EdaDet: Open-Vocabulary Object Detection Using Early Dense Alignment

no code implementations ICCV 2023 Cheng Shi, Sibei Yang

Vision-language models such as CLIP have boosted the performance of open-vocabulary object detection, where the detector is trained on base categories but required to detect novel categories.

High-Rate Phase Association with Travel Time Neural Fields

1 code implementation14 Jul 2023 Cheng Shi, Maarten V. de Hoop, Ivan Dokmanić

Existing techniques relying on coarsely approximated, fixed wave speed models fail in this unexplored dense regime where the complexity of unknown wave speed cannot be ignored.

A Graph Dynamics Prior for Relational Inference

1 code implementation9 Jun 2023 Liming Pan, Cheng Shi, Ivan Dokmanić

In this work, we propose a \textit{graph dynamics prior} (GDP) for relational inference.

Homophily modulates double descent generalization in graph convolution networks

1 code implementation26 Dec 2022 Cheng Shi, Liming Pan, Hong Hu, Ivan Dokmanić

Motivated by experimental observations of ``transductive'' double descent in key networks and datasets, we use analytical tools from statistical physics and random matrix theory to precisely characterize generalization in simple graph convolution networks on the contextual stochastic block model.

Manifold Rewiring for Unlabeled Imaging

no code implementations12 Sep 2022 Valentin Debarnot, Vinith Kishore, Cheng Shi, Ivan Dokmanić

We illustrate our graph denoising framework on regular synthetic graphs and then apply it to single-particle cryo-EM where the measurements are corrupted by very high levels of noise.

Neural Link Prediction with Walk Pooling

1 code implementation ICLR 2022 Liming Pan, Cheng Shi, Ivan Dokmanić

Instead of extracting transition probabilities from the original graph, it computes the transition matrix of a "predictive" latent graph by applying attention to learned features; this may be interpreted as feature-sensitive topology fingerprinting.
