Frenzy: A Platform for Friendsourcing

Although micro-task crowdwork was popularized by the Mechanical Turk (MTurk) labor-market platform, it is useful in many other contexts and communities as well. Unfortunately, several MTurk design choices, such as worker anonymity and isolation, are problematic in other environments. This paper introduces Frenzy, a platform for friendsourcing. Frenzy helps people who are closely connected in a ...

Coding of faded scene transitions

Coding of a scene transition is often a challenging problem, from compression efficiency point of view, because motion compensation may not be a powerful enough method to represent changes between pictures in the transition. This paper proposes a overlay coding technique for coding faded scene transitions. As shown by extensive simulations, over 50% bit-rate savings in both cross-fades and thro...

Kalman filtering with faded measurements

This paper considers a sensor network where single or multiple sensors amplify and forward their measurements of a common linear dynamical system (analog uncoded transmission) to a remote fusion center via noisy fading wireless channels. We show that the expected error covariance (with respect to the fading process) of the time-varying Kalman filter is bounded and converges to a steady state va...

Disability And The Managed Care Frenzy: A Cautionary Note

Parallel mining of time-faded heavy hitters

We present PFDCMSS, a novel message–passing based parallel algorithm for mining time–faded heavy hitters. The algorithm is a parallel version of the recently published FDCMSS sequential algorithm. We formally prove its correctness by showing that the underlying data structure, a sketch augmented with a Space Saving stream summary holding exactly two counters, is mergeable. Whilst mergeability o...
