Item Improving the Learning Platform for the Leukocoria Detection Project(2016-08-31) Boer, James; Hamerly, Gregory James, 1977-ABSTRACT Improving the Learning Platform for the Leukocoria Detection Project James Boer, M.S. Mentor: Gregory J. Hamerly, Ph.D. In this paper we describe a new and signi cantly improved learning platform for the leukocoria detection project. We have developed an easily maintainable and extensible system that can train hundreds of semi-random convolutional neural networks very quickly on GPUs. Docker is used to enable simple and platform-agnostic deployment of the system. The Torch machine learning library is used to train the convolutional neural networks and a PostgreSQL database is used to store the training results. A literature review of recent convolutional neural network research is done to nd methods of improving accuracy. Training results are promising, with single-network performance at 96.6% using minimal data and 99.5% using data augmentationItem Facetag, The Image Managing Service for the Leukocoria Detection Project(2016-05-27) Cibur, Vaclav; Hamerly, Gregory James, 1977-Item Recommendations Made Easy(2014-06-23) Guinness, Darren, 1990-; Karbasi, Seyedeh Paniz, 1986-; Nazarov, Rovshen; Speegle, Gregory David.Fueled by ever-growing data, the need to provide recommendations for consumers, and the considerable domain knowledge required to implement distributed large scale graph solutions we sought to provide recommendations for users with minimal required knowledge. For this reason in this paper we implement a generalizable 'API-like' access to collaborative filtering. Three algorithms are introduced with three execution plans in order to accomplish the collaborative filtering functionality. Execution is based on memory constraints for scalability and our initial tests show promising results. We believe this method of large-scale generalized 'API-like' graph computation provides not only good trade-off between performance and required knowledge, but also the future of distributed graph computation.Item Matrix Representations of GF(p[superscript n]) over GF(p)(2014-01-31) Maurer, Peter M.We show that any non-singular nxn matrix of order p[superscript n]-1 over GF(p) is a generator of a matrix representation of GF(p[superscript n]). We also determine the number of matrix representations of GF(p[superscript n])GF(p) over GF(p), and then number of order p[superscript n]-1 matrices in the general linear group of degree n over GF(p). The theorems are easily generalizable to arbitrary field extensions.Item Fields and Cyclic Codes for Error Detection(2014-01-14) Hess, Rachel Nicole.This technical report discusses some of the aspects of error detection using finite fields.Item The Conjugacy Classes of 3x3 and 4x4 Matrices Over GF(2)(2013-09-20) Maurer, Peter M.The general linear groups over GF(2) have an intricate and interesting structure.
