Designing Smart Applications Using Ar (Augmented Reality), Kimberly A. De La Santa 2018 CUNY New York City College of Technology

Designing Smart Applications Using Ar (Augmented Reality), Kimberly A. De La Santa

Publications and Research

Augmented Reality is rapidly developing in popularity because it brings elements of the virtual world, into our real world. Augmented Reality (AR) is a variation of Virtual Reality (VR). VR technologies immerses a user inside an imaginary environment. While immersed, the user cannot see the real world around them. In contrast, AR allows the user to see the real world, with virtual objects and information intertwined. Therefore, AR supplements reality and enhances the things we see, hear, and feel. This research project will implement a Web page that gives the user the opportunity to experiment with AR.


Improving Asynchronous Advantage Actor Critic With A More Intelligent Exploration Strategy, James B. Holliday 2018 University of Arkansas, Fayetteville

Improving Asynchronous Advantage Actor Critic With A More Intelligent Exploration Strategy, James B. Holliday

Theses and Dissertations

We propose a simple and efficient modification to the Asynchronous Advantage Actor Critic (A3C)

algorithm that improves training. In 2016 Google’s DeepMind set a new standard for state-of-theart

reinforcement learning performance with the introduction of the A3C algorithm. The goal of

this research is to show that A3C can be improved by the use of a new novel exploration strategy we

call “Follow then Forage Exploration” (FFE). FFE forces the agents to follow the best known path

at the beginning of a training episode and then later in the episode the agent is forced to “forage”

and explores randomly ...

Improving The Efficacy Of Context-Aware Applications, Jon C. Hammer 2018 University of Arkansas, Fayetteville

Improving The Efficacy Of Context-Aware Applications, Jon C. Hammer

Theses and Dissertations

In this dissertation, we explore methods for enhancing the context-awareness capabilities of modern computers, including mobile devices, tablets, wearables, and traditional computers. Advancements include proposed methods for fusing information from multiple

logical sensors, localizing nearby objects using depth sensors, and building models to better understand the content of 2D images.

First, we propose a system called Unagi, designed to incorporate multiple logical sensors into a single framework that allows context-aware application developers to easily test new ideas and create novel experiences. Unagi is responsible for collecting data, extracting

features, and building personalized models for each individual user. We demonstrate the ...


Dynamic 3d Network Data Visualization, Brok Stafford 2018 University of Arkansas, Fayetteville

Dynamic 3d Network Data Visualization, Brok Stafford

Computer Science and Computer Engineering Undergraduate Honors Theses

Monitoring network traffic has always been an arduous and tedious task because of the complexity and sheer volume of network data that is being consistently generated. In addition, network growth and new technologies are rapidly increasing these levels of complexity and volume. An effective technique in understanding and managing a large dataset, such as network traffic, is data visualization. There are several tools that attempt to turn network traffic into visual stimuli. Many of these do so in 2D space and those that are 3D lack the ability to display network patterns effectively. Existing 3D network visualization tools lack user ...


Procedural Generation And Rendering Of Ink Bamboo Painting, Yangyang He 2018 College of William and Mary

Procedural Generation And Rendering Of Ink Bamboo Painting, Yangyang He

Undergraduate Honors Theses

This thesis describes an algorithm that generates various ink bamboo paintings. First, a completely procedural model is used to generate the geometric shape of bamboos. The model uses a grammar-like approach that recursively generates new parts of the bamboo in a randomized manner. The random parameters are bounded by rules that simulate the natural form of bamboo.

The structure of the bamboo is represented line segments with directions. Various ink stroke sprites of stalk, branch, or leaf shapes are mapped to line segments, using reverse mapping and bilinear sampling to eliminate aliasing effects. The sprites are mapped in different degrees ...


The Open World Microorganism, Stephen Thompson 2018 Liberty University

The Open World Microorganism, Stephen Thompson

Stephen Thompson

Video games have been creating sprawling open world experiences for years, but as of yet none have ventured to create an authentic inner cell experience, using our knowledge of cells to recreate digitally what it would be like to shrink smaller than one and step inside. The benefits this application could yield are manifold, so this paper references the necessary ingredients and draws up the blueprints for the first three-dimensional, fully explorable, customizable, and interactive microorganism: an invention which could usher in a new age of biological literacy using technology already employed by many video games. The first part of ...

