Biosketch:

I conduct research on Internet of Things (IoT) security, adversarial machine learning, and artificial intelligence (AI)-empowered IoT applications. My objectives are to safeguard IoT systems against vulnerabilities, make machine-learning algorithms robust to adversarial and unreliable behaviors, and develop innovative AIoT applications with profound economic and societal impact. Prior to joining Missouri S&T, I was a Program Lead and Scientist at A*STAR. I earned my Ph.D. in electrical and computer engineering from the National University of Singapore. I am an IEEE Senior Member.

Teaching

  • CS5001:

    Internet of Things with Applied Data Science

     (Spring 2020)
    Auditing students: sign up (no more slots now)

  • CS6001:

    Internet of Things with Data Science

    (Fall 2020) - Open for Enrollment!
    Class time: Mon & Wed, 4:00-5:15 PM
    This course is a successor to my CS5001 course in spring (above) but will NOT be a duplicate. While essentials and fundamentals will (and should) remain, I will introduce a substantial amount of new, research-oriented contents to this course to gear it at the 6000 level. In particular, I will create a refined list of intriguing research topics across the areas of IoT, security, and machine learning, and spend a good amount of time with students discussing representative papers in the field. Besides technical contents, I will also cultivate students' analytical and critical thinking abilities as well as scientific writing and presentation skills, which are crucial to developing and honing your research caliber.

    IEEE Internet of Things Journal (IoT-J), vol. 6, no. 3, pp. 5651-5664, June 2019.
    We propose a cross validation (CV) approach which seeks a validating crowd to ratify the contributing crowd in terms of the quality of sensor data contributed by the latter. Using a WRoS technique and a PATOP2 algorithm which makes an exploration-exploitation tradeoff, the CV approach offers a unified solution to two typical yet disparate needs: reinforce obscure truth and discover hidden truth. (See illustration.)

  • [ICC'18] Distributed anomaly detection using autoencoder neural networks in WSN for IoT [pdf] [slides] [DOI: 10.1109/ICC.2018.8422402]
    T. Luo and S. Nagarajan
    IEEE International Conference on Communications (ICC), May 2018.
    This paper is the first that introduces autoencoder neural networks (ANN), a deep learning model, into wireless sensor networks (WSN) to detect anomalies. It contradicts the general belief that "deep learning is not suitable for WSN", by (1) making deep learning (extremely) shallow and (2) allocates computation load to sensors and IoT cloud using a two-part algorithm, DADA-S and DADA-C. (See illustration.)

    IEEE Communications Magazine, vol. 55, no. 3, pp. 68-74, March 2017.
    This survey paper provides a technical overview and analysis of six incentive mechanism design frameworks: auction, lottery, trust and reputation system, bargaining game, contract theory, and market-driven mechanism.
  • [TIST'16] Incentive mechanism design for crowdsourcing: an all-pay auction approach [ACM Lib] [pdf] [DOI: 10.1145/2837029]
    T. Luo, S. K. Das, H-P. Tan, and L. Xia
    ACM Transactions on Intelligent Systems and Technology (TIST), vol. 7, no. 3, pp. 35:1-26, February 2016.
    The most common auctions used in incentive mechanism design are winner-pay auctions, where only winners (i.e., highest bidders who will receive reward) need to pay for their bids (by money or effort). In contrast, all-pay auctions require every bidder to pay regardless of who wins, which sounds rather unreasonable. However, we show that applying all-pay auctions to crowdsourcing makes perfect sense and gains several advantages over winner-pay auctions. (This paper builds on our INFOCOM'14 paper.)
  • [TMC'16] Incentive mechanism design for heterogeneous crowdsourcing using all-pay contests [pdf] [DOI: 10.1109/TMC.2015.2485978]
    T. Luo, S. S. Kanhere, S. K. Das, and H-P. Tan
    IEEE Transactions on Mobile Computing (TMC), vol. 15, no. 9, pp. 2234-2246, September 2016.
    Despite that crowdworkers are typically heterogeneous (in terms of "types" such as abilities, costs, etc.), the daunting challenge of modeling and analyzing it has restricted researchers to homogeneous models in which all the worker types follow a single, common distribution (Bayesian belief). This paper addresses this challenge using an asymmetric all-pay auction model with a prize tuple. In addition, a most interesting Strategy Autonomy (SA) phenomenon is discovered.
  • [INFOCOM'15] Crowdsourcing with Tullock contests: A new perspective [pdf] [DOI: 10.1109/INFOCOM.2015.7218641]

    The 34th IEEE International Conference on Computer Communications (INFOCOM), April 2015, pp. 2515-2523.
    Best Paper Award nominee
    What is a Tullock contest? Think it as a lucky draw! While auctions have dominated the realm of mechanism design for decades, this paper suggests that Tullock contests is a better alternative in that it is more "friendly" to ordinary participants ("grass roots"): You always have a chance to win, no matter how 'weak' you are.
  • [TMC'15] Quality of contributed service and market equilibrium for participatory sensing [pdf] [DOI: 10.1109/TMC.2014.2330302]
    C-K. Tham and T. Luo
    IEEE Transactions on Mobile Computing (TMC), vol. 14, no. 4, pp. 829-842, April 2015.
    In order to characterize QoS for crowdsensing, this work proposes a metric called Quality of Contributed Service (QCS) which aggregates individual quality of contributions and takes into account information quality and time sensitivity. QCS is then analyzed using a market based supply-and-demand model.
  • [INFOCOM'14] Profit-maximizing incentive for participatory sensing [pdf] [Much enhanced version: ACM TIST'16]

Systems Work

Besides theory, I am also keen in developing real systems. I worked with team to have developed the following mobile crowdsourcing / crowdsensing applications, which are freely downloadable at Apple Store and Google Play. The latest software update was in 2018.
