Data-Effective Learning: A Comprehensive Medical Benchmark

1 code implementation31 Jan 2024 Wenxuan Yang, Weimin Tan, Yuqi Sun, Bo Yan

This benchmark includes a dataset with millions of data samples from 31 medical centers (DataDEL), a baseline method for comparison (MedDEL), and a new evaluation metric (NormDEL) to objectively measure data-effective learning performance.

Low-latency Space-time Supersampling for Real-time Rendering

1 code implementation18 Dec 2023 Ruian He, Shili Zhou, Yuqi Sun, Ri Cheng, Weimin Tan, Bo Yan

With the rise of real-time rendering and the evolution of display devices, there is a growing demand for post-processing methods that offer high-resolution content in a high frame rate.

Instruct-NeuralTalker: Editing Audio-Driven Talking Radiance Fields with Instructions

no code implementations19 Jun 2023 Yuqi Sun, Ruian He, Weimin Tan, Bo Yan

Given a short speech video, we first build an efficient talking radiance field, and then apply the latest conditional diffusion model for image editing based on the given instructions and guiding implicit representation optimization towards the editing target.

Geometry-Aware Reference Synthesis for Multi-View Image Super-Resolution

no code implementations18 Jul 2022 Ri Cheng, Yuqi Sun, Bo Yan, Weimin Tan, Chenxi Ma

To address these problems, we propose the MVSRnet, which uses geometry information to extract sharp details from all LR multi-view to support the SR of the LR input view.

Learning Robust Image-Based Rendering on Sparse Scene Geometry via Depth Completion

no code implementations CVPR 2022 Yuqi Sun, Shili Zhou, Ri Cheng, Weimin Tan, Bo Yan, Lang Fu

Specifically, GR stage takes sparse depth map and RGB as input to predict dense depth map by exploiting the correlation between two modals.

Multiple imputation using chained random forests: a preliminary study based on the empirical distribution of out-of-bag prediction errors

1 code implementation30 Apr 2020 Shangzhi Hong, Yuqi Sun, Hanying Li, Henry S. Lynn

In this study, a novel RF-based multiple imputation method was proposed by constructing conditional distributions the empirical distribution of out-of-bag prediction errors.

Influence of parallel computing strategies of iterative imputation of missing data: a case study on missForest

1 code implementation23 Apr 2020 Shangzhi Hong, Yuqi Sun, Hanying Li, Henry S. Lynn

Machine learning iterative imputation methods have been well accepted by researchers for imputing missing data, but they can be time-consuming when handling large datasets.

Implicit Subjective and Sentimental Usages in Multi-sense Word Embeddings

no code implementations WS 2018 Yuqi Sun, Haoyue Shi, Junfeng Hu

In multi-sense word embeddings, contextual variations in corpus may cause a univocal word to be embedded into different sense vectors.

Understanding and Improving Multi-Sense Word Embeddings via Extended Robust Principal Component Analysis

no code implementations3 Mar 2018 Haoyue Shi, Yuqi Sun, Junfeng Hu

Unsupervised learned representations of polysemous words generate a large of pseudo multi senses since unsupervised methods are overly sensitive to contextual variations.

Learning Rich Geographical Representations: Predicting Colorectal Cancer Survival in the State of Iowa

no code implementations15 Aug 2017 Michael T. Lash, Yuqi Sun, Xun Zhou, Charles F. Lynch, W. Nick Street

Specifically, we compare model performance using a newly defined metric -- area between the curves (ABC) -- to assess (a) whether survival curves can be reasonably predicted for colorectal cancer patients in the state of Iowa, (b) whether geographical features improve predictive performance, and (c) whether a simple binary representation or richer, spectral clustering-based representation perform better.
