Robust Learning Protocol for Federated Tumor Segmentation Challenge

no code implementations16 Dec 2022 Ambrish Rawat, Giulio Zizzo, Swanand Kadhe, Jonathan P. Epperlein, Stefano Braghin

In this work, we devise robust and efficient learning protocols for orchestrating a Federated Learning (FL) process for the Federated Tumor Segmentation Challenge (FeTS 2022).

Extracting, Visualizing, and Learning from Dynamic Data: Perfusion in Surgical Video for Tissue Characterization

no code implementations9 Nov 2022 Jonathan P. Epperlein, Niall P. Hardy, Pol Mac Aonghusa, Ronan A. Cahill

Intraoperative assessment of tissue can be guided through fluorescence imaging which involves systemic dosing with a fluorophore and subsequent examination of the tissue region of interest with a near-infrared camera.

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.

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].
