  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 weighted random oversamping (WRoS) technique and a PATOP² algorithm which makes an exploration-exploitation tradeoff, our proposed CV approach offers a unified solution to two typical yet disparate needs: reinforce obscure truth and discover hidden truth.

• [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 work 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.

  The most commonly used auctions for 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, applying all-pay auctions to crowdsourcing, as this paper does, gains several advantages over winner-pay auctions, and reaps much higher profit with an adaptive prize.

  Despite that crowdworkers are heterogeneous in their "types" (abilities, costs, etc.) as we all know, the hardness to model and analyze it has restricted researchers to adopt a homogeneous model where all the workers' types are assumed to follow a (single) common Bayesian belief. This paper proposes an asymmetric all-pay auction model to characterize the heterogeneity, and uses a prize tuple to achieve an interesting and counter-intuitive property called Strategy Autonomy (SA).

  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 Tullock contests as an alternative mechanism that is more appealing to "ordinary" participants. Tullock contests distinguish themselves from auctions in its imperfectly discriminating property: "You always have a chance to win, no matter how 'weak' you are." This feature is particularly desirable for, e.g., micro-task crowdsourcing (such as crowd sensing).

  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.
