Locally temporal-spatial pattern learning with graph attention mechanism for EEG-based emotion recognition

no code implementations19 Aug 2022 Yiwen Zhu, Kaiyu Gan, Zhong Yin

In the LTS-GAT, a divide-and-conquer scheme was used to examine local information on temporal and spatial dimensions of EEG patterns based on the graph attention mechanism.

Homotopy Based Reinforcement Learning with Maximum Entropy for Autonomous Air Combat

no code implementations1 Dec 2021 Yiwen Zhu, Zhou Fang, Yuan Zheng, Wenya Wei

In this paper, we propose a homotopy-based soft actor-critic method (HSAC) which focuses on addressing these problems via following the homotopy path between the original task with sparse reward and the auxiliary task with artificial prior experience reward.

Vamsa: Automated Provenance Tracking in Data Science Scripts

no code implementations7 Jan 2020 Mohammad Hossein Namaki, Avrilia Floratou, Fotis Psallidas, Subru Krishnan, Ashvin Agrawal, Yinghui Wu, Yiwen Zhu, Markus Weimer

There has recently been a lot of ongoing research in the areas of fairness, bias and explainability of machine learning (ML) models due to the self-evident or regulatory requirements of various ML applications.

Data Science through the looking glass and what we found there

no code implementations19 Dec 2019 Fotis Psallidas, Yiwen Zhu, Bojan Karlas, Matteo Interlandi, Avrilia Floratou, Konstantinos Karanasos, Wentao Wu, Ce Zhang, Subru Krishnan, Carlo Curino, Markus Weimer

The recent success of machine learning (ML) has led to an explosive growth both in terms of new systems and algorithms built in industry and academia, and new applications built by an ever-growing community of data science (DS) practitioners.

Griffon: Reasoning about Job Anomalies with Unlabeled Data in Cloud-based Platforms

no code implementations23 Aug 2019 Liqun Shao, Yiwen Zhu, Abhiram Eswaran, Kristin Lieber, Janhavi Mahajan, Minsoo Thigpen, Sudhir Darbha, SiQi Liu, Subru Krishnan, Soundar Srinivasan, Carlo Curino, Konstantinos Karanasos

In contrast, in Griffin we cast the problem to a corresponding regression one that predicts the runtime of a job, and show how the relative contributions of the features used to train our interpretable model can be exploited to rank the potential causes of job slowdowns.
