A Unified Framework for Connecting Noise Modeling to Boost Noise Detection

1 code implementation30 Nov 2023 Siqi Wang, Chau Pham, Bryan A. Plummer

In this work, we explore the integration of these two approaches, proposing an interconnected structure with three crucial blocks: noise modeling, source knowledge identification, and enhanced noise detection using noise source-knowledge-integration methods.

MixtureGrowth: Growing Neural Networks by Recombining Learned Parameters

1 code implementation7 Nov 2023 Chau Pham, Piotr Teterwak, Soren Nelson, Bryan A. Plummer

Newly grown layer weights are generated by using a new linear combination of existing templates for a layer.

CHAMMI: A benchmark for channel-adaptive models in microscopy imaging

2 code implementations NeurIPS 2023 Zitong Chen, Chau Pham, Siqi Wang, Michael Doron, Nikita Moshkov, Bryan A. Plummer, Juan C. Caicedo

In this paper, we present a benchmark for investigating channel-adaptive models in microscopy imaging, which consists of 1) a dataset of varied-channel single-cell images, and 2) a biologically relevant evaluation framework.

LP-OVOD: Open-Vocabulary Object Detection by Linear Probing

1 code implementation26 Oct 2023 Chau Pham, Truong Vu, Khoi Nguyen

To address this issue, we propose a novel method, LP-OVOD, that discards low-quality boxes by training a sigmoid linear classifier on pseudo labels retrieved from the top relevant region proposals to the novel text.

Let Models Speak Ciphers: Multiagent Debate through Embeddings

no code implementations10 Oct 2023 Chau Pham, Boyi Liu, Yingxiang Yang, Zhengyu Chen, Tianyi Liu, Jianbo Yuan, Bryan A. Plummer, Zhaoran Wang, Hongxia Yang

Although natural language is an obvious choice for communication due to LLM's language understanding capability, the token sampling step needed when generating natural language poses a potential risk of information loss, as it uses only one token to represent the model's belief across the entire vocabulary.

Deep Distance Sensitivity Oracles

no code implementations2 Nov 2022 Davin Jeong, Allison Gunby-Mann, Sarel Cohen, Maximilian Katzmann, Chau Pham, Arnav Bhakta, Tobias Friedrich, Sang Chin

More specifically, we utilize the combinatorial structure of replacement paths as a concatenation of shortest paths and use deep learning to find the pivot nodes for stitching shortest paths into replacement paths.

A Multi-scale Graph Signature for Persistence Diagrams based on Return Probabilities of Random Walks

no code implementations28 Sep 2022 Chau Pham, Trung Dang, Peter Chin

Persistence diagrams (PDs), often characterized as sets of death and birth of homology class, have been known for providing a topological representation of a graph structure, which is often useful in machine learning tasks.

Emotion analysis and detection during COVID-19

no code implementations LREC 2022 Tiberiu Sosea, Chau Pham, Alexander Tekle, Cornelia Caragea, Junyi Jessy Li

Crises such as natural disasters, global pandemics, and social unrest continuously threaten our world and emotionally affect millions of people worldwide in distinct ways.

Road Damage Detection and Classification with Detectron2 and Faster R-CNN

1 code implementation28 Oct 2020 Vung Pham, Chau Pham, Tommy Dang

The results show that the X101-FPN base model for Faster R-CNN with Detectron2's default configurations are efficient and general enough to be transferable to different countries in this challenge.
