I'm the tutorials chair for the 2014 SIAM conference on data mining (SDM) (for readers not aware of the data mining landscape, SDM is a SODA-style data mining conference run by SIAM - i.e it's a CS-style venue with peer-reviewed papers, rather than a math-style conference like SIAM discrete math). SDM is one of the major venues for data mining research, especially the more statistically focused kind. It will be held in Philadelphia between Apr 24-26, 2014.
SDM runs 4-5 tutorials each year on various aspects of data mining (ranging from theory/algorithms to specific application areas). I'm personally very interested in encouraging submissions from people in the theory community working with data who might want to share their expertise about new methods/techniques from theoryCS land with the larger data analysis community.
The deadline is Oct 13, and all you need is a few pages describing the tutorial content, target audience, and some sample material (more details here). If you have an idea and are not sure whether it will fit, feel free to email me directly as well.
