An Study Of Sentiment Analysis Methods For Mandarin Chinese, Thalia Celeste Chai-Zhang
An Study Of Sentiment Analysis Methods For Mandarin Chinese, Thalia Celeste Chai-Zhang
Senior Projects Spring 2020
Sentiment analysis is the study of automated methods of emotion detection in language and speech. It is an area of much active study, and has seen significant progress in improving accuracy over recent years. Many studies however are conducted on datasets of English and other Indo-European languages. We apply well studied methods for sentiment analysis to a Mandarin Chinese data set and compare the accuracies achieved against eachother and other studies. Our findings indicate that methods for improving sentiment analysis accuracy for English may not be as applicable to Mandarin Chinese.

Testing And Improving An Optimization-Based Digital Colorblindness Corrective Filter, Zachary Kenneth Mcintyre
Senior Projects Fall 2020
Computers often communicate essential information via color which is lost to colorblind users. In order to address this information loss, designers and computer scientists have created a variety of different correction methods to improve computer accessibility. One such method was created by Luke Jefferson and Richard Harvey in their 2006 paper, “Accommodating Color Blind Computer Users” which consists of a difference histogram, differences of key colors, optimization and interpolation to adjust images for specific types of congenital colorblindness. I have recreated their algorithm as well as their original test images. I then conducted extensive tests on challenging images to examine …
The Spiral Model For Generative Harmony, Jackson Guy Spargur
The Spiral Model For Generative Harmony, Jackson Guy Spargur
Senior Projects Spring 2020
Generative music is a broad and well-explored field, in which researchers have attempted various approaches at creating algorithmic models for the creation of music. Researchers may attempt to model the composition of melody, or of musical phrase structure, or, as is the focus of this paper, the harmonization of multiple voices. I use as the core of my model Elaine Chew’s “Spiral Array”, outlined in her 2000 thesis “Towards a Mathematical Model Of Tonality”. Chew’s applications for this model were all analytical, gaining insights about human-composed pieces of music by running them through her model. My project is comprised of …
Relating Sentiment Expressed By Financial Twitter Accounts And Financial Index Price Movement, Jacob Edelstein Lester
Relating Sentiment Expressed By Financial Twitter Accounts And Financial Index Price Movement, Jacob Edelstein Lester
Senior Projects Spring 2020
We apply sentiment analysis to correlate price movement for two financial indices with sentiment expressed on Twitter by a select group of 93 influential financial users. We gathered close prices for the VIX and SPX indices for one month from March through April 2020 during the early stage of the COVID-19 pandemic in the U.S. as schools and businesses shut down. Tweets were also gathered during this period, although there is a large gap in collected tweets of about two weeks. We examine correlations based on five temporal resolutions from 60 minutes to 1440, which is equivalently one day.. We …
Carbon Footprint Of Machine Learning Algorithms, Gigi Hsueh
Carbon Footprint Of Machine Learning Algorithms, Gigi Hsueh
Senior Projects Spring 2020
With the rapid development of machine learning, deep learning has demonstrated superior performance over other types of learning. Research made possible by big data and high-end GPU's enabled those research advances at the expense of computation and environmental costs. This will not only slow down the advancement of deep learning research because not all researchers have access to such expensive hardware, but it also accelerates climate change with increasing carbon emissions. It is essential for machine learning research to obtain high levels of accuracy and efficiency without contributing to global warming. This paper discusses some of current approaches in estimating …

Senior Project submitted to The Division of Science, Mathematics and Computing of Bard College.
From Rural To Urban: Understanding America Through The Census, R. Owen Hartman
From Rural To Urban: Understanding America Through The Census, R. Owen Hartman
Senior Projects Spring 2020
The first ever Senior Project to combine Historical Studies and Computer Science. Examining United States Census data from 1870 to 1930, "From Rural to Urban" explores the changes in American life that occurred during the industrial revolution at the turn of the 20th century.
Connectedness In Cayley Graphs And P/Np Dichotomy For Quay Algebras, Thuy Trang Nguyen
Connectedness In Cayley Graphs And P/Np Dichotomy For Quay Algebras, Thuy Trang Nguyen
Senior Projects Spring 2020
This senior thesis attempts to determine the extent to which the P/NP dichotomy of finite algebras (as proven by Bulatov, et.al in 2017) can be cast in terms of connectedness in Cayley graphs. This research is motivated by Prof. Robert McGrail's work ``CSPs and Connectedness: P/NP-Complete Dichotomy for Idempotent, Right Quasigroups" published in 2014 in which he demonstrates the strong correspondence between tractability and total path-connectivity in Cayley graphs for right, idempotent quasigroups. In particular, we will introduce the notion of total V-connectedness and show how it could be potentially used to phrase the dichotomy in terms of connectivity for …
Automated Exercise Generation In Mobile Language Learning, Rayo Verweij
Automated Exercise Generation In Mobile Language Learning, Rayo Verweij
Senior Projects Spring 2020
The Language Lion is an Android application that teaches basic Dutch to English speakers. While mobile language learning has increased exponentially in popularity, course creation is still labor-intensive. By contrast, the Language Lion uses a map of Dutch to English lexemes, a context-free grammar, and a modified version of the SimpleNLG sentence realizer to automatically generate semi-random translation exercises for the student. Each component is evaluated individually to find and analyze the particular roadblocks in automated exercise generation for mobile language learning.
A Machine Learning Approach To The Perception Of Phrase Boundaries In Music, Evan Matthew Petratos
A Machine Learning Approach To The Perception Of Phrase Boundaries In Music, Evan Matthew Petratos
Senior Projects Fall 2020
Segmentation is a well-studied area of research for speech, but the segmentation of music has typically been treated as a separate domain, even though the same acoustic cues that constitute information in speech (e.g., intensity, timbre, and rhythm) are present in music. This study aims to sew the gap in research of speech and music segmentation. Musicians can discern where musical phrases are segmented. In this study, these boundaries are predicted using an algorithmic, machine learning approach to audio processing of acoustic features. The acoustic features of musical sounds have localized patterns within sections of the music that create aurally …
The Use Of Virtual Manipulatives In Teaching Sorting Algorithms, Olivia Witanowska
The Use Of Virtual Manipulatives In Teaching Sorting Algorithms, Olivia Witanowska
Senior Projects Fall 2020
This project builds an online tool for users to practice tracing sorting algorithms on a virtual set of cards. Sorting algorithms are crucial to computer science. Visualization of such algorithms can aid in cementing the concepts. The purpose of a virtual manipulative is to create a similar effect of a physical manipulative but on a digital platform so that it is more accessible than its physical alternative. This project is motivated by the educational adjustments needed to be made during the 2020 Covid-19 pandemic. By building off of a previous Deck of Cards project, an algorithm to check a user’s …
The Impact Of Live Coding Within An Educational And Performance Setting, Alexus Renee Foster
The Impact Of Live Coding Within An Educational And Performance Setting, Alexus Renee Foster
Senior Projects Spring 2020
For the past three semesters at Bard, live coding has become my newest form of creative expression and performance. This method of coding involves either creating on the spot from scratch or editing pre-existing code in a real time manner. There is no real set structure or steps that must be followed, however, one rule must always be followed: show your code. In the classroom, live coding occurs when the professor demonstrates some algorithm by displaying the program on a projector for the entire class to observe. During musical performances, the same improvisational nature of live coding is also present, …
