Optimizing Decision-Making In A Cerebral Palsy Model Using Reinforcement Learning, Richard Ampah
Optimizing Decision-Making In A Cerebral Palsy Model Using Reinforcement Learning, Richard Ampah
Pitzer Senior Theses
This study presents an original interdisciplinary investigation into how reinforcement learning (RL) can model motor and cognitive defects and potentially improve motor and cognitive functions in individuals with cerebral palsy (CP), a non-progressive neurological disorder that impairs movement and adaptability. Integrating computational neuroscience and machine learning, the research applies policy gradient methods and Markov Decision Processes (MDPs) to simulate adaptive learning in agents with and without CP-related constraints.
The central aim is to compare the cumulative rewards of optimal policies, derived from value iteration, and human-like learning policies using the REINFORCE algorithm, both with and without the Bellman baseline. The …
Effects Of The Injury Recovery Process On Neuromuscular Activation In An Uninjured Ankle, Mark Tankersley
Effects Of The Injury Recovery Process On Neuromuscular Activation In An Uninjured Ankle, Mark Tankersley
CMC Senior Theses
This study was conducted to observe the effects of changed activity levels due to a major lower extremity injury on ankle function in the uninjured leg. Neuromuscular activation in the Gastric Medialis (GAS) and Tibialis Anterior (TA), the muscles primarily responsible for movement at the ankle, was assessed in 8 athletes at the Claremont Colleges while walking on a flat surface, stepping up a 15º incline, and stepping up a 27º incline. Athletes were split into two groups based on injury condition: a “recovered” group (n=4) who had suffered a major lower extremity injury in the last two years in …
Ccl11 As A Biomarker For The In Vivo Diagnosis Of Chronic Traumatic Encephalopathy, Robert Weissenfels
Ccl11 As A Biomarker For The In Vivo Diagnosis Of Chronic Traumatic Encephalopathy, Robert Weissenfels
CMC Senior Theses
Chronic traumatic encephalopathy is the neurodegenerative disease that is ascribed to the long term development of cognitive, behavioral, emotional, and motor deficits as a result of the exposure to high amounts of sub concussive traumatic brain injuries. The disease has gained recent popularity in the media for its prevalence in American football as a response to recent research that has suggested the prominence of the disease in nearly every NFL player that is examined post mortem. This has produced a growing concern for the consequences of head impact and participation in contact sports. Despite media attention, little is currently known …
