Aspect-Based Sentiment Analysis with Syntax-Opinion-Sentiment Reasoning Chain

COLING 2025main

Despite the impressive capabilities of large language models (LLMs) in aspect-based sentiment analysis (ABSA), the role of syntactic information remains underexplored in LLMs. Syntactic structures are known to be crucial for capturing aspect-opinion relationships. To explore whether LLMs can effecti…

TRACE: A Robust Framework for Malicious Traffic Detection with Noisy Labels

ICASSP 2025accepted

Deep learning-based malicious traffic detection requires large-scale, accurately labeled datasets. However, realistic malicious traffic datasets contain noisy labels due to annotation errors, which can degrade the performance of detection models. Existing methods for handling noisy labels involve ro…

Hidden Follower Detection: How Is the Gaze-Spacing Pattern Embodied in Frequency Domain?

AAAI 2024technical

Spatiotemporal social behavior analysis is a technique that studies the social behavior patterns of objects and estimates their risks based on their trajectories. In social public scenarios such as train stations, hidden following behavior has become one of the most challenging issues due to its pro…

Multimodal Evolutionary Encoder for Continuous Vision-Language Navigation

IROS 2024poster

Can multimodal encoder evolve when facing increasingly tough circumstances? Our work investigates this possibility in the context of continuous vision-language navigation (continuous VLN), which aims to navigate robots under linguistic supervision and visual feedback. We propose a multimodal evoluti…

Polynomial Width is Sufficient for Set Representation with High-dimensional Features

ICLR 2024poster

Set representation has become ubiquitous in deep learning for modeling the inductive bias of neural networks that are insensitive to the input order. DeepSets is the most widely used neural network architecture for set representation. It involves embedding each set element into a latent space with d…

FDLNet: Boosting Real-time Semantic Segmentation by Image-size Convolution via Frequency Domain Learning

ICRA 2023poster

This paper proposes a novel real-time semantic segmentation network via frequency domain learning, called FDLNet, which revisits the segmentation task from two critical perspectives: spatial structure description and multilevel feature fusion. We first devise an image-size convolution (IS-Conv) as a…

HoloSeg: An Efficient Holographic Segmentation Network for Real-time Scene Parsing

ICRA 2022poster

Real-time semantic segmentation is a crucial but challenging dense prediction task for scene parsing. However, the existing CNN-based methods commonly bias the model in favor of speed-boosting compromising spatial resolution due to business requirements and hardware constrains, which impedes the hig…

Velocity Following Control of a Pseudo-Driven Wheel for Reducing Internal Forces Between Wheels

RA-L 2022

The coordination of multiple driving wheels is an important issue in wheeled mobile robot design, for both maximizing tractive capability and optimizing energy consumption. This study converts a driving wheel into a pseudo-driven wheel (PDW), which is controlled to follow the motion of the robot bod
