GPGS: Geometric Priors for 3D Gaussian Splatting in Structural Environments

IROS 2025

Recently, 3D Gaussian Splatting (3DGS) has garnered significant attention for its remarkable capacity to efficiently synthesize novel views with high fidelity. Nevertheless, 3DGS encounters challenges in accurately representing the geometry of real-world scenes. To address this issue, previous metho

Bilateral Adaptation for Human-Object Interaction Detection with Occlusion-Robustness

CVPR 2024poster

Human-Object Interaction (HOI) Detection constitutes an important aspect of human-centric scene understanding which requires precise object detection and interaction recognition. Despite increasing advancement in detection recognizing subtle and intricate interactions remains challenging. Recent met…

Don't Pour Cereal into Coffee: Differentiable Temporal Logic for Temporal Action Segmentation

NeurIPS 2022accept

We propose Differentiable Temporal Logic (DTL), a model-agnostic framework that introduces temporal constraints to deep networks. DTL treats the outputs of a network as a truth assignment of a temporal logic formula, and computes a temporal logic loss reflecting the consistency between the output an…

Unsupervised Motion Representation Learning with Capsule Autoencoders

NeurIPS 2021poster

We propose the Motion Capsule Autoencoder (MCAE), which addresses a key challenge in the unsupervised learning of motion representations: transformation invariance. MCAE models motion in a two-level hierarchy. In the lower level, a spatio-temporal motion signal is divided into short, local, and sema…

Embedding Symbolic Knowledge into Deep Networks

NeurIPS 2019poster

In this work, we aim to leverage prior symbolic knowledge to improve the performance of deep models. We propose a graph embedding network that projects propositional formulae (and assignments) onto a manifold via an augmented Graph Convolutional Network (GCN). To generate semantically-faithful embed…

Decentralized motion planning with collision avoidance for a team of UAVs under high level goals

ICRA 2017poster

This paper addresses the motion planning problem for a team of aerial agents under high level goals. We propose a hybrid control strategy that guarantees the accomplishment of each agent's local goal specification, which is given as a temporal logic formula, while guaranteeing inter-agent collision…
