How Can I Help You? Social Support In The Context Of Attachment Insecurity., Julian Domingo Fuentes Dec 2020

How Can I Help You? Social Support In The Context Of Attachment Insecurity., Julian Domingo Fuentes

Theses - ALL

People in close relationships support each other through various means yet support attempts may be unsuccessful. I propose that people prefer support behaviors matched to their dispositional needs (the personal context) and their relationship with the support provider (the interpersonal context). I also propose that this kind of support is most effective at enhancing relationship quality and reducing personal distress. Attachment theory provides a framework for characterizing differences in dispositional needs and in the specific relationship context between a support recipient and support provider. In three studies, I tested whether one’s trait and relationship-specific attachment orientations are associated with preferences …

End-To-End Learning Utilizing Temporal Information For Vision- Based Autonomous Driving, Dapeng Guo Dec 2020

End-To-End Learning Utilizing Temporal Information For Vision- Based Autonomous Driving, Dapeng Guo

Master's Projects

End-to-End learning models trained with conditional imitation learning (CIL) have demonstrated their capabilities in driving autonomously in dynamic environments. The performance of such models however is limited as most of them fail to utilize the temporal information, which resides in a sequence of observations. In this work, we explore the use of temporal information with a recurrent network to improve driving performance. We propose a model that combines a pre-trained, deeper convolutional neural network to better capture image features with a long short-term memory network to better explore temporal information. Experimental results indicate that the proposed model achieves performance gain …


Multi-Agent Deep Reinforcement Learning For Walkers, Inhee Park Dec 2020

Multi-Agent Deep Reinforcement Learning For Walkers, Inhee Park

Master's Projects

This project was motivated by seeking an AI method towards Artificial General Intelligence (AGI), that is, more similar to learning behavior of human-beings. As of today, Deep Reinforcement Learning (DRL) is the most closer to the AGI compared to other machine learning methods. To better understand the DRL, we compares and contrasts to other related methods: Deep Learning, Dynamic Programming and Game Theory.

We apply one of state-of-art DRL algorithms, called Proximal Policy Op- timization (PPO) to the robot walkers locomotion, as a simple yet challenging environment, inherently continuous and high-dimensional state/action space.

Snowpack Reconstruction In North America Using Tree-Rings, Bethany Lynn Coulthard, Kevin J. Anchukaitis, Gregory T. Pederson, Edward Cook, Jeremy Littell, Dan J. Smith

Geoscience Faculty Research

Climate change has contributed to recent declines in mountain snowpack and earlier runoff, which in turn has intensified hydrological droughts in western North America. Climate model projections suggest that continued and severe snowpack reductions are expected over the 21st century, with profound consequences for ecosystems and human welfare. Yet the current understanding of trends and variability in mountain snowpack is limited by the relatively short and strongly temperature forced observational record. Motivated by the urgent need to better understand snowpack dynamics in a long-term, spatially coherent framework, here we examine snow-growth relationships in western North American tree-ring chronologies. We present …

We present the occurrence rates for rocky planets in the habitable zones (HZs) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar properties. We provide the first analysis in terms of star-dependent instellation flux, which allows us to track HZ planets. We define η⊕ as the HZ occurrence of planets with radii between 0.5 and 1.5 R⊕ orbiting stars with effective temperatures between 4800 and 6300 K. We find that η⊕ for the conservative HZ is between... (See article for full abstract).


Towards A Reduced Phase Space Quantization In Loop Quantum Cosmology With An Inflationary Potential, Kristina Giesel, Bao Fei Li, Parampreet Singh Dec 2020

Towards A Reduced Phase Space Quantization In Loop Quantum Cosmology With An Inflationary Potential, Kristina Giesel, Bao Fei Li, Parampreet Singh

Faculty Publications

We explore a reduced phase space quantization of loop quantum cosmology (LQC) for a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe filled with reference fields and an inflaton field in a Starobinsky inflationary potential. We consider three separate cases in which the reference fields are taken to be the Gaussian dust, the Brown-Kuchař dust, and massless Klein-Gordon scalar reference fields respectively. This is a "two-fluid"model in which reference fields act as global clocks providing a physical time in an inflationary spacetime, and allow bypassing various technical hurdles in conventional quantum cosmological models. The reduced phase space is obtained in terms of the …
