Gradient Descent Meets Shift-and-Invert Preconditioning for Eigenvector Computation

Neural Information Processing Systems

Shift-and-invert preconditioning, as a classic acceleration technique for the leading eigenvector computation, has received much attention again recently, owing to fast least-squares solvers for efficiently approximating matrix inversions in power iterations.



Revisiting Multi-Task Learning with ROCK: a Deep Residual Auxiliary Block for Visual Detection

Neural Information Processing Systems

Extensiveexperiments on NYUv2 dataset (object detection with scene classification, depth prediction, and surface normal estimation as auxiliary tasks) validate the relevance of the approach and its superiority to flat MTL approaches.
