Event-based multimodal large language models (MLLMs) enable robust perception in high-speed and low-light scenarios, addressing key limitations of frame-based MLLMs. However, current event-based MLLMs often rely on dense image-like processing paradigms, overlooking the spatiotemporal sparsity of eve…
Low-rank approximation has emerged as a cornerstone technique for model compression and parameter-efficient fine-tuning, enabling substantial reductions in computation and memory without altering model architectures.

Depth-wise pruning accelerates LLM inference in resource-constrained scenarios but suffers from performance degradation due to indiscriminate removal of entire Transformer layers. This paper reveals ``Patch-Like
Time-frequency analysis (TFA) and mode decomposition for non-stationary signals are research hotspots in the field of signal processing. Current optimization-based decomposition methods require a good initial IF estimate. However, due to the Heisenberg uncertainty, achieving accurate ridge extractio
Conventional frame-based imaging for active stereo systems has encountered major challenges in fast-motion scenarios.

Lane detection plays a critical role in autonomous driving, requiring low-latency response and robustness to varying lighting conditions to support downstream algorithms effectively. Event cameras, with their low latency and high dynamic range, are well-suited for such tasks. However, current event-
Accurate stereo matching under fast motion and extreme lighting conditions is a challenge for many vision applications. Event cameras have the advantages of low latency and high dynamic range, thus providing a reliable solution to this challenge. However, since events are sparse, this makes it an il…
Event cameras capture visual information as asynchronous pixel change streams, excelling in challenging lighting and high-dynamic scenarios.

Large Language Models (LLMs) are prone to hallucinations, which pose significant risks in their applications. Most existing hallucination detection methods rely on internal probabilities or external knowledge, and they are limited to identifying hallucinations at the sentence or passage level. In th…
Human keypoint detection is fundamental in computer vision, with applications in pose estimation and action recognition.

Neural networks are widely used in various NLP tasks for their remarkable performance. However, the complexity makes them difficult to interpret, i.e., they are not guaranteed right for the right reason. Besides the complexity, we reveal that the model pathology - the inconsistency between word sali…
Neural networks are vulnerable to adversarial examples. The adversary can successfully attack a model even without knowing model architecture and parameters, i.e., under a black-box scenario.
