Constrained LQR for Low-Precision Data Representation [PDF]
Performing computations with a low-bit number representation results in a faster implementation that uses less silicon, and hence allows an algorithm to be implemented in smaller and cheaper processors without loss of performance.

Mining Actuarial Risk Predictors in Accident Descriptions Using Recurrent Neural Networks
One crucial task of actuaries is to structure data so that observed events are explained by their inherent risk factors. They are proficient at generalizing important elements to obtain useful forecasts.

Voxel selection in fMRI data analysis based on sparse representation [PDF]
Multivariate pattern analysis approaches toward detection of brain regions from fMRI data have been gaining attention recently. In this study, we introduce an iterative sparse-representation-based algorithm for detection of voxels in functional MRI (fMRI)

Multiple Graph Regularized Concept Factorization With Adaptive Weights
Many traditional concept factorization methods employ single graph to approximate the manifold structure of data. Therefore, they cannot capture the underlying geometric structure hidden in data effectively.
