CLLMRec: Contrastive Learning with LLMs-based View Augmentation for Sequential Recommendation

IJCAI 2025

Sequential recommendation generates embedding representations from historical user-item interactions to recommend the next potential interaction item. Due to the complexity and variability of historical user-item interactions, extracting effective user features is quite challenging. Recent studies h

HyperLoRA: Parameter-Efficient Adaptive Generation for Portrait Synthesis

CVPR 2025highlight

Personalized portrait synthesis, essential in domains like social entertainment, has recently made significant progress. Person-wise fine-tuning based methods, such as LoRA and DreamBooth, can produce photorealistic outputs but need training on individual samples, consuming time and resources and po…

I2VControl: Disentangled and Unified Video Motion Synthesis Control

ICCV 2025poster

Motion controllability is crucial in video synthesis. However, most previous methods are limited to single control types, and combining them often results in logical conflicts. In this paper, we propose a disentangled and unified framework, namely I2VControl, to overcome the logical conflicts. We re…

MEGAD: A Memory-Efficient Framework for Large-Scale Attributed Graph Anomaly Detection

IJCAI 2025

Graph anomaly detection (GAD), with its ability to accurately identify anomalous patterns in graph data, plays a vital role in areas such as network security, social media platforms, and fraud detection. Graph autoencoder-based methods are widely used for GAD due to their efficiency and effectivenes

Where Does This Data Come From? Enhanced Source Inference Attacks in Federated Learning

IJCAI 2025

Federated learning (FL) enables collaborative model training without exposing raw data, offering a privacy-aware alternative to centralized learning. However, FL remains vulnerable to various privacy attacks that exploit shared model updates, including membership inference, property inference, and g

DynSNN: A Dynamic Approach to Reduce Redundancy in Spiking Neural Networks

ICASSP 2022accepted

Current Internet of Things (IoT) embedded applications use machine learning algorithms to process the collected data. However, the computational complexity and storage requirements of existing deep learning methods hinder the wide availability of embedded applications. Spiking Neural Networks (SNN)…
