EIE: Efficient Inference Engine on Compressed Deep Neural Network
TLDR
An energy efficient inference engine (EIE) that performs inference on this compressed network model and accelerates the resulting sparse matrix-vector multiplication with weight sharing and is 189x and 13x faster when compared to CPU and GPU implementations of the same DNN without compression.

Exploring the Regularity of Sparse Structure in Convolutional Neural Networks
TLDR
This paper quantitatively measure the trade-off between sparsity regularity and prediction accuracy, providing insights in how to maintain accuracy while having more a more structured sparsity pattern. Expand
Efficient Sparse-Winograd Convolutional Neural Networks
TLDR
Two modifications to Winograd-based CNNs are proposed to enable these methods to exploit sparsity, including moving the ReLU operation into the Winog Rad domain to increase the sparsity of the transformed activations and prune the weights in the Winogsrad domain to exploit static weight sparsity.

Exploring the Granularity of Sparsity in Convolutional Neural Networks
TLDR
This analysis, based on the framework of a recent sparse convolutional neural network (SCNN) accelerator, demonstrates that coarse-grained sparsity saves 30% – 35% of memory references compared with fine-graining sparsity. Expand
A Statistical Test of Phase Closure to Detect Influences on DInSAR Deformation Estimates Besides Displacements and Decorrelation Noise: Two Case Studies in High-Latitude Regions
TLDR
An asymptotic Wald significance test is proposed, which detects situations when the observed closure error cannot solely be explained by noise, and indicates the presence of processes that can have systematic and deleterious impacts on the estimation of surface movements. Expand
Pruning of Winograd and FFT Based Convolution Algorithm
Winogradand FFT-based convolution are two efficient convolution algorithms targeting high-performance inference. Their efficiency comes from the reduction of the number of multiplication operations… Expand
