PolyDiffuse: Polygonal Shape Reconstruction via Guided Set Diffusion Models

NeurIPS 2023poster

This paper presents \textit{PolyDiffuse}, a novel structured reconstruction algorithm that transforms visual sensor data into polygonal shapes with Diffusion Models (DM), an emerging machinery amid exploding generative AI, while formulating reconstruction as a generation process conditioned on senso…

Modeling Continuous Stochastic Processes with Dynamic Normalizing Flows

NeurIPS 2020poster

Normalizing flows transform a simple base distribution into a complex target distribution and have proved to be powerful models for data generation and density estimation. In this work, we propose a novel type of normalizing flow driven by a differential deformation of the continuous-time Wiener pro…

AdvIT: Adversarial Frames Identifier Based on Temporal Consistency in Videos

ICCV 2019poster

Deep neural networks (DNNs) have been widely applied in various applications, including autonomous driving and surveillance systems. However, DNNs are found to be vulnerable to adversarial examples, which are carefully crafted inputs aiming to mislead a learner to make incorrect predictions. While s…

Characterizing Adversarial Examples Based on Spatial Consistency Information for Semantic Segmentation

ECCV 2018poster

Deep Neural Networks (DNNs) have been widely applied in various recognition tasks. However, recently DNNs have been shown to be vulnerable against adversarial examples, which can mislead DNNs to make arbitrary incorrect predictions. While adversarial examples are mainly studied in classification, sp…

Sparsely Aggregated Convolutional Networks

ECCV 2018poster

We explore a key architectural aspect of deep convolutional neural networks: the pattern of internal skip connections used to aggregate outputs of earlier layers for consumption by deeper layers. Such aggregation is critical to facilitate training of very deep networks in an end-to-end manner. This…
