International conference on Tools for Artificial Intelligence (ICTAI)

作者： Gang Wang Weifeng Su Xiangye Xiao L. Frederick Department of Computer Science Hong Kong University of Science and Technology Hong Kong China

In this paper, we propose a novel stochastic framework for unsupervised manifold learning. The latent variables are introduced, and the latent processes are assumed to characterize the pairwise relations of points over a high dimensional and a low dimensional space. The elements in the embedding space are obtained by minimizing the divergence between the latent processes over the two spaces. Different priors of the latent variables, such as Gaussian and multinominal, are examined. The Kullback-Leibler divergence and the Bhattachartyya distance are investigated. The latent process model incorporates some existing embedding methods and gives a clear view on the properties of each method. The embedding ability of this latent process model is illustrated on a collection of bitmaps of handwritten digits and on a set of synthetic data

Unlike many efforts that focus on supporting scholarly research by developing large-scale, general resources for a wide range of audiences, we at the Cervantes Project have chosen to focus more narrowly on developing resources in support of ongoing research about the life and works of a single author, Miguel de Cervantes Saavedra (1547-1616). This has lead to a group of hypertextual archives, tightly integrated around the narrative and thematic structure of Don Quixote. This project is typical of many humanities research efforts and we discuss how our experiences inform the broader challenge of developing resources to support humanities research

In the design of vehicles of public transport as much as private, it is important to know the real load properties which are put under the vehicle. Although typical load histories are available, these files were obtained in other countries where the conditions of the ways and the operation of the vehicles are very different. In order to be able to obtain histories of loads in the conditions of our country, a system based on a wireless sensing modules network has been developed to measure deformations, temperature and accelerations in multiple points of the vehicle in real time. The obtained data of each sensor is prepared, processed, stored and transmitted in time intervals towards a receiver, which is in charge to send them to a Internet server for its storage, visualization and analysis for any user connected to the network who have accessibility to the collected information and can make the pertinent procedures and actions. In this work the design of the instrumentation system is based on a wireless sensing modules network and it uses the GPRS protocol which is based on GSM cellular technology, permitting us to send all the data received from each wireless module to the server host.

Computer algorithms commonly involve creation, reorganization or destruction of relations between objects. This means that they are generally excellent candidates for visualization for teaching purposes. For a student to comprehend all the ramifications of certain operations, several different concurrent displays are often required: as well as a visualization of the objects being manipulated by the algorithm, commentary, highlighted source code and various statistics are commonly *** paper describes a strategy for rapidly building animations of algorithms: animations are driven from the source code of the algorithm itself by the addition of animation directives. These directives invoke routines from a toolkit which provides operations commonly needed to display objects and structures. By providing a standard approach to the creation of an animation, creating a new one becomes a straightforward process: many animations in the current collection have been produced by students in one semester *** supporting toolkit contains classes which, in addition to animating basic structure, provide many subsidiary displays - histograms, graphs, etc. which are updated as the algorithm runs. This toolkit has evolved following critical analysis of the features needed to allow easy comprehension of the animated algorithms, for example, a separate commentary area has been abandoned in favour of labels on the animation and 'history' panels have been added to permit simultaneous display of several steps in the algorithm, smaller improvements. Over several years, we have implemented a set of widely referenced algorithm animations commonly taught in data structures and algorithms courses available on the web.

International conference on 3D Imaging, Modeling, Processing, visualization and Transmission (3DIMPVT)

作者： Y. Kamon R. Yamane Y. Mukaigawa T. Shakunaga Department of Computer Science Okayama University Japan

A novel method is proposed for virtual view generation of traditional dances. In the proposed framework, a traditional dance is captured separately for appearance registration and motion registration. By coordinating the appearance and motion data, we can easily control virtual camera motion within a dancer-centered coordinate system. For this purpose, a coordination problem should be solved between the appearance and motion data, since they are captured separately and the dancer moves freely in the room. The present paper shows a practical algorithm to solve it. A set of algorithms are also provided for appearance and motion registration, and virtual view generation from archived data. In the appearance registration, a 3D human shape is recovered in each time from a set of input images after suppressing their backgrounds. By combining the recovered 3D shape and a set of images for each time, we can compose archived dance data. In the motion registration, stereoscopic tracking is accomplished for color markers placed on the dancer. A virtual view generation is formalized as a color blending among multiple views, and a novel and efficient algorithm is proposed for the composition of a natural virtual view from a set of images. In the proposed method, weightings of the linear combination are calculated from both an assumed viewpoint and a surface normal.

