Leaping Through Time with Gradient-based Adaptation for Recommendation

1 code implementation11 Dec 2021 Nuttapong Chairatanakul, Hoang NT, Xin Liu, Tsuyoshi Murata

Different from the popular recurrent modeling approach, we propose a new solution named LeapRec to the temporal dynamic problem by using trajectory-based meta-learning to model time dependencies.

Adaptive Stacked Graph Filter

no code implementations1 Jan 2021 Hoang NT, Takanori Maehara, Tsuyoshi Murata

We study Graph Convolutional Networks (GCN) from the graph signal processing viewpoint by addressing a difference between learning graph filters with fully-connected weights versus trainable polynomial coefficients.

Frequency Analysis for Graph Convolution Network

no code implementations25 Sep 2019 Hoang NT, Takanori Maehara

In this work, we develop quantitative results to the learnablity of a two-layers Graph Convolutional Network (GCN).

Revisiting Graph Neural Networks: All We Have is Low-Pass Filters

2 code implementations23 May 2019 Hoang NT, Takanori Maehara

However, we find that the feature vectors of benchmark datasets are already quite informative for the classification task, and the graph structure only provides a means to denoise the data.
