CroPS: Improving Dense Retrieval with Cross-Perspective Positive Samples in Short-Video Search

AAAI 2026technical

Dense retrieval has become a foundational paradigm in modern search systems, especially on short-video platforms. However, most industrial systems adopt a self-reinforcing training pipeline that relies on historically exposed user interactions for supervision. This paradigm inevitably leads to a fil

Decoupling Defense Strategies for Robust Image Watermarking

CVPR 2026

Deep learning-based image watermarking, while robust against conventional distortions, remains vulnerable to advanced adversarial and regeneration attacks. Conventional countermeasures, which jointly optimize the encoder and decoder via a noise layer, face 2 inevitable challenges:(1) decrease of cle

HiVid: LLM-Guided Video Saliency For Content-Aware VOD And Live Streaming

ICLR 2026poster

Content-aware streaming requires dynamic, chunk-level importance weights to optimize subjective quality of experience (QoE). However, direct human annotation is prohibitively expensive while vision-saliency models generalize poorly. We introduce HiVid, the first framework to leverage Large Language…

SpectraLLM: Uncovering the Ability of LLMs for Molecule Structure Elucidation from Multi-Spectra

ICLR 2026poster

Automated molecular structure elucidation remains challenging, as existing approaches often depend on pre-compiled databases or restrict themselves to single spectroscopic modalities. Here we introduce **SpectraLLM**, a large language model that performs end-to-end structure prediction by reasoning…

ViTok-v2: Scaling Native-Resolution Autoencoders to 5B

ICML 2026poster

Vision Transformer (ViT) tokenizers offer a scal- able alternative to convolutional auto-encoders, yet current architectures have two key limitations: their performance degrades when images vary in aspect ratio or resolution, and their reliance on adversarial losses makes them harder to train at sca…

3D Vision-tactile Reconstruction from Infrared and Visible Images for Robotic Fine-grained Tactile Perception

IROS 2025

To achieve human-like haptic perception in anthropomorphic grippers, the compliant sensing surfaces of vision tactile sensor (VTS) must evolve from conventional planar configurations to biomimetically curved topographies with continuous surface gradients. However, planar VTSs have challenges when ex

MTIL: Encoding Full History With Mamba for Temporal Imitation Learning

RA-L 2025

Standard imitation learning (IL) methods have achieved considerable success in robotics, yet often rely on the Markov assumption, which falters in long-horizon tasks where history is crucial for resolving perceptual ambiguity. This limitation stems not only from a conceptual gap but also from a fund

Towards Personalized Federated Learning via Contrastive-Augmented Local Memorization Retrieval

ICASSP 2025accepted

Federated learning (FL) enables clients to collaboratively train statistical models while maintaining the privacy of their local data. However, traditional FL methods often suffer performance degradation due to data heterogeneity across clients. To mitigate this issue, we propose an efficient person…

D3ETR: Decoder Distillation for Detection Transformer

IJCAI 2024poster

Although various knowledge distillation (KD) methods for CNN-based detectors have been proven effective in improving small students, build- ing baselines and recipes for DETR-based detec- tors remains a challenge. This paper concentrates on the transformer decoder of DETR-based detec- tors and explo…

Text-to-Sticker: Style Tailoring Latent Diffusion Models for Human Expression

ECCV 2024poster

"We introduce Style Tailoring, a recipe to finetune Latent Diffusion Models (LDMs) in a distinct domain with high visual quality, prompt alignment and scene diversity. We choose sticker image generation as the target domain, as the images significantly differ from photorealistic samples typically ge…

VRP-SAM: SAM with Visual Reference Prompt

CVPR 2024poster

In this paper we propose a novel Visual Reference Prompt (VRP) encoder that empowers the Segment Anything Model (SAM) to utilize annotated reference images as prompts for segmentation creating the VRP-SAM model. In essence VRP-SAM can utilize annotated reference images to comprehend specific objects…

Training Set Cleansing of Backdoor Poisoning by Self-Supervised Representation Learning

ICASSP 2023accepted

A backdoor or Trojan attack is an important type of data poisoning attack against deep neural network (DNN) classifiers, wherein the training dataset is poisoned with a small number of samples that each possess the backdoor pattern (usually a pattern that is either imperceptible or innocuous) and wh…

Graph-Enhanced Multi-Task Learning of Multi-Level Transition Dynamics for Session-based Recommendation

AAAI 2021technical

Session-based recommendation plays a central role in a wide spectrum of online applications, ranging from e-commerce to online advertising services. However, the majority of existing session-based recommendation techniques (e.g., attention-based recurrent network or graph neural network) are not wel…
