Constructing vectorized high-definition maps from surround-view cameras has garnered significant attention in recent years.

U-Mamba: Enhancing Long-range Dependency for Biomedical Image Segmentation

no code implementations9 Jan 2024 Jun Ma, Feifei Li, Bo wang

Convolutional Neural Networks (CNNs) and Transformers have been the most popular architectures for biomedical image segmentation, but both of them have limited ability to handle long-range dependencies because of inherent locality or computational complexity.

CSCLog: A Component Subsequence Correlation-Aware Log Anomaly Detection Method

1 code implementation7 Jul 2023 Ling Chen, Chaodu Song, Xu Wang, Dachao Fu, Feifei Li

To this end, we propose CSCLog, a Component Subsequence Correlation-Aware Log anomaly detection method, which not only captures the sequential dependencies in subsequences, but also models the implicit correlations of subsequences.

Towards General Deep Leakage in Federated Learning

no code implementations18 Oct 2021 Jiahui Geng, Yongli Mou, Feifei Li, Qing Li, Oya Beyan, Stefan Decker, Chunming Rong

We find that image restoration fails even if there is only one incorrectly inferred label in the batch; we also find that when batch images have the same label, the corresponding image is restored as a fusion of that class of images.
