Dr. Manaris Invited to Present at University of Utah’s Arts & Technology Lecture Series

On April 21, 2015, Dr. Bill Manaris was invited to the University of Utah, where he presented “Computing in the Arts: A New Major for Creative People” as part of the Arts & Technology Lecture Series.

CITA Program Director

Computing in the Arts (CITA) is an innovative interdisciplinary major, which combines computer science with artistic theory and practice. CITA is relatively easy to implement because it repurposes existing courses and resources. At the College of Charleston, this involves three tracks (music, studio art, and theatre). CITA incorporates four synthesis courses, one per academic year, to help students interweave the two distinct curricular experiences. In the four years of its existence, CITA has increased participation in computing by 23% mainly from an underserved population (students interested in the arts). Approximately 49% of these students are women. These students tend to be strong in design and creativity, thus enriching the field with professionals who can envision new technologies and surprising innovations.

The talk provided inspiration behind CITA, discussed implementation highlights at the College of Charleston, and presented several projects that have emerged as a result of CITA. These include a Laptop Orchestra, Monterey Mirror (a computer musician that listens to humans and responds with new material in real-time), Jython Music (a Python environment for music making and creative programming activities, intended for musicians and programmers), Harmonic Navigator (a system for exploring harmonic spaces in J.S. Bach Chorales and other music in real-time), Time Jitters (a four-projector interactive gallery installation synthesizing artificial intelligence and human-computer interaction with music and visual art), and Loutraki Sunset (a music composition created by converting a beautiful image to aesthetically pleasing music).

“Galaxy Classification Using Deep Belief Networks”

The massive number of galaxies in the universe poses a central problem for astronomers and requires novel techniques to be used for classification.  To cope with the vast amounts of data created by modern observations, past research organizations, specifically Galaxy Zoo (part of the citizen science project Zooniverse), have crowd-sourced morphological classification techniques inviting members of the public to log onto a website and classify the data. The technique has been effective, but we hypothesize that we should be able to apply machine learning techniques to classify the data as well as humans. We analyze the performance on this classification task for a deep learning neural network constructed by stacking restricted Boltzmann machines on top of one another, also referred to as a deep belief network.

“Extending scalable deep neural networks to multi-way classification”

Deep learning models that capture high-level abstractions in data often outperform standard models for classification problems. On large datasets, significant gains in classification accuracy can be achieved by using computationally efficient non-linear transforms, such as using deep neural networks (DNNs) or stacked denoising autoencoders (SDAEs), to model higher-level abstractions in the data before using standard models for classification on the transformed dataset.  Le et al. have developed Fastfood, a method for approximating kernel expansions in loglinear time; kernel expansions are performed in neural networks and must be calculated for every pair of training samples–this quickly becomes costly for large datasets, and is partially resolved by using Fastfood kernel expansions. As the existing paper describes using Fastfood optimized neural networks (FONNs) for binary classification problems, we extend the algorithm such that it can be applied to classification problems with more than two classes using a logistic classifier.

“ccOPLS: Confounder Correcting Orthogonal Projections to Latent Structures”

David Moore

David Moore

Predicting biological phenotypes from next-generation high-throughput data sources is essential to bioinformatics. However, confounding variables such as gender, age, and habitat can skew the results of such data, leading to biased and inaccurate results. While work has already been done to create a confounder correcting method in Support Vector Machines by Li et. al, there is no such method available for a classification algorithm suited for high-dimensional data with a small sample size (d >> n). We have extended Li et. al’s confounder correcting algorithm for Support Vector Machines (ccSVM) to allow Orthogonal Projections to Latent Structures (O-PLS) to account for confounding variables. We demonstrate that our novel method improves the accuracy of a non-confounding corrected OPLS implementation and that it is better suited to datasets that exhibit the d >> n pattern.
