Deep Sequential Recommendation for Personalized Adaptive User Interfaces

Harold Soh, Scott Sanner, Madeleine White, Greg Jamieson
2017 Proceedings of the 22nd International Conference on Intelligent User Interfaces - IUI '17  
Specifically, interaction histories are embedded in a learned space along with users and interaction elements; this allows the AUI to query and recommend likely next actions based on similar usage patterns  ...  But this is difficult to achieve with many interaction elements when data-per-user is sparse.  ...  In this respect, the Euclidean space is preferable to dot-product spaces; the search for preferred items reduces to a k-nearest-neighbors (k-NN) search since a u,t+1,j = x u − x j 2 2 + h u,t − x j 2 2  ...

The Role of High-Dimensional Diffusive Search, Stabilization, and Frustration in Protein Folding

Supreecha Rimratchada, Tom C.B. McLeish, Sheena E. Radford, Emanuele Paci
2014 Biophysical Journal  
Proteins explore the conformation space by searching these flat subspaces to find a narrow energetic alley that we call a hypergutter and then explore the next, lower-dimensional, subspace.  ...  Such a framework provides an effective representation of the energy landscape and folding kinetics that does justice to the essential characteristic of high-dimensionality of the search-space.  ...  The intermediate states can be stabilized by both native and nonnative interactions and nonnative interactions can accelerate protein folding by forming intermediates, which partition the search space.  ...
