Attention-based Deep Reinforcement Learning for Multi-view Environments

no code implementations10 May 2019 Elaheh Barati, Xue-wen Chen, Zichun Zhong

In reinforcement learning algorithms, it is a common practice to account for only a single view of the environment to make the desired decisions; however, utilizing multiple views of the environment can help to promote the learning of complicated policies.

Optimizing Taxi Carpool Policies via Reinforcement Learning and Spatio-Temporal Mining

no code implementations11 Nov 2018 Ishan Jindal, Zhiwei Qin, Xue-wen Chen, Matthew Nokleby, Jieping Ye

In this paper, we develop a reinforcement learning (RL) based system to learn an effective policy for carpooling that maximizes transportation efficiency so that fewer cars are required to fulfill the given amount of trip demand.

An Adaptive Cluster-based Filtering Framework for Speckle Reduction of OCT Skin Images

no code implementations31 Jul 2017 Elaheh Rashedi, Saba Adabi, Darius Mehregan, Silvia Conforto, Xue-wen Chen

The proposed cluster-based filtering framework enables researchers to develop unsupervised learning solutions for de-speckling OCT skin images using adaptive filtering methods, or extend the framework to new applications.

Large-scale Datasets: Faces with Partial Occlusions and Pose Variations in the Wild

no code implementations27 Jun 2017 Tarik Alafif, Zeyad Hailat, Melih Aslan, Xue-wen Chen

The LSLF dataset is currently the largest labeled face image dataset in the literature in terms of the number of labeled images and the number of individuals compared to other existing labeled face image datasets.

Learning Deep Networks from Noisy Labels with Dropout Regularization

no code implementations9 May 2017 Ishan Jindal, Matthew Nokleby, Xue-wen Chen

Large datasets often have unreliable labels-such as those obtained from Amazon's Mechanical Turk or social media platforms-and classifiers trained on mislabeled datasets often exhibit poor performance.
