Deconvolving Feedback Loops in Recommender Systems

Ayan Sinha, David F. Gleich, Karthik Ramani
In Proceedings of the Thirtieth Annual Conference on Neural Information Processing Systems (NIPS'16) , Barcelona, Spain, 2016

Collaborative filtering is a popular technique to infer users' preferences on new content based on the collective information of all users preferences. Recommender systems then use this information to make personalized suggestions to users. When...

Window-Shaping: 3D Design Ideation in Mixed Reality

Ke Huo, Vinayak, Karthik Ramani
In Proceedings of the 2016 Symposium on Spatial User Interaction, Tokyo, Japan, 2016 Oct.

We present, Window-Shaping, a mobile, markerless, mixed-reality (MR) interface for creative design ideation that allows for the direct creation of 3D shapes on and around physical objects. Using the sketch-and-inflate scheme, we present a design...

Deep Learning 3D Shape Surfaces using Geometry Images

Deep Learning 3D Shape Surfaces using Geometry Images

Ayan SInha, Jing Bai, Karthik Ramani
The 14th European Conference on Computer Vision, October 11-14, 2016, Amsterdam, The Netherlands.

Surfaces serve as a natural parametrization to 3D shapes. Learning surfaces using convolutional neural networks (CNNs) is a challenging task. Current paradigms to tackle this challenge are to either adapt the convolutional filters to operate on...

Proto-TAI++: Exploring perceptually consistent creation of planar shape assemblies through multi-modal tangible interactions

Cecil Piya, Vinayak, Karthik Ramani
Journal of Computing and Information Science in Engineering, Volume 16, Issue 3, September 2016

We explore tangible 3D interactions that allow for geometric and perceptual correspondence between a midair modality and the 3D elements it controls. To demonstrate our approach, we use a concrete application scenario through Proto-TAI++, a...
