Kinematics Modeling of Peroxy Free Radicals: A Deep Reinforcement Learning Approach

no code implementations12 Apr 2024 Subhadarsi Nayak, Hrithwik Shalu, Joseph Stember

Tropospheric ozone, known as a concerning air pollutant, has been associated with health issues including asthma, bronchitis, and impaired lung function.

Deep neuroevolution to predict primary brain tumor grade from functional MRI adjacency matrices

no code implementations26 Nov 2022 Joseph Stember, Mehrnaz Jenabi, Luca Pasquini, Kyung Peck, Andrei Holodny, Hrithwik Shalu

Whereas MRI produces anatomic information about the brain, functional MRI (fMRI) tells us about neural activity within the brain, including how various regions communicate with each other.

Direct evaluation of progression or regression of disease burden in brain metastatic disease with Deep Neuroevolution

no code implementations24 Mar 2022 Joseph Stember, Robert Young, Hrithwik Shalu

We applied the CNNs to our training set, as well as a separate testing set with the same class balance of 25 progression and 25 regression images.

Deep reinforcement learning with automated label extraction from clinical reports accurately classifies 3D MRI brain volumes

no code implementations17 Jun 2021 Joseph Stember, Hrithwik Shalu

Part 2: Then, using these labels, whereas the supervised approach quickly overfit the training data and as expected performed poorly on the testing set (66% accuracy, just over random guessing), the reinforcement learning approach achieved an accuracy of 92%.

Deep Neural Network Based Differential Equation Solver for HIV Enzyme Kinetics

no code implementations16 Feb 2021 Joseph Stember, Parvathy Jayan, Hrithwik Shalu

Purpose: We seek to use neural networks (NNs) to solve a well-known system of differential equations describing the balance between T cells and HIV viral burden.

Unsupervised deep clustering and reinforcement learning can accurately segment MRI brain tumors with very small training sets

no code implementations24 Dec 2020 Joseph Stember, Hrithwik Shalu

Materials and Methods: We initially clustered images using unsupervised deep learning clustering to generate candidate lesion masks for each MRI image.

Deep reinforcement learning to detect brain lesions on MRI: a proof-of-concept application of reinforcement learning to medical images

no code implementations6 Aug 2020 Joseph Stember, Hrithwik Shalu

Reinforcement learning predicted testing set lesion locations with 85% accuracy, compared to roughly 7% accuracy for the supervised deep network.

Cross-modality Knowledge Transfer for Prostate Segmentation from CT Scans

no code implementations26 Aug 2019 Yucheng Liu, Naji Khosravan, Yulin Liu, Joseph Stember, Jonathan Shoag, Christopher E. Barbieri, Ulas Bagci, Sachin Jambawalikar

By using SynCT images (without segmentation labels) and MR images (with segmentation labels available), we have trained a deep segmentation network for precise delineation of prostate from real CT scans.
