Dual Advancement of Representation Learning and Clustering for Sparse and Noisy Images

1 code implementation3 Sep 2024 Wenlin Li, Yucheng Xu, Xiaoqing Zheng, Suoya Han, Jun Wang, Xiaobo Sun

Sparse and noisy images (SNIs), like those in spatial gene expression data, pose significant challenges for effective representation learning and clustering, which are essential for thorough data analysis and interpretation.

3D Feature Distillation with Object-Centric Priors

no code implementations26 Jun 2024 Georgios Tziafas, Yucheng Xu, Zhibin Li, Hamidreza Kasaei

In this work, we show that this approach leads to sub-optimal 3D features, both in terms of grounding accuracy, as well as segmentation crispness.

Language-guided Robot Grasping: CLIP-based Referring Grasp Synthesis in Clutter

1 code implementation9 Nov 2023 Georgios Tziafas, Yucheng Xu, Arushi Goel, Mohammadreza Kasaei, Zhibin Li, Hamidreza Kasaei

To address these limitations, we develop a challenging benchmark based on cluttered indoor scenes from OCID dataset, for which we generate referring expressions and connect them with 4-DoF grasp poses.
