- June 18, 2012: I'm at CVPR 2012!
- I'm at CVPR 2012, and I'd love to meet you! Come to our demo on computing face attributes live and doing advanced multi-attribute similarity searches (Monday, Demo Booth #6, all day concurrent with the posters), and our poster on calibrating multiple attribute values using Multi-Attribute Spaces (Wednesday 2nd Poster session 3B, 1:30-3:30, #4).
