Enhancing Conversational Recommender Systems with Tree-Structured Knowledge and Pretrained Language Models

AAAI 2026technical

Recent advances in pretrained language models (PLMs) have significantly improved conversational recommender systems (CRS), enabling more fluent and context-aware interactions. To further enhance accuracy and mitigate hallucination, many methods integrate PLMs with knowledge graphs (KGs), but face ke

Diffusion Transformer meets Multi-level Wavelet Spectrum for Single Image Super-Resolution

ICCV 2025poster

Discrete Wavelet Transform (DWT) has been widely explored to enhance the performance of image super-resolution (SR). Despite some DWT-based methods improving SR by capturing fine-grained frequency signals, most existing approaches neglect the interrelations among multi-scale frequency sub-bands, res…

3D Automated Quantitative Calculations Based on CT Images of the Hip Joint

ICASSP 2024accepted

This paper presents a geometric model for achieving automatic 3D quantitative calculation of the femoroacetabular impingement (FAI) index on computed tomography (CT) images. The result is then used in subsequent work to reduce errors due to perspective differences in existing clinical measurements.…

Geometric Structure Preserving Warp for Natural Image Stitching

CVPR 2022poster

Preserving geometric structures in the scene plays a vital role in image stitching. However, most of the existing methods ignore the large-scale layouts reflected by straight lines or curves, decreasing overall stitching quality. To address this issue, this work presents a structure-preserving stitc…

iNAS: Integral NAS for Device-Aware Salient Object Detection

ICCV 2021poster

Existing salient object detection (SOD) models usually focus on either backbone feature extractors or saliency heads, ignoring their relations. A powerful backbone could still achieve sub-optimal performance with a weak saliency head and vice versa. Moreover, the balance between model performance an…
