Shell Managing shell commands with Python Let's admit this, shell scripts sometimes can be hard to write. Especially if you got 1000s shell commands to run and would like to restrict the resources they can use on with a
Machine Learning Paper Reading Notes #03: meProp: Sparsified Back Propagation for Accelerated Deep Learning with Reduced Overfitting The paper "meProp: Sparsified Back Propagation for Accelerated Deep Learning with Reduced Overfitting" from ICML 2017 by researchers at Peking University. This paper presents a technique to speed up machine learning model training
Paper Paper Reading Notes #02: Towards Fully Sparse Training: Information Restoration with Spatial Similarity Computation graph from original paperPruning is a popular technique for reducing the size of deep neural networks without sacrificing accuracy. However, traditional pruning methods can be computationally expensive and lack to hardware support.
