CISL is the research group in which I work at Microsoft. The team brings together systems and machine learning experts, with the vision of having these two disciplines inform each other. This is also the vision for the LearningSys workshop, which was accepted for NIPS 2015, and is co-organized by Markus Weimer from CISL.
If this sounds like your cup of tea, check out the CFP and consider submitting your work.
Also, CISL is hiring: so if this is really your cup of tea, send your resume to me (to the address in top-right corner of my blog); or introduce yourself at the workshop in Montreal.
