Cognition as a Service, Levy on NSA, SD-Sized Computer, and Learning Research

  1. Launching the Wolfram Connected Devices Project — Wolfram Alpha is cognition-as-a-service, which they hope to embed in devices. This data-powered Brain-in-the-Cloud play will pit them against Google, but G wants to own the devices and the apps and the eyeballs that watch them … interesting times ahead!
  2. How the USA Almost Killed the Internet (Wired) — “At first we were in an arms race with sophisticated criminals,” says Eric Grosse, Google’s head of security. “Then we found ourselves in an arms race with certain nation-state actors [with a reputation for cyberattacks]. And now we’re in an arms race with the best nation-state actors.”
  3. Intel Edison — SD-card sized, with low-power 22nm 400MHz Intel Quark processor with two cores, integrated Wi-Fi and Bluetooth.
  4. N00b 2 L33t, Now With Graphs (Tom Stafford) — open science research validating many of the findings on learning, tested experimentally via games. In the present study, we analyzed data from a very large sample (N = 854,064) of players of an online game involving rapid perception, decision making, and motor responding. Use of game data allowed us to connect, for the first time, rich details of training history with measures of performance from participants engaged for a sustained amount of time in effortful practice. We showed that lawful relations exist between practice amount and subsequent performance, and between practice spacing and subsequent performance. Our methodology allowed an in situ confirmation of results long established in the experimental literature on skill acquisition. Additionally, we showed that greater initial variation in performance is linked to higher subsequent performance, a result we link to the exploration/exploitation trade-off from the computational framework of reinforcement learning.
