The types and rates of label noise in real-world data sets present a challenge to machine learning projects. In this thesis, we propose a novel approach to address this issue. Our method combines a noise modelling technique for correcting label noise across the entire data set with a robust loss...
This paper discusses the merits of providing users variational views when editing variational code. I provide a plugin for the popular Atom Integrated Development Environment (IDE) which replaces #ifdef annotations commonly used by the C PreProcessor (CPP) with colored backgrounds, thus reducing code clutter and attempting to help programmers quickly...
Expensive pricing for laboratory bioreactors proves to be the main barrier-to-entry for lab-scale academic research. Most laboratory bioreactors are priced at $100K+ and require significant training to use, thereby limiting their accessibility. The IDEAL (Intuitive, Developmental And Research Oriented, Easy To Use, Affordable, And Low Volume) Bioreactor aims to solve...
As the link between human microbiomes and health has become more established, the interest in applying statistical approaches to microbiome data to understand the mechanisms behind these links has grown. However, microbiome data is often of unmanageable size, and consequently, producing quality lower dimensional representations of samples is a significant...
Automatic Music Transcription is a growing area of interest in Music Information Retrieval, and recent research has shown promise using onset detection on spectrograms. We propose a deep learning model that takes raw audio as input in order to transcribe a solo piano performance from audio to MIDI without complicated...
The Pacific Islander diaspora in the Pacific Northwest United States is a unique community characterized by diverse cultures, experiences, and motivations for migration. This study aimed to explore the narratives of individuals from different Pacific Islander backgrounds residing in Oregon, shedding light on their reasons for migration and the impact...
This algorithm presents the first steps towards a solution for novice database administrators that helps them transform a non-normalized relational database into a database in the third normal form. The algorithm uses relational algebra operations that apply principles from the third normal form. This provides the database administrator with an...
We present a proof that the number of breakpoints in the arrival function between two terminals in graphs of treewidth ω is n^(O(log²ω) when the edge arrival functions are piecewise linear. This is an improvement on the bound of n^(Θ(log n))by Foschini, Hershberger, and Suri for graphs without any bound...
This thesis – “The Sweet Roll: A Project in Podcasting Gaming News, Discussions and
Reviews” – assesses the current gaming scene, including games, gamers, news, and
reviews of gaming, and creates a pilot podcast The Sweet Roll as a demonstration and
discussion of what could be done better. Through a...
Augmentative and Alternative Communication (AAC) devices enable people who cannot speak to communicate with others. Unfortunately, they are tedious to use and are believed to lower the satisfaction of interacting with others. This thesis attempted to document the impact that AAC devices have on social interactions, in the hope of...
The widespread adoption of computerized systems around the turn of the century as a means of more efficiently conducting elections introduced more issues than these computer systems were intended to address. Though many of these flaws were not considered for years or decades after the introduction of digital election infrastructure,...
The agricultural industry in the Western United States continues to possess issues of overwatering, accounting for over 80% of consumed water per year in the country. While technologies such as satellite imaging and sensor networks have slowly improved irrigation Best Management Practices to reduce superfluous water consumption, limitations associated with...
This research paper describes the impacts of a new programming class on first-year, non-CS engineering students. In the spring of 2021, the College of Engineering at Oregon State University piloted a new programming course that will be required of all engineering majors in the following academic years. We used the...
This project studied how a user's handedness affects his or her ability to use a
special-purpose handheld digital device such as a digital camera or rangefinder. More
specifically, it sought to identify how handedness affects speed and accuracy when
navigating within a menu system. 24 participants were given 8 menu...
Modern technology has enabled the advancement of biological research through the use of powerful machines and computers as well as innovative computer programs. Advances in sequencing technology and software enable us to make de novo assemblies of organism genomes, and the development of specialized computer programs can automate routine but...
This thesis presents innovative pedagogical approaches to teach fundamental Computer Science (CS) concepts, such as abstraction, representation, algorithms, and computation utilizing manipulatives, which are physical objects that students interact with to teach or reinforce a concept. Teaching and learning with manipulatives has a long history in science and mathematics education,...
The use of genetic algorithms to compose music and generate sounds is an area of interest in the artificial intelligence field. Music and instrument sounds have known rules and structures that can be followed which make them well-suited for genetic algorithms. However, genetic algorithms still struggle to generate sounds comparable...
In a big data day and age, there is an abundance of information and we now have the tools to understand it with data mining and machine learning algorithms. With the rise and fall and rise again of Bitcoin, the finance industry and society itself is caught in between. There...
We analyze merger parameters of binary black hole systems (BBHSs), including orbital separation and time at which gravitational and viscous timescales intersect for all combinations of black holes (BHs) in the range 1-100 solar masses. Our initial examination of BBHS merger parameters using the assumption R=0.5r reveals suspicious trends in...
We take for granted how quickly we, as humans, form mental models of the world around us. By the time we are toddlers, we have an observable intuition around the physical rules of the world. Stacking blocks such that they don’t fall over becomes such a trivial task, that it...
