How Powerful Potential of Attention on Image Restoration?

no code implementations15 Mar 2024 Cong Wang, Jinshan Pan, Yeying Jin, Liyan Wang, Wei Wang, Gang Fu, Wenqi Ren, Xiaochun Cao

Our designs provide a closer look at the attention mechanism and reveal that some simple operations can significantly affect the model performance.

Learning from Aggregate responses: Instance Level versus Bag Level Loss Functions

no code implementations20 Jan 2024 Adel Javanmard, Lin Chen, Vahab Mirrokni, Ashwinkumar Badanidiyuru, Gang Fu

In this paper, we study two natural loss functions for learning from aggregate responses: bag-level loss and the instance-level loss.

Greedy PIG: Adaptive Integrated Gradients

no code implementations10 Nov 2023 Kyriakos Axiotis, Sami Abu-al-haija, Lin Chen, Matthew Fahrbach, Gang Fu

We demonstrate the success of Greedy PIG on a wide variety of tasks, including image feature attribution, graph compression/explanation, and post-hoc feature selection on tabular data.

Learning from Aggregated Data: Curated Bags versus Random Bags

no code implementations16 May 2023 Lin Chen, Gang Fu, Amin Karbasi, Vahab Mirrokni

Our method is based on the observation that the sum of the gradients of the loss function on individual data examples in a curated bag can be computed from the aggregate label without the need for individual labels.

Approximately Optimal Core Shapes for Tensor Decompositions

no code implementations8 Feb 2023 Mehrdad Ghadiri, Matthew Fahrbach, Gang Fu, Vahab Mirrokni

This work studies the combinatorial optimization problem of finding an optimal core tensor shape, also called multilinear rank, for a size-constrained Tucker decomposition.

Sequential Attention for Feature Selection

1 code implementation29 Sep 2022 Taisuke Yasuda, Mohammadhossein Bateni, Lin Chen, Matthew Fahrbach, Gang Fu, Vahab Mirrokni

Feature selection is the problem of selecting a subset of features for a machine learning model that maximizes model quality subject to a budget constraint.

Deep Image-based Illumination Harmonization

no code implementations CVPR 2022 Zhongyun Bao, Chengjiang Long, Gang Fu, Daquan Liu, Yuanzhen Li, Jiaming Wu, Chunxia Xiao

Specifically, we firstly apply a physically-based rendering method to construct a large-scale, high-quality dataset (named IH) for our task, which contains various types of foreground objects and background scenes with different lighting conditions.

Feature Cross Search via Submodular Optimization

no code implementations5 Jul 2021 Lin Chen, Hossein Esfandiari, Gang Fu, Vahab S. Mirrokni, Qian Yu

First, we show that it is not possible to provide an $n^{1/\log\log n}$-approximation algorithm for this problem unless the exponential time hypothesis fails.

CRPN-SFNet: A High-Performance Object Detector on Large-Scale Remote Sensing Images

no code implementations28 Oct 2020 QiFeng Lin, Jianhui Zhao, Gang Fu, and Zhiyong Yuan, Member, IEEE

Extensive experiments on the public Dataset for Object deTection in Aerial images data set indicate that our CRPN can help our detector deal the larger image faster with the limited GPU memory; meanwhile, the SFNet is beneficial to achieve more accurate detection of geospatial objects with wide-scale range.

On Reasoning with RDF Statements about Statements using Singleton Property Triples

no code implementations15 Sep 2015 Vinh Nguyen, Olivier Bodenreider, Krishnaprasad Thirunarayan, Gang Fu, Evan Bolton, Núria Queralt Rosinach, Laura I. Furlong, Michel Dumontier, Amit Sheth

If the singleton property triples describe a data triple, then how can a reasoner infer this data triple from the singleton property triples?
