14 Oct: Shamsnaz S Virani, Domain Effects on Software
Shamsnaz S Virani, Ph.D., Visiting Research Assistant Professor, UTEP
Investigation of Domain Effects on Software
It is generally accepted that there is very less variability in cohesion, coupling and complexity of software packages within specific domains such as Graphical User Interface (GUI) or Database. This implies that software metrics show low variability within single domain and high variability between domains. This paper investigates the domain issue by creating hierarchical model of four different domains and two software packages within each domain. Metrics are collected on each package and compared against the domains and packages. Results confirm metrics are not domain centric.

21 Oct. Carlos Busso, UT Dallas, on Emotion and Speech. 11:30, room 308
During expressive speech, the voice is enriched to convey not only the intended semantic message but also the emotional state of the speaker. Knowing such emotional states can help adjust system responses so that the user of such a system can be more engaged and have a more effective interaction with the system. Two novel directions in detecting emotional speech are presented: the use of neutral models to detect expressive speech, and Dynamic Bayesian Network (DBN) to model the context and mutual influence in dyadic interaction. Since emotional speech can be regarded as a variation on neutral (non-emotional) speech, it is expected that a robust neutral speech model can be useful in contrasting different emotions expressed in speech. We propose a novel approach to automatically recognize expressive from neutral speech. In this framework, acoustically neutral models are used to measure the degree of similarity between the input speech and the reference neutral models, which is then used as feature for classification. This approach, which was tested with spectral and prosodic features, performs better than conventional classification schemes in terms of accuracy and robustness. Likewise, we propose a Dynamic Bayesian Network (DBN) to explicitly model the conditional dependency between two interacting partners’ emotion states in a dialog and the temporal dynamics of the observed emotion states. With speech based features, the proposed network improves classification accuracy compared to a Gaussian Mixture Model (GMM) baseline on isolated turn-by-turn emotion classification.
23 Oct. Computer Architecture & Networks. 9:30-10:20, room 300B
The Cyber-ShARE Center of Excellence at UTEP, a TeraGrid Campus Champion, invites you to attend an introductory presentation on computer architecture and networks. The goal of this presentation is to cover basic concepts related to modern processor architecture and their impact on software performance. Everybody is welcome to attend, but we ask those planning to attend to please send an RSVP email to raromero2@utep.edu.
28 Oct
30 Oct. MPI Programming Intro - Part I. 9:30-10:20, room 300B
The Cyber-ShARE Center of Excellence at UTEP, a TeraGrid Campus Champion, invites you to participate in a hands-on introduction to MPI programming using computational resources and support available through Cyber-ShARE. This is a two-part workshop to be offered on two consecutive Fridays. Everybody is welcome to attend, but we ask those planning to attend to please send an RSVP email to raromero2@utep.edu.

See description on 30 Oct above.
11 Nov
13 Nov. Intermediate MPI Programming - Part I. 9:30-10:20, room 300B
The Cyber-ShARE Center of Excellence at UTEP, a TeraGrid Campus Champion, invites you to participate in a hands-on workshop on programming parallel applications using basic and intermediate MPIfunctionality. The material to be presented will be useful for applications running on platforms ranging from multicore workstations to clusters to massively parallel machines, i.e., you will be able to run your applications on Cyber-ShARE’s workstations and clusters and on TeraGrid machines. This is a two-part workshop to be offered on two consecutive Fridays. Everybody is welcome to attend, but we ask those planning to attend to please send an RSVP email to raromero2@utep.edu.
18 Nov
20 Nov. Tom Dietterich, Oregon State University, Automated Cleaning of Sensor Network Data using Dynamic Bayesian Networks, 1:40 p.m., Bioscience Research Bldg. room 2.168
In the past, most sensor networks involved a small number of high-quality nodes, and the data recorded from these networks could be manually cleaned and verified before release. New sensor network technology involves large numbers of cheap sensors. The resulting data streams are too voluminous to be manually cleaned. In addition, these cheaper sensors are subject to higher levels of noise and error so there is a greater need to clean the data. We are developing dynamic Bayesian network methods for modeling the joint probability distribution of multiple sensor data streams and then using this model to identify anomalies and errors in the data. The joint probability model discovers and exploits redundancy between sensors and is able to fill in missing values very accurately. We will describe results from the HJ Andrews LTER climate stations and from shorter-term deployments of the SensorScope nodes.
