As we can notice from right-top, the steady-state MSD can be below -21 dB if values of (γ 1, γ 2) are properly chosen in the fused-ZA-ATC algorithm, while the minimal steady-state MSD is only around -16.15 dB in the ZA-ATC algorithm, which indicates that the fused-ZA-ATC.
Download PDFAbstract: Heterogeneous information networks (HINs) with rich semantics are ubiquitousin real-world applications. For a given HIN, many reasonable clustering resultswith distinct semantic meaning can simultaneously exist. User-guided clusteringis hence of great practical value for HINs where users provide labels to asmall portion of nodes. To cater to a broad spectrum of user guidance evidencedby different expected clustering results, carefully exploiting the signalsresiding in the data is potentially useful. Meanwhile, as one type of complexnetworks, HINs often encapsulate higher-order interactions that reflect theinterlocked nature among nodes and edges. Network motifs, sometimes referred toas meta-graphs, have been used as tools to capture such higher-orderinteractions and reveal the many different semantics. We therefore approach theproblem of user-guided clustering in HINs with network motifs. In this process,we identify the utility and importance of directly modeling higher-orderinteractions without collapsing them to pairwise interactions. To achieve this,we comprehensively transcribe the higher-order interaction signals to a seriesof tensors via motifs and propose the MoCHIN model based on joint non-negativetensor factorization. This approach applies to arbitrarily many, arbitraryforms of HIN motifs. An inference algorithm with speed-up methods is alsoproposed to tackle the challenge that tensor size grows exponentially as thenumber of nodes in a motif increases. We validate the effectiveness of theproposed method on two real-world datasets and three tasks, and MoCHINoutperforms all baselines in three evaluation tasks under three differentmetrics. Additional experiments demonstrated the utility of motifs and thebenefit of directly modeling higher-order information especially when userguidance is limited.

Abstract: Multi-view networks are broadly present in real-world applications. In themeantime, network embedding has emerged as an effective representation learningapproach for networked data. Therefore, we are motivated to study the problemof multi-view network embedding with a focus on the optimization objectivesthat are specific and important in embedding this type of network. In ourpractice of embedding real-world multi-view networks, we explicitly identifytwo such objectives, which we refer to as preservation and collaboration. Thein-depth analysis of these two objectives is discussed throughout this paper.In addition, the mvn2vec algorithms are proposed to (i) study how varied extentof preservation and collaboration can impact embedding learning and (ii)explore the feasibility of achieving better embedding quality by modeling themsimultaneously. With experiments on a series of synthetic datasets, alarge-scale internal Snapchat dataset, and two public datasets, we confirm thevalidity and importance of preservation and collaboration as two objectives formulti-view network embedding. These experiments further demonstrate that betterembedding can be obtained by simultaneously modeling the two objectives, whilenot over-complicating the model or requiring additional supervision. The codeand the processed datasets are available atthis http URL.
