Neural-Augmented Kelvinlet for Real-Time Soft Tissue Deformation Modeling

AAAI 2026technical

Accurate and efficient modeling of soft-tissue interactions is fundamental for advancing surgical simulation, surgical robotics, and model-based surgical automation. To achieve real-time latency, classical Finite Element Method (FEM) solvers are often replaced with neural approximations; however, na

Adversarial Learning Under Hybrid Perturbations for Robust Acute Lymphoblastic Leukemia Classification

AAAI 2025technical

Acute lymphoblastic leukemia is a childhood cancer prevalent worldwide, which can prove fatal within weeks or months. However, current diagnosis models based on machine learning and deep learning methods fail to consider device noise (pixel-level perturbations) and rotation/translation (spatial-tran…

TopoPoint: Enhance Topology Reasoning via Endpoint Detection in Autonomous Driving

NeurIPS 2025poster

Topology reasoning, which unifies perception and structured reasoning, plays a vital role in understanding intersections for autonomous driving. However, its performance heavily relies on the accuracy of lane detection, particularly at connected lane endpoints. Existing methods often suffer from lan…

Rethinking Boundary Discontinuity Problem for Oriented Object Detection

CVPR 2024poster

Oriented object detection has been developed rapidly in the past few years where rotation equivariance is crucial for detectors to predict rotated boxes. It is expected that the prediction can maintain the corresponding rotation when objects rotate but severe mutation in angular prediction is someti…

TopoLogic: An Interpretable Pipeline for Lane Topology Reasoning on Driving Scenes

NeurIPS 2024poster

As an emerging task that integrates perception and reasoning, topology reasoning in autonomous driving scenes has recently garnered widespread attention. However, existing work often emphasizes "perception over reasoning": they typically boost reasoning performance by enhancing the perception of la…

Gaussian Label Distribution Learning for Spherical Image Object Detection

CVPR 2023poster

Spherical image object detection emerges in many applications from virtual reality to robotics and automatic driving, while many existing detectors use ln-norms loss for regression of spherical bounding boxes. There are two intrinsic flaws for ln-norms loss, i.e., independent optimization of paramet…

Sph2Pob: Boosting Object Detection on Spherical Images with Planar Oriented Boxes Methods

IJCAI 2023poster

Object detection on panoramic/spherical images has been developed rapidly in the past few years, where IoU-calculator is a fundamental part of various detector components, i.e. Label Assignment, Loss and NMS. Due to the low efficiency and non-differentiability of spherical Unbiased IoU, spherical ap…

Identifying Corporate Credit Risk Sentiments from Financial News

NAACL 2022industry

Credit risk management is one central practice for financial institutions, and such practice helps them measure and understand the inherent risk within their portfolios. Historically, firms relied on the assessment of default probabilities and used the press as one tool to gather insights on the lat…
