A Causality-Aware Pattern Mining Scheme for Group Activity Recognition in a Pervasive Sensor Space

no code implementations1 Dec 2023 Hyunju Kim, Heesuk Son, Dongman Lee

In this paper, we focus on a group activity by which a group of users perform a collaborative task without user identification and propose an efficient group activity recognition scheme which extracts causality patterns from pervasive sensor event sequences generated by a group of users to support as good recognition accuracy as the state-of-the-art graphical model.

Beyond Entropy: Style Transfer Guided Single Image Continual Test-Time Adaptation

no code implementations30 Nov 2023 Younggeol Cho, Youngrae Kim, Dongman Lee

To overcome these challenges, we present BESTTA, a novel single image continual test-time adaptation method guided by style transfer, which enables stable and efficient adaptation to the target environment by transferring the style of the input image to the source style.
