In this paper, a new low-complexity gradient-descent based iterative majority-logic decoder (GD-MLGD) is proposed for decoding One-Step Majority-Logic Decodable (OSMLD) codes. We give a formulation of the decoding problem of binary OSMLD codes, as a maximization problem of a derivable ...

使用TensorFlow打印自定义train_step函数中的值可以通过以下步骤实现: 首先,导入所需的TensorFlow库和其他必要的库: 代码语言:txt 复制 import tensorflow as tf 创建一个自定义的train_step函数,并在其中定义你想要打印的值。例如,假设你想要打印每个batch的损失值,可以这样定义train_step函数: 代码语言:txt 复制 @tf...
Watch step-by-step cartoon to visualize the calculation process of each method. Below is a demo of inner workings of momentum descent. Use visual elements to track things such as the gradient, the momentum, sum of squared gradient (visualized by squares whose sizes correspond to the magnitude ...
Should I just take the absolute value for the step size. Then, if for example I am using gradient descent, I can susbsitute the absolute value for the optimum step size in to eqn 1, xk+1=xk−α∇f(xk)xk+1=xk−α∇f(xk) pls help!!
0 how quickly will gradient descent converge given only a single training example for a regression problem? 3 for gradient descent, does there always a exist a step size such that the cost of the training error you are trying to minimize never increase? 1 how do i quan...

Stochastic gradient descent is the method of choice for large scale optimization of machine learning objective functions. Yet, its performance is greatly variable and heavily depends on the choice of the stepsizes. This has motivated a large body of research on adaptive stepsizes. However, there ...
