Structure Aware Incremental Learning with Personalized Imitation Weights for Recommender Systems

no code implementations2 May 2023 Yuening Wang, Yingxue Zhang, Antonios Valkanas, Ruiming Tang, Chen Ma, Jianye Hao, Mark Coates

In contrast, for users who have static preferences, model performance can benefit greatly from preserving as much of the user's long-term preferences as possible.

Contrastive Learning for Time Series on Dynamic Graphs

no code implementations21 Sep 2022 Yitian Zhang, Florence Regol, Antonios Valkanas, Mark Coates

We propose a framework called GraphTNC for unsupervised learning of joint representations of the graph and the time-series.

Bag Graph: Multiple Instance Learning using Bayesian Graph Neural Networks

1 code implementation22 Feb 2022 Soumyasundar Pal, Antonios Valkanas, Florence Regol, Mark Coates

Since a meaningful graph representing dependencies between bags is rarely available, we propose to use a Bayesian GNN framework that can generate a likely graph structure for scenarios where there is uncertainty in the graph or when no graph is available.

Motion Inbetweening via Deep $Δ$-Interpolator

1 code implementation18 Jan 2022 Boris N. Oreshkin, Antonios Valkanas, Félix G. Harvey, Louis-Simon Ménard, Florent Bocquelet, Mark J. Coates

We show that the task of synthesizing human motion conditioned on a set of key frames can be solved more accurately and effectively if a deep learning based interpolator operates in the delta mode using the spherical linear interpolator as a baseline.
