An Adaptive Memory-Based Reinforcement Learning Controller, Keith August Cissell Dec 2018

An Adaptive Memory-Based Reinforcement Learning Controller, Keith August Cissell

MSU Graduate Theses

Recently, the use of autonomous robots for exploration has drastically expanded--largely due to innovations in both hardware technology and the development of new artificial intelligence methods. The wide variety of robotic agents and operating environments has led to the creation of many unique control strategies that cater to each specific agent and their goal within an environment. Most control strategies are single purpose, meaning they are built from the ground up for each given operation. Here we present a single, reinforcement learning control solution for autonomous exploration intended to work across multiple agent types, goals, and environments. The solution presented ...


Modeling Memory: Exploring The Relationship Between Word Overlap And Single Word Norms When Predicting Judgments And Recall, Nicholas Pruett Maxwell May 2018

Modeling Memory: Exploring The Relationship Between Word Overlap And Single Word Norms When Predicting Judgments And Recall, Nicholas Pruett Maxwell

MSU Graduate Theses

This study examined the interactive relationship between associative, semantic, and thematic word pair strength when predicating item relatedness judgments and cued-recall performance. In Experiment One, 112 participants were shown word pairs with varied levels of associative, semantic, and thematic overlap (measured with forward strength, cosine, and latent semantic analysis) and were asked to judge how related item pairs were before taking a cued-recall test. Experiment One had four goals. First, the judgment of associative memory task (JAM) was expanded to include three types of judgments. Next, the and interaction between database norms (FSG, COS, and LSA) was for when predicting ...


Cognitive Origin Of Reported Goals, Nikolas M. Pate Aug 2017

Cognitive Origin Of Reported Goals, Nikolas M. Pate

MSU Graduate Theses

Goal setting theory assumes that goals that drive self-regulation exist in ‘goal structures’ and that asking participants to report their goals draws from these pre-existing structures. This study tested this assumption of pre-existing goals against the notion that goals are generated by goal-setters at the time they are requested to report their goals. A model of working memory was used to differentiate between goals existing in memory or goals generated on the spot. Participants were 211 students from a large Midwestern public university, randomly assigned to one of two groups. The experimental group participants reported their career goals while also ...


Swamp Boat, Gravy Boat: Memory And Place In Fiction, Kaycie Surrell Dec 2016

Swamp Boat, Gravy Boat: Memory And Place In Fiction, Kaycie Surrell

MSU Graduate Theses

The importance of memory to place is of particular interest to me and forms the basis for the bulk of my work. In my critical introduction I explore the work of authors and essayists who inspire my fiction work through their focus on place and memory. Specific authors include Sandra Cisneros, David Sedaris, and Pam Houston. Through my short fiction pieces I weave together the stories of my childhood from Florida to Missouri into a quilt that covers the important pieces of my life thus far. I am interested in how people are motivated by fear to write around their ...


Climbing The Taxonomy Ladder With Help From The Keyword Method, My Quoc Vu May 2015

Climbing The Taxonomy Ladder With Help From The Keyword Method, My Quoc Vu

MSU Graduate Theses

The keyword method is a mnemonic device used to improve memory. The purpose of this study is to examine whether the keyword method can facilitate higher-order learning and whether the interactive image component of the keyword method is necessary. Participants were asked to study 18 psychologists and their concepts. Undergraduates were randomly assigned to one of four conditions: an own best method control group, and three variations of the keyword method. The variations in the keyword method were related to the "interactive image” aspect of that strategy. The dependent measures measured whether the keyword method can facilitate higher order-learning levels ...
