A Consistency-Improved LiDAR-Inertial Bundle Adjustment

RA-L 2026

Simultaneous Localization and Mapping (SLAM) using 3D LiDAR has emerged as a cornerstone for autonomous navigation in robotics. While feature-based SLAM systems have achieved impressive results by leveraging edge and planar structures, they often suffer from the inconsistent estimator associated wit

Cooperative Graph Transformer with Structural Consensus for Multi-View Learning

AAAI 2026technical

Multi-view learning aims to effectively integrate data from different sources by exploring the consistency and complementarity across views. Current multi-view methods based on Graph Convolutional Networks (GCNs) primarily focus on local information, making it difficult to capture global dependencie

DG-ACMP: Deformation-Guided Motion Planning With Acceptable Contacts for Manipulators in Cluttered Environments

RA-L 2026

In cluttered environments where rigid and deformable objects coexist, collision-free paths often do not exist. Planners that enforce collision-free trajectories therefore perform poorly by excluding feasible contact-aware trajectories. We introduce the deformation-guided acceptable-contact motion pl

Don't Forget Its Variance! The Minimum Path Variance Principle for Accurate and Stable Score-Based Models

ICLR 2026poster

Score-based methods are powerful across machine learning, but they face a paradox: theoretically path-independent, yet practically path-dependent. We resolve this by proving that practical training objectives differ from the ideal, ground-truth objective by a crucial, overlooked term: the path var…

From Winning to Understanding: A Diagnostic Long-Horizon RTS Benchmark for LLMs

ICML 2026poster

Large language models (LLMs) are increasingly used as decision modules, yet existing benchmarks provide limited coverage of long-horizon, adversarial interaction while faithfully acting on human instructions. We introduce a long-horizon Red Alert RTS benchmark with a hierarchical interface in which …

Inductive Generative Recommendation via Retrieval-based Speculation

AAAI 2026technical

Generative recommendation (GR) is an emerging paradigm that tokenizes items into discrete tokens and learns to autoregressively generate the next tokens as predictions. While this token-generation paradigm is expected to surpass traditional transductive methods, potentially generating new items dire

RepSpec: Structural Re-parameterized Draft Model Training for Speculative Decoding

ICLR 2026poster

As the parameter size of large language models (LLMs) continues to grow, the latency of autoregressive inference increases due to memory-bound computational inefficiency. To address this, speculative decoding has been proposed, where a large target model verifies multiple tokens generated in paralle…

An Empirical Study of Position Bias in Modern Information Retrieval

EMNLP 2025

This study investigates the position bias in information retrieval, where models tend to overemphasize content at the beginning of passages while neglecting semantically relevant information that appears later. To analyze the extent and impact of position bias, we introduce a new evaluation framewor

Dequantified Diffusion-Schrödinger Bridge for Density Ratio Estimation

ICML 2025poster

Density ratio estimation is fundamental to tasks involving f-divergences, yet existing methods often fail under significantly different distributions or inadequately overlapping supports --- the density-chasm and the support-chasm problems. Additionally, prior approaches yield divergent time scores…

Learning Gain Map for Inverse Tone Mapping

ICLR 2025poster

For a more compatible and consistent high dynamic range (HDR) viewing experience, a new image format with a double-layer structure has been developed recently, which incorporates an auxiliary Gain Map (GM) within a standard dynamic range (SDR) image for adaptive HDR display. This new format motivate…

Seg2Any: Open-set Segmentation-Mask-to-Image Generation with Precise Shape and Semantic Control

NeurIPS 2025poster

Despite recent advances in diffusion models, top-tier text-to-image (T2I) models still struggle to achieve precise spatial layout control, *i.e.* accurately generating entities with specified attributes and locations. Segmentation-mask-to-image (S2I) generation has emerged as a promising solution by…

Effective passive membership inference attacks in federated learning against overparameterized models

ICLR 2023poster

This work considers the challenge of performing membership inference attacks in a federated learning setting ---for image classification--- where an adversary can only observe the communication between the central node and a single client (a passive white-box attack). Passive attacks are one of the…

Learning Steerable Function for Efficient Image Resampling

CVPR 2023poster

Image resampling is a basic technique that is widely employed in daily applications. Existing deep neural networks (DNNs) have made impressive progress in resampling performance. Yet these methods are still not the perfect substitute for interpolation, due to the issues of efficiency and continuous…

Open-world Semi-supervised Generalized Relation Discovery Aligned in a Real-world Setting

EMNLP 2023long main

Open-world Relation Extraction (OpenRE) has recently garnered significant attention. However, existing approaches tend to oversimplify the problem by assuming that all instances of unlabeled data belong to novel classes, thereby limiting the practicality of these methods. We argue that the OpenRE se…

PrimeNet: Pre-training for Irregular Multivariate Time Series

AAAI 2023technical

Real-world applications often involve irregular time series, for which the time intervals between successive observations are non-uniform. Irregularity across multiple features in a multi-variate time series further results in a different subset of features at any given time (i.e., asynchronicity).…

Robust Safe Learning and Control in an Unknown Environment: An Uncertainty-Separated Control Barrier Function Approach

RA-L 2023

A main challenge restricting the application of control barrier functions (CBFs) to complex scenarios is the absence of robustness against uncertainties induced by both measurements of the environment and robot dynamics. In this letter, we propose an uncertainty-aware, learning-based approach to con

SmartBERT: A Promotion of Dynamic Early Exiting Mechanism for Accelerating BERT Inference

IJCAI 2023poster

Dynamic early exiting has been proven to improve the inference speed of the pre-trained language model like BERT. However, all samples must go through all consecutive layers before early exiting and more complex samples usually go through more layers, which still exists redundant computation. In thi…

Existing semantic segmentation methods improve generalization capability, by regularizing various images to a canonical feature space. While this process contributes to generalization, it weakens the representation inevitably. In contrast to existing methods, we instead utilize the difference betwee…
