Classification of twitter trends using feature ranking and forward feature selection
(University of Missouri--Columbia, 2015)
, we attempt to solve this challenge using various machine learning techniques. This thesis includes a new approach for classifying Twitter trends by adding a layer of feature selection and feature ranking. A variety of feature ranking algorithms...
Integration Features in the Development of Software Product Line Architecture
(2015-08-12)
, the difficulty of relating product line features to PLA, and the overhead of manually creating and maintaining variation points in PLA. The approach is implemented and integrated in ArchStudio, an Eclipse-based architecture development toolset. The developed tool...
A flexible speech feature converter based on an enhanced architecture of U-net
(University of Missouri--Columbia, 2020)
In order to analyze speech or audio, many methods are applied to transform the time domain signals into various features such as the mel spectral features and WORLD vocoder features. These two types of features can both be extracted from speech...
Cooking up a sports feature story: dissecting the writer-editor decisions and operations that lead to sports features making it to publication
(University of Missouri--Columbia, 2015)
As story structures and distribution models in journalism change, storytelling remains a valuable asset to writers and editors, especially in sports departments. But before you can tell a story, you need a topic. I aimed ...
Acoustic feature-based sentiment analysis of call center data
(University of Missouri--Columbia, 2017)
. A typical approach is to find a set of acoustic features from audio data that can indicate or predict a customer's attitude, opinion, or emotion state. For audio signals, acoustic features have been widely used in many machine learning applications...
Processing of Presolar Grains around Post-Asymptotic Giant Branch Stars: Silicon Carbide as the Carrier of the 21 Micron Feature
(Institute of Physics, 2004)
Some proto-planetary nebulae (PPNs) exhibit an enigmatic feature in their infrared spectra at ~21 μm. This feature is not seen in the spectra of either the precursors to PPNs, the asymptotic giant branch (AGB) stars, or the successors of PPNs...
The 21 micron and 30 micron circumstellar dust features in evolved C-rich objects
(2008)
The 21micron and 30micron bands are the strongest dust emission features detected in evolved low- and intermediate-mass C-rich stars (i.e. asymptotic giant branch [AGB] stars, proto-planetary nebulae [PPN], and planetary nebulae [PN]). While the 21...
M.D. day features speakers, singers, and students, old and new
(University of Missouri. Alumni Association, 1973)
"The 1972 M.D. Day program, coinciding with the School's 100th birthday, featured six prominent alumni."--Page 15...
Face verification using high dimensional feature

Astromineralogy of the 13 μm Feature in the Spectra of Oxygen-rich Asymptotic Giant Branch Stars. I. Corundum and Spinel
(American Astronomical Society, 2006)
Asymptotic giant branch (AGB) stars have several interesting infrared spectral features. Approximately half the oxygen-rich AGB stars to be investigated spectroscopically exhibit a feature at ~13 μm. The carrier of this feature has not yet been...
Estimation of crop residue cover in high-resolution RGB images using features from a pre-trained convolutional neural network
(University of Missouri--Columbia, 2022)
,400 ROI images; 3,000 used for cross validation and training (data collected in 2018) and 1,400 used for testing (data collected in 2019). The percent residue for each ROI image (ground truth) was determined by a bullseye grid method (n = 100). Features...
Singsations rhapsody in jazz featuring vocal jazz emsemble and rhythm combo

A flyer advertising Singsations Rhapsody in Jazz.
iHear – Lightweight Machine Learning Engine with Context Aware Audio Recognition Model
(University of Missouri–Kansas City, 2016)
With the increasing popularity and affordability of smartphones, there is a high demand to add
machine-learning engines to smartphones. However, Machine Learning with smartphones is typically
not feasible due to the heavy ...

Supervised learning methods for hand-held ground penetrating radar
(University of Missouri--Columbia, 2016)
, computational methods for detecting dangerous targets in GPR data are explored. First, an anomaly detection algorithm which can act as a prescreener is described. Then, two feature extraction methods are implemented in order to extract relevant features from...
Subsurface explosive hazard detection using MIMO forward-looking ground penetrating radar
(University of Missouri--Columbia, 2015)
locations. Alarm locations have log-Gabor statistical features and spectral features, among others, extracted from multiple polarizations. The ability of these features to reduce the number of false alarms and increase the probability of detection...
Confocal microscopy imaging analysis of plant morphodynamics
(University of Missouri--Columbia, 2010)
. Key features may then be identified and an abstracted version of the image may be generated. Next, motion analysis may be performed on the structures within the pollen tube. Six methods of point feature detection algorithms are discussed...
