Latent-Frequency Validity: Fast Spectral Editing with Screened Video-VAE Transfer Operators
Bowen Xue, Jiafeng Xiong, Xin Quan
Direct spectral editing in video-VAE latents can control noise, flicker, smoothness, and frequency content without a decode--filter--reencode pass. However, video VAEs may redistri…
Inferring Latent Intentions: Attributional Natural Language Inference in LLM Agents
Xin Quan, Jiafeng Xiong, Marco Valentino +1
Attributional inference, the ability to predict latent intentions behind observed actions, is a critical yet underexplored capability for large language models (LLMs) operating in…
GIIFT: Graph-guided Inductive Image-free Multimodal Machine Translation
Jiafeng Xiong, Yuting Zhao
Multimodal Machine Translation (MMT) has demonstrated the significant help of visual information in machine translation. However, existing MMT methods face challenges in leveraging…
Graph Structure Learning with Temporal Graph Information Bottleneck for Inductive Representation Learning
Jiafeng Xiong, Rizos Sakellariou
Temporal graph learning is crucial for dynamic networks where nodes and edges evolve over time and new nodes continuously join the system. Inductive representation learning in such…
Trajectory Encoding Temporal Graph Networks
Jiafeng Xiong, Rizos Sakellariou
Temporal Graph Networks (TGNs) have demonstrated significant success in dynamic graph tasks such as link prediction and node classification. Both tasks comprise transductive settin…
A Survey of Link Prediction in Temporal Networks
Jiafeng Xiong, Ahmad Zareie, Rizos Sakellariou
Temporal networks have gained significant prominence in the past decade for modelling dynamic interactions within complex systems. A key challenge in this domain is Temporal Link P…
