ShopTalk: A System for Conversational Faceted Search
Gurmeet Manku, James Lee-Thorp, Bhargav Kanagal +11
We present ShopTalk, a multi-turn conversational faceted search system for shopping that is designed to handle large and complex schemas that are beyond the scope of state of the a…
Recency Dropout for Recurrent Recommender Systems
Bo Chang, Can Xu, Matthieu Lê +5
Recurrent recommender systems have been successful in capturing the temporal dynamics in users' activity trajectories. However, recurrent neural networks (RNNs) are known to have d…
Hindrances to precise recovery of cellular forces in fibrous biopolymer networks
Yunsong Zhang, Jingchen Feng, Shay I. Heizler +1
How cells move through the three-dimensional extracellular matrix (ECM) is of increasing interest in attempts to understand important biological processes such as cancer metastasis…
Nonlinear elasticity of disordered fiber networks
Jingchen Feng, Herbert Levine, Xiaoming Mao +1
Disordered biopolymer gels have striking mechanical properties including strong nonlinearities. In the case of athermal gels (such as collagen-I) the nonlinearity has long been ass…
Criticality enhances the reinforcement of disordered networks by rigid inclusions
Jordan L. Shivers, Jingchen Feng, Fred C. MacKintosh
The mechanical properties of biological materials are spatially heterogeneous. Typical tissues are made up of a spanning fibrous extracellular matrix in which various inclusions, s…
Compression stiffening of fibrous networks with stiff inclusions
Jordan L. Shivers, Jingchen Feng, Anne S. G. van Oosten +3
Tissues commonly consist of cells embedded within a fibrous biopolymer network. Whereas cell-free reconstituted biopolymer networks typically soften under applied uniaxial compress…