Math Behind Computer Graphics: Piecewise Smooth Interpolation, Jesica Bauer 2018 Carroll College

Math Behind Computer Graphics: Piecewise Smooth Interpolation, Jesica Bauer

Carroll College Student Undergraduate Research Festival

Modern computers are able to create complex imagery with only a small set of information. For example, the fonts on your computer are saved as a set of points and the computer is told how to connect them. Many 3D animations start the same way, where the animation starts as a grid before the rest of the shape is systematically filled in. But how does the computer know how to connect the dots into a mesh? Or know how to create the smooth surface so that it doesn’t look blocky? To solve these problems, we implement mathematical algorithms to ...


An Investigation Of Scenic Visualization Using Virtual Reality During Rehearsal, Cyrus Jian Bonyadi 2018 cbonyadi@rollins.edu

An Investigation Of Scenic Visualization Using Virtual Reality During Rehearsal, Cyrus Jian Bonyadi

Computer Science

In this paper, we discuss the use of virtual reality as a tool for actors during the rehearsal process and assess methods to implement and continue this research in future works. During the rehearsal process, the scenic design is normally introduced to actors close to the end of rehearsals. In introducing a virtual reality environment to train actors, we hoped to help them develop a better understanding of the design at an earlier point in the process. Our investigative pilot study involves two productions in a university theatre, where we render the scenic design of the production for which our ...


Survey Of Techniques For Producing Blended Images: A Case Study Using Rollins College Archives, Hannah Holman 2018 Rollins College

Survey Of Techniques For Producing Blended Images: A Case Study Using Rollins College Archives, Hannah Holman

Computer Science

The Rollins College Archives are a treasure trove of historic resources relating to the college’s history, and they are often underutilized or overlooked by both the student body and the surrounding community. In particular, historic resources are all too often excluded from work in computer science and related fields. This project aims to bridge that gap by bringing the two areas together. To that end, the goal of this project is to merge past and present by blending historic photos with input of a present day scene in order to reveal changes and juxtapositions of the same scene across ...


Speech Emotion Recognition Using Convolutional Neural Networks, Somayeh Shahsavarani 2018 University of Nebraska-Lincoln

Speech Emotion Recognition Using Convolutional Neural Networks, Somayeh Shahsavarani

Computer Science and Engineering: Theses, Dissertations, and Student Research

Automatic speech recognition is an active field of study in artificial intelligence and machine learning whose aim is to generate machines that communicate with people via speech. Speech is an information-rich signal that contains paralinguistic information as well as linguistic information. Emotion is one key instance of paralinguistic information that is, in part, conveyed by speech. Developing machines that understand paralinguistic information, such as emotion, facilitates the human-machine communication as it makes the communication more clear and natural. In the current study, the efficacy of convolutional neural networks in recognition of speech emotions has been investigated. Wide-band spectrograms of the ...

Neighborhood Beautification Graph Layout Through Message Passing, Severino F. Galan, Ole J. Mengshoel 2018 Carnegie Mellon University

Neighborhood Beautification Graph Layout Through Message Passing, Severino F. Galan, Ole J. Mengshoel

Ole J Mengshoel

Graph layout algorithms are used to compute aesthetic and useful visualizations of graphs. In general, for graphs with up to a few hundred nodes, force-directed layout algorithms produce good layouts. Unfortunately, for larger graphs, they often get stuck at local minima and have high computational complexity. In this paper, we introduce a novel message passing technique for graph layout. The key idea of our message passing technique is that an aesthetic layout can be obtained if each node independently suggests aesthetic placements of its neighbors. In other words, every node sends messages to its neighbors, indicating new and better positions ...


Customized Nonlinear Bandits For Online Response Selection In Neural Conversation Models, Bing Liu, Tong Yu, Ole Mengshoel, Ian Lane 2018 Selected Works

Customized Nonlinear Bandits For Online Response Selection In Neural Conversation Models, Bing Liu, Tong Yu, Ole Mengshoel, Ian Lane

Ole J Mengshoel

Dialog response selection is an important step towards natural response generation in conversational agents. Existing work on neural conversational models mainly focuses on offline supervised learning using a large set of context-response pairs. In this paper, we focus on online learning of response selection in retrieval-based dialog systems.We propose a contextual multi-armed bandit model with a nonlinear reward function that uses distributed representation of text for online response selection. A bidirectional LSTM is used to produce the distributed representations of dialog context and responses, which serve as the input to a contextual bandit. In learning the bandit, we propose ...
