Kaggle has an interesting competition on gesture recognition from 3d data
if anyone's interested:

   *CHALearn Gesture Challenge*

F. Scott Fitzgerald wrote that "personality is an unbroken series of
successful gestures." Gestures are at the heart of Microsoft's world
record-breaking<http://kaggle.us1.list-manage.com/track/click?u=e4c8fb8b43860678deab268e5&id=493cc3aeb5&e=bf02f945c6>Kinect
system. Our latest competition, the CHALEARN
Gesture Challenge<http://kaggle.us1.list-manage2.com/track/click?u=e4c8fb8b43860678deab268e5&id=25f5e3af17&e=bf02f945c6>,
may just help to convey human personality to the Kinect. Using data from
the Kinect's 3D camera, the challenge is to correctly identify which one of
dozens of gestures matches each data sample from the 3D camera. The goal is
to develop algorithms that can learn to recognize a gesture the first time,
so that, for instance, a person could specify that making a "t" with both
their hands is the gesture to turn their television on.

 The CHALEARN Gesture Challenge is organized by CHALEARN and sponsored in
part by Microsoft. The challenge runs through April 10, 2012. The winning
data scientists will take home $10,000, with an additional twist: Microsoft
may opt to license the winning algorithm for up to $100,000. There's
already a lot of buzz about this competition (see coverage in
Techcrunch<http://kaggle.us1.list-manage1.com/track/click?u=e4c8fb8b43860678deab268e5&id=9baff73783&e=bf02f945c6>

 and the Sydney Morning

).

The competition looks hard at first glance, but the CHALEARN crew have
provided some getting started
tips<http://kaggle.us1.list-manage.com/track/click?u=e4c8fb8b43860678deab268e5&id=82101fd0db&e=bf02f945c6>
on
the forum.  Our President and Chief Scientist, Jeremy Howard, has written
more about the background behind this competition, and its
applications, in this
article<http://kaggle.us1.list-manage1.com/track/click?u=e4c8fb8b43860678deab268e5&id=5775a85367&e=bf02f945c6>

*The Accidental Scientist*

Jeremy has just been featured by Wired
Magazine<http://kaggle.us1.list-manage.com/track/click?u=e4c8fb8b43860678deab268e5&id=6432b3ad22&e=bf02f945c6>,
which dubbed him “The Accidental Scientist”. In the article, Jeremy
outlines what he believes is necessary to compete successfully on
Kaggle (*"great
creativity, great open-mindedness, prototyping, many iterations"*). Other
notable Kagglers are interviewed in the piece, including the members of the
Mapping Dark Matter winning team
*DeepZot*<http://kaggle.us1.list-manage1.com/track/click?u=e4c8fb8b43860678deab268e5&id=3519c0125f&e=bf02f945c6>,
and *Momchil Georgiev*<http://kaggle.us1.list-manage1.com/track/click?u=e4c8fb8b43860678deab268e5&id=54e5411632&e=bf02f945c6>,
who is currently in the top-10 of two active competitions.

 The piece quotes Michael Chui of McKinsey & Company, who talks about how
hard it can be for companies to find staff with a talent for handling data.
Kaggle makes finding talent easier: both Jeremy and Ben

started
out as top Kagglers. As a gentle reminder, we're currently hiring
developers and data
scientists<http://kaggle.us1.list-manage1.com/track/click?u=e4c8fb8b43860678deab268e5&id=bc19f0e154&e=bf02f945c6>
and
we're giving automatic interviews to anyone with a top-10 finish in a
Kaggle competition. We'd love to hear from you.

  *Rules and ToS*

We have made a slight change to the Terms and
Conditions<http://kaggle.us1.list-manage.com/track/click?u=e4c8fb8b43860678deab268e5&id=810cafc76b&e=bf02f945c6>
 adding 3.6:

*No individual or entity may share solutions or code for any competition,
or collaborate in any way, with any other individual or entity that is
participating as a separate individual or entity for the same competition.
The foregoing shall not apply to any public communications, such as forum
participation or blog posts.*

We are also aware that the rules haven't been as clear as we might have
liked. From now on, before you download the data for any new competition,
you will be reminded that:

   - you cannot sign up to Kaggle from multiple accounts and therefore you
   cannot submit from multiple accounts; and
   - privately sharing code or data is not permitted outside of teams
   (sharing data or code is permissible if made available to all players, such
   as on the forums).

We've reached out to several teams about this issue. Please let us know
ASAP if you have multiple accounts and we've not reached out to you.
