TL;DR: An overview of the BlueGene/L Supercomputer, a massively parallel system of 65,536 nodes based on a new architecture that exploits system-on-a-chip technology to deliver target peak processing power of 360 teraFLOPS (trillion floating-point operations per second).

Differential rewards with dynamic user profiling
TL;DR: In this paper, a methodology and system allows a plurality of reward scheme owners to give differential rewards to various users based on the user profile, and the reward distribution agent may be a seller, a manufacturer, a sales promotion agent or even an intermediary.

Gradient descent with sparsification: an iterative algorithm for sparse recovery with restricted isometry property
Rahul Garg,Rohit Khandekar +1 more
TL;DR: The Matlab implementation of GraDeS (Gradient Descent with Sparsification) outperforms previously proposed algorithms like Subspace Pursuit, StOMP, OMP, and Lasso by an order of magnitude and uncovered cases where L1-regularized regression (Lasso) fails but GraDeS finds the correct solution.
Patent
Generation, distribution, storage, redemption, validation and clearing of electronic coupons
TL;DR: In this article, a method and system generates, distributes, stores, redeems, validates and clears electronic manufacturer coupons and electronic store coupons and a coupon mint generates unforgable blank digital coupons.
Journal ArticleDOI
Prediction and interpretation of distributed neural activity with sparse models
TL;DR: This work applies a recently introduced regularized regression technique, the Elastic Net, to the analysis of the PBAIC 2007 competition data, and finds that this method produces highly predictive models of fMRI data that provide evidence for the distributed nature of neural function.
