifGAN (MMGAN): Motif-targeted Graph Generation and Prediction

no code implementations8 Nov 2019 Anuththari Gamage, Eli Chien, Jianhao Peng, Olgica Milenkovic

Generative models are successful at retaining pairwise associations in the underlying networks but often fail to capture higher-order connectivity patterns known as network motifs.

Landing Probabilities of Random Walks for Seed-Set Expansion in Hypergraphs

no code implementations20 Oct 2019 Eli Chien, Pan Li, Olgica Milenkovic

We describe the first known mean-field study of landing probabilities for random walks on hypergraphs.
