Rich Human Feedback for Text-to-Image Generation

1 code implementation15 Dec 2023 Youwei Liang, Junfeng He, Gang Li, Peizhao Li, Arseniy Klimovskiy, Nicholas Carolan, Jiao Sun, Jordi Pont-Tuset, Sarah Young, Feng Yang, Junjie Ke, Krishnamurthy Dj Dvijotham, Katie Collins, Yiwen Luo, Yang Li, Kai J Kohlhoff, Deepak Ramachandran, Vidhya Navalpakkam

We show that the predicted rich human feedback can be leveraged to improve image generation, for example, by selecting high-quality training data to finetune and improve the generative models, or by creating masks with predicted heatmaps to inpaint the problematic regions.

UniAR: Unifying Human Attention and Response Prediction on Visual Content

no code implementations15 Dec 2023 Peizhao Li, Junfeng He, Gang Li, Rachit Bhargava, Shaolei Shen, Nachiappan Valliappan, Youwei Liang, Hongxiang Gu, Venky Ramachandran, Golnaz Farhadi, Yang Li, Kai J Kohlhoff, Vidhya Navalpakkam

Such a model would enable predicting subjective feedback such as overall satisfaction or aesthetic quality ratings, along with the underlying human attention or interaction heatmaps and viewing order, enabling designers and content-creation models to optimize their creation for human-centric improvements.

Dual Node and Edge Fairness-Aware Graph Partition

no code implementations16 Jun 2023 TingWei Liu, Peizhao Li, Hongfu Liu

To address this gap, we propose a notion edge balance to measure the proportion of edges connecting different demographic groups in clusters.

Characterizing the Influence of Graph Elements

no code implementations14 Oct 2022 Zizhang Chen, Peizhao Li, Hongfu Liu, Pengyu Hong

To fill this gap, we started with the simple graph convolution (SGC) model that operates on an attributed graph and formulated an influence function to approximate the changes in model parameters when a node or an edge is removed from an attributed graph.

Robust Fair Clustering: A Novel Fairness Attack and Defense Framework

1 code implementation4 Oct 2022 Anshuman Chhabra, Peizhao Li, Prasant Mohapatra, Hongfu Liu

Experimentally, we observe that CFC is highly robust to the proposed attack and is thus a truly robust fair clustering alternative.

Achieving Fairness at No Utility Cost via Data Reweighing with Influence

1 code implementation1 Feb 2022 Peizhao Li, Hongfu Liu

With the fast development of algorithmic governance, fairness has become a compulsory property for machine learning models to suppress unintentional discrimination.

Code Editing from Few Exemplars by Adaptive Multi-Extent Composition

no code implementations29 Sep 2021 Peizhao Li, Xuchao Zhang, Ziyu Yao, Wei Cheng, Haifeng Chen, Hongfu Liu

To achieve this, we propose a machine learning approach to adapt the editorial style derived from few exemplars to a query code snippet.

Deep Clustering based Fair Outlier Detection

1 code implementation9 Jun 2021 Hanyu Song, Peizhao Li, Hongfu Liu

In this paper, we focus on the fairness issues regarding unsupervised outlier detection.

Deep Fair Clustering for Visual Learning

1 code implementation CVPR 2020 Peizhao Li, Han Zhao, Hongfu Liu

In light of these limitations, in this paper, we propose Deep Fair Clustering (DFC) to learn fair and clustering-favorable representations for clustering simultaneously.

Model-free Tracking with Deep Appearance and Motion Features Integration

no code implementations16 Dec 2018 Xiaolong Jiang, Peizhao Li, Xian-Tong Zhen, Xian-Bin Cao

To overcome the object-centric information scarcity, both appearance and motion features are deeply integrated by the proposed AMNet, which is an end-to-end offline trained two-stream network.