Two applications have been evaluated in this paper. The tested 2D moving map application displays the current flight plan together with relevant flight route information. It has Jeppesen chart compliant symbologies for high-enroute and low-enroute flights. All text and symbols are deconflicted. Additional information for chart objects can be obtained on request. Depiction of an own ship symbol is possible in either a track up or north up orientation. Terrain and obstacle data can also be displayed for enhanced situation awareness. The 3D SVS primary flight display provides an egocentric view out of the cockpit window with a depiction of primary flight data as well as a 3D depiction of airports, terrain and obstacles. Navigation procedures can be displayed by a dynamic tunnel-in-the-sky visualizing the selected approach procedure. Traditional chart color coding and Jeppesen symbology is adopted for this 3D display. The 3D depiction is used solely for flight guidance. This paper describes the human factors analysis of flight trials performed with these displays between Centennial, CO and Colorado Springs using a Piper Cheyenne from Marinvent Corp. Six pilots flew the Cheyenne in eighteen flights with completely randomized setups. Two different display concepts were evaluated. One concept under test was the electronic 2D enroute moving map which was compared to classic paper charts on the enroute segment between the two airports.

Background: The completion of the sequencing of human, mouse and rat genomes and knowledge of cross-species gene homologies enables studies of differential gene expression in animal models. These types of studies have the potential to greatly enhance our understanding of diseases such as liver cancer in humans. Genes co-expressed across multiple species are most likely to have conserved functions. We have used various bioinformatics approaches to examine microarray expression profiles from liver neoplasms that arise in albumin-SV40 transgenic rats to elucidate genes, chromosome aberrations and pathways that might be associated with human liver cancer. Results: In this study, we first identified 2223 differentially expressed genes by comparing gene expression profiles for two control, two adenoma and two carcinoma samples using an F-test. These genes were subsequently mapped to the rat chromosomes using a novel visualization tool, the Chromosome Plot. Using the same plot, we further mapped the significant genes to orthologous chromosomal locations in human and mouse. Many genes expressed in rat 1q that are amplified in rat liver cancer map to the human chromosomes 10, 11 and 19 and to the mouse chromosomes 7, 17 and 19, which have been implicated in studies of human and mouse liver cancer. Using Comparative Genomics Microarray analysis (CGMA), we identified regions of potential aberrations in human. Lastly, a pathway analysis was conducted to predict altered human pathways based on statistical analysis and extrapolation from the rat data. All of the identified pathways have been known to be important in the etiology of human liver cancer, including cell cycle control, cell growth and differentiation, apoptosis, transcriptional regulation, and protein metabolism. Conclusion: The study demonstrates that the hepatic gene expression profiles from the albumin-SV40 transgenic rat model revealed genes, pathways and chromosome alterations consistent with experimental and cli

Annual Hawaii International conference on System Sciences (HICSS)

The tools to analyze and visualize information from multiple, heterogeneous sources have often relied on innovations in statistical methods. The results from purely statistical methods, however, overlook relevant semantic features present within natural language and text-based information. Emerging research in ontology languages (e.g. RDF, RDFS, SUO-KIF, and OWL) offers promising avenues for overcoming these limitations by leveraging existing and future libraries of meta-data and semantic mark-up. Using semantic features (e.g. hypernyms, meronyms, synonyms, etc.) encoded in ontology languages, methods such as keyword search and clustering can be augmented to analyze and visualize documents at conceptually richer levels. We present findings from a hierarchical clustering system modified for ontological indexing and run on a topic-centric test collection of documents each with fewer than 200 words. Our findings show that ontologies can impose a complete interpretation or subjective clustering onto a document set that is at least as good as meta-word search.

While most of the existing range image registration algorithms either have to extract and match structural (geometric or optical) features or have to estimate the motion parameters of interest from outliers corrupted point correspondence data for the elimination of false matches in the process of image registration, the registration error and the collinearity error derived directly from the traditional closest point criterion are also capable of doing the same job. However, the latter has an advantage of easy implementation. The purpose of this paper is to investigate which definition of collinearity is more accurate and stable in eliminating false matches inevitably introduced by the closest point criterion. The experiments based on real images show the advantages and disadvantages of different definitions of collinearity.
