Quantum Theory and Application of Contextual Optimal Transport

no code implementations22 Feb 2024 Nicola Mariella, Albert Akhriev, Francesco Tacchino, Christa Zoufal, Juan Carlos Gonzalez-Espitia, Benedek Harsanyi, Eugene Koskin, Ivano Tavernelli, Stefan Woerner, Marianna Rapsomaniki, Sergiy Zhuk, Jannis Born

In cases where paired data measurements ($\mu$, $\nu$) are coupled to a context variable $p_i$ , one may aspire to learn a global transportation map that can be parameterized through a potentially unseen con-text.

Super Resolution for Turbulent Flows in 2D: Stabilized Physics Informed Neural Networks

no code implementations15 Apr 2022 Mykhaylo Zayats, Małgorzata J. Zimoń, Kyongmin Yeo, Sergiy Zhuk

In addition, to compensate for decrease of observer's performance due to the presence of unknown destabilizing forcing, the network is designed to estimate the contribution of the unknown forcing implicitly from the data over the course of training.

A Real-Time Region Tracking Algorithm Tailored to Endoscopic Video with Open-Source Implementation

1 code implementation16 Mar 2022 Jonathan P. Epperlein, Sergiy Zhuk

With a video data source, such as multispectral video acquired during administration of fluorescent tracers, extraction of time-resolved data typically requires the compensation of motion.

Reinforcement Learning with Algorithms from Probabilistic Structure Estimation

1 code implementation15 Mar 2021 Jonathan P. Epperlein, Roman Overko, Sergiy Zhuk, Christopher King, Djallel Bouneffouf, Andrew Cullen, Robert Shorten

In some cases, the environment is not influenced by the actions of the RL agent, in which case the problem can be modeled as a contextual multi-armed bandit and lightweight myopic algorithms can be employed.

Perfusion Quantification from Endoscopic Videos: Learning to Read Tumor Signatures

no code implementations25 Jun 2020 Sergiy Zhuk, Jonathan P. Epperlein, Rahul Nair, Seshu Thirupati, Pol Mac Aonghusa, Ronan Cahill, Donal O'Shea

Intra-operative identification of malignant versus benign or healthy tissue is a major challenge in fluorescence guided cancer surgery.

Spatial Positioning Token (SPToken) for Smart Mobility

no code implementations16 May 2019 Roman Overko, Rodrigo H. Ordonez-Hurtado, Sergiy Zhuk, Pietro Ferraro, Andrew Cullen, Robert Shorten

We introduce a permissioned distributed ledger technology (DLT) design for crowdsourced smart mobility applications.

Bayesian Classifier for Route Prediction with Markov Chains

no code implementations31 Aug 2018 Jonathan P. Epperlein, Julien Monteil, Ming-ming Liu, Yingqi Gu, Sergiy Zhuk, Robert Shorten

We present here a general framework and a specific algorithm for predicting the destination, route, or more generally a pattern, of an ongoing journey, building on the recent work of [Y. Lassoued, J. Monteil, Y. Gu, G. Russo, R. Shorten, and M. Mevissen, "Hidden Markov model for route and destination prediction," in IEEE International Conference on Intelligent Transportation Systems, 2017].

Where computer vision can aid physics: dynamic cloud motion forecasting from satellite images

no code implementations30 Sep 2017 Sergiy Zhuk, Tigran Tchrakian, Albert Akhriev, Siyuan Lu, Hendrik Hamann

The prediction phase consists of utilizing a linear transport equation, which describes the propagation of COD images in the fluid flow predicted by NSE, to estimate the future motion of the COD images.
