LEXam: Benchmarking Legal Reasoning on 340 Law Exams

ICLR 2026poster

Long-form legal reasoning remains a key challenge for large language models (LLMs) in spite of recent advances in test-time scaling. To address this, we introduce ***LEXam***, a novel benchmark derived from 340 law exams spanning 116 law school courses across a range of subjects and degree levels. T…

Rethinking Time-Series Imputation as Conditional Inference along Temporal Evolution

ICML 2026poster

Real-world time-series data often suffer from missing observations, hindering long-range temporal modeling. However, most existing imputation methods formulate imputation as conditional reconstruction over limited context, which restricts temporal information propagation and fails to explicitly mode…

When AI Benchmarks Plateau: A Systematic Study of Benchmark Saturation

ICML 2026poster

Artificial Intelligence (AI) benchmarks play a central role in measuring progress in model development and guiding deployment decisions. However, many benchmarks quickly become saturated, meaning that they can no longer differentiate between the best-performing models, diminishing their long-term va…

MalDetectFormer: Leveraging Sparse SpatioTemporal Information for Effective Malicious Traffic Detection

AAAI 2025technical

Malicious traffic detection is one of the main challenges in the field of cybersecurity. Although modern deep learning methods have made progress in identifying malicious traffic, they often overlook the persistent nature of attack behaviors, making it difficult to distinguish between malicious and…

Medical Image Segmentation with Auxiliary Points Prediction of Lesion Location and Boundary

ICASSP 2025accepted

In order to obtain good medical image segmentation results, existing studies usually extract multi-scale features or design special attention to obtain global and local information of images. However, the above methods are very cumbersome or have a high computational burden. Theoretically, global an…

The Medium Is Not the Message: Deconfounding Document Embeddings via Linear Concept Erasure

EMNLP 2025

Embedding-based similarity metrics between text sequences can be influenced not just by the content dimensions we most care about, but can also be biased by spurious attributes like the text’s source or language. These document confounders cause problems for many applications, but especially those t

MetaER-TTE: An Adaptive Meta-learning Model for En Route Travel Time Estimation

IJCAI 2022poster

En route travel time estimation (ER-TTE) aims to predict the travel time on the remaining route. Since the traveled and remaining parts of a trip usually have some common characteristics like driving speed, it is desirable to explore these characteristics for improved performance via effective adapt…

Just Noticeable Difference Model for Asymmetrically Distorted Stereoscopic Images

ICASSP 2019accepted

In this paper, we propose a saliency-weighted stereoscopic JND (SSJND) model constructed based on psychophysical experiments, accounting for binocular disparity and spatial masking effects of the human visual system (HVS). Specifically, a disparity-aware binocular JND model is first developed using…

Stereoscopic image quality assessment based on the binocular properties of the human visual system

ICASSP 2017accepted

One of the most challenging issues in stereoscopic image quality assessment (IQA) is how to effectively model the binocular behaviors of the human visual system (HVS). The latter has a great impact on the perceptual stereoscopic 3D (S3D) quality. This paper presents a stereoscopic IQA metric based o…
