Alleviating Performance Degradation Caused by Out-of-Distribution Issues in Embedding-Based Retrieval

EMNLP 2025

In Embedding Based Retrieval (EBR), Approximate Nearest Neighbor (ANN) algorithms are widely adopted for efficient large-scale search. However, recent studies reveal a query out-of-distribution (OOD) issue, where query and base embeddings follow mismatched distributions, significantly degrading ANN

Split to Be Slim: An Overlooked Redundancy in Vanilla Convolution

IJCAI 2020poster

Many effective solutions have been proposed to reduce the redundancy of models for inference acceleration. Nevertheless, common approaches mostly focus on eliminating less important filters or constructing efficient operations, while ignoring the pattern redundancy in feature maps. We reveal that ma…

Automatic human fall detection in fractional fourier domain for assisted living

ICASSP 2016accepted

Fast and accurate detection of elderly falls can significantly reduce the rate of morbidity and mortality. In the past decade, extensive research has been performed to achieve real-time fall monitoring solutions. In this paper, we consider the radar-based modality and utilize the family of fractiona…
