Robust Model Based Reinforcement Learning Using $\mathcal{L}_1$ Adaptive Control

Autor: Sung, Minjun, Karumanchi, Sambhu H., Gahlawat, Aditya, Hovakimyan, Naira

We introduce $\mathcal{L}_1$-MBRL, a control-theoretic augmentation scheme for Model-Based Reinforcement Learning (MBRL) algorithms. Unlike model-free approaches, MBRL algorithms learn a model of the transition function using data and use it to desig

Microglia ameliorate delirium-like phenotypes in a murine model of acute ventilator-induced lung injury

Autor: Landon Scott, Kevin D. Winzey, Debbie Moreira, Catherine Bresee, Jean‑Philippe Vit, Warren G. Tourtellotte, S. Ananth Karumanchi, Shouri Lahiri

Publikováno v: Journal of Neuroinflammation, Vol 21, Iss 1, Pp 1-12 (2024)

Abstract Background Delirium affects 50–85% of patients on mechanical ventilation and is associated with increased mortality, prolonged hospitalization, and a three-fold higher risk of dementia. Microglia, the resident immune cells of the brain, ex

Motion Primitives Based Kinodynamic RRT for Autonomous Vehicle Navigation in Complex Environments

Autor: Kedia, Shubham, Karumanchi, Sambhu Harimanas

Publikováno v: IROS Workshop 2022

In this work, we have implemented a SLAM-assisted navigation module for a real autonomous vehicle with unknown dynamics. The navigation objective is to reach a desired goal configuration along a collision-free trajectory while adhering to the dynamic

Data-driven prediction of continuous renal replacement therapy survival

Autor: Davina Zamanzadeh, Jeffrey Feng, Panayiotis Petousis, Arvind Vepa, Majid Sarrafzadeh, S. Ananth Karumanchi, Alex A. T. Bui, Ira Kurtz

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-12 (2024)

Abstract Continuous renal replacement therapy (CRRT) is a form of dialysis prescribed to severely ill patients who cannot tolerate regular hemodialysis. However, as the patients are typically very ill to begin with, there is always uncertainty whethe

A rare case of pediatric distal middle cerebral artery aneurysm

Autor: Rachel Moor, Chance Fleeting, Grace Hey, Chandana Karumanchi, Jason Blatt, Matthew Koch, Jesse Lee Kresak

Publikováno v: SAGE Open Medical Case Reports, Vol 12 (2024)

Pediatric middle cerebral artery aneurysms are often complicated by subsequent rupture and subarachnoid hemorrhage. Unruptured middle cerebral artery aneurysms are rare in infancy. Here, we present a rare case of a 13-month-old male who underwent cli
