- Apple Patent on Learning-based Estimation of Hand and Finger Pose — machine learning to identify gestures (hand poses) that works even when partially occluded. See writeup in Apple Insider.
- The Internet of Kafkaesque Things (ACLU) — As computers are deployed in more regulatory roles, and therefore make more judgments about us, we may be afflicted with many more of the rigid, unjust rulings for which bureaucracies are so notorious.
- Schmidt and Hunter (1998): Validity and Utility of Selection Methods in Personnel (PDF) — On the basis of meta-analytic findings, this article examines and summarizes what 85 years of research in personnel psychology has revealed about the validity of measures of 19 different selection methods that can be used in making decisions about hiring, training, and developmental assignments. (via Wired)
- Complete Force Control in Constrained Under-actuated Mechanical Systems (Robohub) — Nori focuses on finding ways to advance the dynamic system of a robot – the forces that interact and make the system move. Key to developing dynamic movements in a robot is control, accompanied by the way the robot interacts with the environment. Nori talks us through the latest developments, designs, and formulas for floating-base/constrained mechanical systems, whole-body motion control of humanoid systems, whole-body dynamics computation on the iCub humanoid, and finishes with a video on recent implementations of whole-body motion control on the iCub.

Tips on how to build effective human-machine hybrids, from crowdsourcing expert Adam Marcus.
In a recent O’Reilly webcast, “Crowdsourcing at GoDaddy: How I Learned to Stop Worrying and Love the Crowd,” Adam Marcus explains how to mitigate common challenges of managing crowd workers, how to make the most of human-in-the-loop machine learning, and how to establish effective and mutually rewarding relationships with workers. Marcus is the director of data on the Locu team at GoDaddy, where the “Get Found” service provides businesses with a central platform for managing their online presence and content.
In the webcast, Marcus uses practical examples from his experience at GoDaddy to reveal helpful methods for how to:
- Offset the inevitability of wrong answers from the crowd
- Develop and train workers through a peer-review system
- Build a hierarchy of trusted workers
- Make crowd work inspiring and enable upward mobility
What to do when humans get it wrong
It turns out there is a simple way to offset human error: redundantly ask people the same questions. Marcus explains that when you ask five different people the same question, there are some creative ways to combine their responses, and use a majority vote. Read more…
