In his dissertation titled “Design and Development of Real-Time Big Data Analytics Frameworks,Dr. Solaimani focused on two areas: anomaly detection on structured VMware performance data (e.g., CPU/Memory usage metric, etc.) and text mining for politics in unstructured text data. Dr. Solaimani developed real-time distributed frameworks with ML and NLP techniques.  With regard to anomaly detection, Dr. Solaimani implemented an adaptive clustering technique to identify individual anomalies and a Chi-square-based statistical technique to detect group anomalies in real-time. With regards to text mining, Dr. Solaimani developed a real-time framework, SPEC, to capture online news articles in different languages from the web and annotated them using CoreNLP, PETRARCH, and CAMEO dictionary to generate structured political events such as in ‘who-did-what-to-whom’ format. Later, Dr. Solaimani extended this framework to code atrocity events – involving machine-coded, structured data containing perpetrators, action, victims, etc. Finally, Dr. Solaimani developed a novel, distributed, window-based political actor-recommendation framework to discover and recommend new political actors with their possible roles. Dr. Solaimani’s research interests focus on machine learning using Big Data. Currently, he is a Senior Application Architect at Blue Cross and Blue Shield of Illinois, Montana, New Mexico, Oklahoma & Texas, based in Dallas, Texas, where he is designing and leading a team for Data Lake with real-time streaming using cutting edge Big Data technologies.
  • Dr. Kenneth Joseph Platz received his PhD during the fall of 2017 under the guidance of Dr. S. Venkatesan. In his dissertation titled “Saturation in Lock-Based Concurrent Data Structures,” Dr. Platz developed two variants of existing lock-based concurrent data structures, a linked list and a skiplist. He then demonstrated how one can unroll these data structures to support multiple keys per node. This was followed by demonstrating how lock-based data structures can saturate, or plateau in performance, at sufficiently high thread counts, depending upon the percentage of write operations applied to that data structure. Dr. Platz then discussed how one can apply a new technique involving group mutual exclusion to provide a lock-based data structure that is resilient to saturation. Platz demonstrated how this technique can be applied to the implementations of linked lists and skiplists to provide the scalable performance to 250 threads and beyond. Dr. Platz’s research interests include concurrent data structures, their memory management techniques, and transactional memory systems. During his time at UT Dallas, he developed and presented computer science classes to high school students as part of UT Dallas’ K-12 CS Outreach Program.

  • Dr. Yasmeen Alufaisan received her PhD under the guidance of Dr. Murat Kantarcioglu during the summer of 2018. Dr. Alufaisan’s research interests include Data Mining and Transparency. In her dissertation titled “Towards Algorithmic Accountability in Data Mining,” Dr. Alufaisan focused on four desired aspects of accountability in data mining.  These aspects are: reliability, discrimination-awareness, transparency, and privacy. Dr. Alufaisan explains, “We first investigate the reliability of using data mining techniques to predict various individual traits.  We then measure the impact of various adversarial attacks on the prediction accuracy of data mining models. We also propose countermeasures that can reduce the effectiveness of these attacks. Secondly, we develop two techniques to measure discrimination of a black-box model (i.e., without knowing the data mining model details) as a result of data bias or algorithmic weakness. Data bias is investigated further by introducing artificial bias to the dataset under consideration. After that, we develop transparency models to help unmask the incomprehensible reasoning made by any data mining\machine learning models. We look into the transparency of both white-box (i.e., when we know the model details) and black-box machine learning models. For white-box transparency, we propose an Instance-based Transparency model (IT) that provides simple explanations by using a novel rule selection technique. For the black-box transparency, we introduce the Reverse Engineering Approximate Learning (REAL) Model that outputs a decision tree to interpret any black-box classifier. Finally, we extensively study the trade-off between privacy and transparency. We introduce a novel privacy model that can prevent the inference of individuals’ sensitive information when disclosing a transparency model.” Her research with Dr. Murat Kantarcioglu has been published in various conference publications and journals including Pacific-Asia Conference on Advances in Knowledge Discovery and Data Mining (PAKDD’18), IEEE International Conference on Collaboration and Internet Computing (CIC 2017 & 2016), IEEE International Conference on Intelligence and Security Informatics (ISI’17), Pacific-Asia Conference on Advances in Knowledge Discovery and Data Mining (PAKDD’18), and more.

  • Dr. Saifeng Ni obtained her PhD during the summer of 2018 while working under the supervision of Dr. Xiaohu Guo in the Computer Graphics and Animation Lab. In her dissertation titled, Variational Volumetric Meshing,” Dr. Ni discussed variational-based methods to help tackle mesh generation problems, i.e., within an energy-optimization framework. An energy that inhibits small heights is proposed to suppress almost all badly-shaped elements in tetrahedral meshing. By iteratively optimizing vertex positions and mesh connectivity, slivers are harshly suppressed even in anisotropic tetrahedral meshing. In addition, a particle-based field alignment framework is introduced. Especially, a Gaussian Hole Kernel is constructed and associated with each particle to constrain the formation of the desired one-ring structure aligned with the frame field. The minimization of the sum of Gaussian hole kernels induces an inter-particle potential energy whose minimization encourages particles to have the desired layout. A cubic one ring structure leads to high-quality, hexahedral-dominant meshing. The one-ring structures of the BCC and FCC lattice lead to high-quality, field-aligned tetrahedral meshing. This is the first time both Riemannian distance alignment and direction alignment problem have been considered in tetrahedral meshing. Also, field-aligned, tetrahedral meshing better preserves the rotation geometry and also creates better anisotropic meshes.  Dr. Ni has had her research published in various conferences and journals publications including the Eurographics Symposium on Geometry Processing (SGP’18), International Conference on Geometric Modeling and Processing 2017 (GMP’17), 7th International ICST Conference, (WICON’13), IEEE Vehicular Technology Conference (VTC’11), and more. Over the summer, Dr. Ni took part in an internship at Samsung Research America (SRA) in Dallas, Texas, where she has been working on 3D Face Reconstruction. During one of their research competitions, Dr. Ni received best poster award (3rd place). Dr. Saifeng Ni is currently working at Samsung Research America as a Senior Research Engineer.
