If the execution is not done properly while using gradient descent, it may lead to problems like vanishing gradient or exploding gradient problems. These problems occur when the gradient is too small or too large. And because of this problem the algorithms do not converge. 2.3 Implementation Chal...
In this paper, we provide an overview of first-order and second-order variants of the gradient descent method that are commonly used in machine learning. We propose a general framework in which 6 of these variants can be interpreted as different instances of the same approach. They are the ...

Now let’s discuss the three variants of gradient descent algorithm. The main difference between them is the amount of data we use when computing the gradients for each learning step. The trade-off between them is the accuracy of the gradient versus the time complexity to perform each parameter...
The Frontier of SGD and Its Variants in Machine Learning Stochastic gradient descent(SGD) is pretty simple but surprisingly, highly effective in machine learning models, such as support vector machine(SVM) and deep neural network(DNN). Theoretically, the performance of SGD for convex optimization.....

In this study, we propose a regularized deep learning model to select causal regions for the target disease. With the help of the proximal [20] gradient descent algorithm, the model utilizes the group LASSO concept and embraces a deep learning model in a sparsity framework. We perform the CNV...
Associations between common genetic variants and income provide insights about the socio-economic health gradient Abstract We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and ...
