Dr. Shu-Ching Chen is a Professor in the Knight Foundation School of Computing and Information Sciences (KFSCIS) at Florida International University (FIU), Miami. He has been a Full Professor since August 2009 in SCIS at FIU. Prior to that, he was an Assistant/Associate Professor in SCIS at FIU from 1999. He received his Ph.D. degree in Electrical and Computer Engineering in 1998, and Master's degrees in Computer Science, Electrical Engineering, and Civil Engineering in 1992, 1995, and 1996, respectively, all from Purdue University, West Lafayette, IN, USA.
As the Director of the Distributed Multimedia Information Systems Laboratory at SCIS, Dr. Chen has worked with undergraduate and graduate students on the design, implementation, and maintenance of challenging, far-reaching, and community-centered projects.
Dr. Chen is the Co-PI and leader of the Computer Science Component of the Florida Public Hurricane Loss Model (FPHLM), a large-scale hurricane catastrophe model developed by a multi-disciplinary team of experts in the fields of meteorology, wind and structural engineering, computer science, GIS, statistics, finance, and actuarial science. It is the first public hurricane loss model in the world. The realization of this innovative project involves the close collaboration of multiple academic and scientific institutions, of which Florida International University is the leading institution.
The state of Florida ranks number one in total insured property value exposed to hurricane wind. Out of Florida's $3.6 trillion in insured properties, about $2 trillion are residential, and all are exposed to hurricane risk. This reality gave birth to this project. Funded by the Florida Office of Insurance Regulation (FL OIR), the FPHLM was born out of the need of accurately assessing hurricane wind risk and predicting insured losses for the Floridians' residential properties. Since the release of its first version in March of 2006 (see press release), the model has been used over 2,600 times by the state and over 200 times by firms in the insurance industry. As an open project, which undergoes a strict certification process every two years, the FPHLM provides the state regulators a reliable benchmark in the homeowner insurance market and allows them to better formulate the state's homeowner insurance rate-making policy. The FPHLM's impact on the community is unquestionable, as its predictions directly influence the home insurance rates payed by Floridians every month.
The model consists of three major components: wind hazard (meteorology), vulnerability (engineering), and insured loss cost (actuarial). It has over a dozen sub-components. The computer platform is designed to accommodate future hookups of additional sub-components or enhancements.
The FPHLM estimates loss costs and probable maximum loss levels from hurricane events for personal lines and commercial lines of residential property. The losses are estimated for building, appurtenant structures, contents, and additional living expenses.
In essence, the FPHLM is a complex collection of computer programs that simulate and predict how, where and when hurricanes form, their wind speeds, intensity and sizes, their tracks, how they are affected by the terrain after landfall, how the winds interact with different types of structures, how much damage they can cause to house roofs, windows, doors, and interiors, how much it will cost to rebuild the damaged parts, and how much of the loss will be paid by insurers.
Florida also ranks number one in coastal property exposed to storm surge. In the face of this reality, in 2013 the state funded FIU to enhance the FPHLM by adding both a storm surge component and an inland flooding component. The proposed new model will assess storm surge and hurricane-related rain flood risk and estimate both the insured and uninsured losses that they may cause. The enhancement project will take three years with $4.5 million funding from the State.
More information on the FPHLM is available on the project's web site.

Miami-Dade County is particularly susceptible to storm surges caused by hurricanes. To help Miami-Dade county residents understand the dangers of storm surge, hydrological and software development experts at FIU's International Hurricane Research Center (IHRC) and College of Engineering and Computing (CEC) teamed up with Miami-Dade County to create a Storm Surge Simulator, a web-based application that allows users to visualize the potential storm surge effects on their home or business.
Dr. Chen led the development team of Computer Science students to combine cutting-edge web technologies with storm surge modeling output in order to help the Miami-Dade community.
The result of the paper A Progressive Morphological Filter for Removing Non-Ground Measurements from Airborne LIDAR Data, authored by Dr. Chen and his colleagues K. Zhang, D. Whitman, M.-L. Shyu, J. Yan, and C. Zhang, and published in IEEE Transactions on Geoscience and Remote Sensing, vol. 41, issue 4, pp. 872-882, April 2003, was used by the official Miami-Dade County Storm Surge Simulator project.

