Responsive Regulation of Dynamic UAV Communication Networks Based on Deep Reinforcement Learning

no code implementations25 Aug 2021 Ran Zhang, Duc Minh, Nguyen, Miao Wang, Lin X. Cai, Xuemin, Shen

In this chapter, the regulation of Unmanned Aerial Vehicle (UAV) communication network is investigated in the presence of dynamic changes in the UAV lineup and user distribution.

A Simulated Experiment to Explore Robotic Dialogue Strategies for People with Dementia

no code implementations18 Apr 2021 Fengpei Yuan, Amir Sadovnik, Ran Zhang, Devin Casenhiser, Eun Jin Paek, Si On Yoon, Xiaopeng Zhao

People with Alzheimer's disease and related dementias (ADRD) often show the problem of repetitive questioning, which brings a great burden on persons with ADRD (PwDs) and their caregivers.

Probabilistic Multimodal Representation Learning

no code implementations1 Jan 2021 Leila Pishdad, Ran Zhang, Afsaneh Fazly, Allan Jepson

Learning multimodal representations is a requirement for many tasks such as image--caption retrieval.

How coherent are neural models of coherence?

no code implementations COLING 2020 Leila Pishdad, Federico Fancellu, Ran Zhang, Afsaneh Fazly

Despite the recent advances in coherence modelling, most such models including state-of-the-art neural ones, are evaluated on either contrived proxy tasks such as the standard order discrimination benchmark, or tasks that require special expert annotation.

Accurate polyglot semantic parsing with DAG grammars

no code implementations Findings of the Association for Computational Linguistics 2020 Federico Fancellu, {\'A}kos K{\'a}d{\'a}r, Ran Zhang, Afsaneh Fazly

We significantly improve upon this work, by proposing a simpler architecture as well as more efficient training and inference algorithms that can always guarantee the well-formedness of the generated graphs.

SREC: Proactive Self-Remedy of Energy-Constrained UAV-Based Networks via Deep Reinforcement Learning

1 code implementation17 Sep 2020 Ran Zhang, Miao Wang, Lin X. Cai

Energy-aware control for multiple unmanned aerial vehicles (UAVs) is one of the major research interests in UAV based networking.

Dropout during inference as a model for neurological degeneration in an image captioning network

no code implementations11 Aug 2018 Bai Li, Ran Zhang, Frank Rudzicz

We replicate a variation of the image captioning architecture by Vinyals et al. (2015), then introduce dropout during inference mode to simulate the effects of neurodegenerative diseases like Alzheimer's disease (AD) and Wernicke's aphasia (WA).