Thanks to the availability of mobile devices, emergency responders, supporting agencies and even private citizens can capture imagery of disaster events as they unfold. Once the crisis is contained, however, it's a daunting task for emergency managers to collect, organize and integrate disaster event data from multiple sources into incidence command systems where situation reports, incidence action plans, etc. are being held. Therefore, Dr. Chen's group has developed a semi-autonomous system, the Multimedia-Aided Disaster Information Integration System (MADIS), that uses advanced data integration and visual analysis techniques to associate temporal, spatial and other textual features of a disaster event situation report with event images and related text annotations.
The system is developed on Apple's mobile operating system (iOS) and runs on iPad tablets, and it is evaluated by domain experts from the local emergency management department. By interacting with the Miami-Dade Emergency Management (MDEM) personnel through evaluation and exercise activities, the system is constantly being updated by improving user interface experience and back-end support techniques. Feedback from our collaborative partners at MDEM and the potential users suggests that our system will be very useful for emergency managers to gain insight of the situation at the actual disaster scene and to respond swiftly. It is also encouraged to further develop the system into an operational pilot and promote the commercialization of the system for benefiting the whole Emergency Management community.
The system, developed as part of the project A Data Mining Framework for Enhancing Emergency Response Situation Reports with Multi-Agency, Multi-Partner, Multimedia Data, received funding from the Visual Analytics for Command, Control, and Interoperability Environments (VACCINE), the Department of Homeland Security's (DHS) Center of Excellence in Visual and Data Analytics, which was established in July of 2009.

Dr. Chen's Business Continuity Information Network (BCIN) project is the first web-based Public-Private Partnership tool that helps the County Business Recovery Program communicate, share information, and collaborate on disaster events with the private sector.
By tracking the status of critical services over multiple counties, the BCIN helps businesses to better assess the impact of a disaster on the community and find resources to recover faster after a disaster. Additionally, it provides a gathering place for businesses to report on the available resources (products/services) they can provide, and helps county partners collect damage report data from county and company sources in order to understand the amount of damage in the business community immediately after a disaster event.
The role of the BCIN in the success of businesses is invaluable. Studies show that about 40% of the companies that closed for three or more days as a result of a hurricane failed within 36 months. If the BCIN helped 5% of the companies in South Florida to speed up their hurricane recovery by one week, it would prevent $220 million of non-property economic losses that would result from that week's closure.
Many businesses have already joined the Network. Some of the participating businesses are listed below:
Since its release, the BCIN has been actively used in many community activities, some of which are listed below:
Dr. Chen has received multiple recognitions as his role has been critical for the success of the BCIN.
The development and implementation of the Business Continuity Information Network (BCIN) has provided the [Miami-Dade County's Business Recovery] program with a key tool necessary to carry out many of its critical functions including real-time data collection and gathering. BCIN is quickly becoming a nationally recognized information sharing tool for use by public-private collaborative programs ... FIU's contribution to the success of Miami-Dade County's Business Recovery Program is truly immeasurable. (Read recognition letter).

Dr. Chen's work on the Coordinated Damage Assessment Application (CDAA) is a reinterpretation of Miami-Dade County's SnapShot Damage Assessment Application.
The CDAA has been made available to the residents of Miami-Dade County, and has assisted in providing accurate situational awareness regarding the impact of a disaster as well as has helped emergency responders plan an appropriate response and recovery.
The CDAA is composed of two components: a public page and a private administration web application, both of which were powered by an application called Snapshot, which was officially used by the Miami-Dade Department of Emergency Management (DEM).
The CDAA is implemented with shared codebase to eliminate as much platform-specific code as possible, modularized code for organized and easily visualized application structure, and lightweight frameworks to abstract several developmental processes. It provides support for assessing either online or offline via PCs, laptops, tablets, and smartphones, and provides an aggregated view of the impact of the disaster.
The goals of this application are to leverage on the community's altruism, provide the community a role and leave them situationally aware, streamline impact assessments, rapidly gather disaster impact information, and efficiently plan for a response and recovery.
From the community's point of view, the CDAA's main roles are to simplify the assessment process for the affected properties and to provide feasible channels for having assessments. On the other hand, the CDAA is implemented for government officials to quickly update the assessment process and to support the ability to easily view and utilize aggregated impact results.
In the paper Affinity Hybrid Tree: An Indexing Technique for Content-Based Image Retrieval in Multimedia Databases published in Proceedings of the IEEE International Symposium on Multimedia (ISM2006), pp. 47-54, December 11-13, 2006, San Diego, CA, USA, Dr. Chen and his PhD student Kasturi Chatterjee proposed the Affinity Hybrid Tree (AH-Tree), a novel indexing and access method to organize large image data sets efficiently and to support popular image access mechanisms like Content-Based Image Retrieval (CBIR) by embedding the high-level semantic image-relationship in the access mechanism as it is.
The AH-Tree combines SpaceBased and Distance-Based indexing techniques to form a hybrid structure that is efficient in terms of computational overhead and fairly accurate in producing query results close to human perception.
The proposed index structure solves the existing problems of introducing high-level image relationships in a retrieval mechanism without going through the pain of translating the content-similarity measurement into feature-level equivalence and yet maintaining an efficient structure to organize the large sets of images.
The paper won the Best Paper Award.
In the paper A Novel Anomaly Detection Scheme Based on Principal Component Classifier, published in Proceedings of the IEEE Foundations and New Directions of Data Mining Workshop, in conjunction with the Third IEEE International Conference on Data Mining (ICDM'03), pp. 172-179, November 19-22, 2003, Melbourne, Florida, USA., Dr. Chen and his colleagues Dr. Mei-Ling Shyu, Dr. Kanoksri Sarinnapakorn, and Dr. LiWu Chang, proposed a novel scheme that uses robust principal component classifier in instrusion detection problems where the training data may be unsupervised.
Assuming that anomalies can be treated as outliers, they constructed an intrusion predictive model from the major and minor principal components of the normal instances. A measure of the difference of an anomaly from the normal instance is the distance in the principal component space. In the paper, they showed that the distance based on the major components that account for 50% of the total variation and the minor components whose eigenvalues are less than 0.20 work well.
They also showed that experiments with KDD Cup 1999 data demonstrated that the proposed method achieves 98.94% in recall and 97.89% in precision with the false alarm rate 0.92%, and outperforms the nearest neighbor method, density-based local outliers (LOF) approach, and the outlier detection algorithm based on Canberra metric.

In the paper Video Semantic Event/Concept Detection Using a Subspace-Based Multimedia Data Mining Framework, published in IEEE Transactions on Multimedia, Special Issue on Multimedia Data Mining, Volume 10, Number 2, pp. 252-259, February 2008, Dr. Chen, together with his colleagues and students, proposed a subspace-based multimedia data mining framework for video analysis, specifically video event/concept detection, by addressing two basic issues: semantic gap and rare event/concept detection.
The proposed framework achieves full automation via multimodal content analysis and intelligent integration of distance-based and rule-based data mining techniques. The content analysis process facilitates the comprenhensive video analysis by extracting low-level and middle-level features from audio/visual channels. The integrated data mining techniques effectively address these two basic issues by alleviating the class imbalance issue along the process, and by reconstructing and refining the feature dimension automatically.
The promising experimental peformance on goal/corner event detection and sports/commercials/building concepts extraction from soccer videos and TRECVID news collections demonstrates the effectiveness of the proposed framework.
Additionally, the framework's unique domain-free characteristic indicates the great potential of extending it to a wide range of different application domains.
TRECVID is one of the most famous international video retrieval competitions, conducted by the National Institute of Standards and Technology (NIST), and has held a total of 15 competitions taking place annually since the year 2003. The Ad-hoc Video Search (AVS) task requests the participants to build a video retrieval system within a one-month period, capable of searching for thirty types of videos in a large-scale database. Each type of the videos is described by a query, such as "Find shots of a projection screen" and "Find shots of a truck standing still while a person is walking beside or in front of it."
In the proposed framework, the most recent advances in video processing and deep learning are utilized to understand the contents of the videos. The results outperformed those of several recognized research groups. The development of this system can potentially promote the search engine's capability to understand general descriptions of the video's content without relying on user-created text metadata.
The proposed work won the third place in TRECVID 2018 (AVS task). The FIU News article detailing this achivement can be found here.
