In this work, we propose to address both the efficiency and ill-posedness of FWI by a geological constrained mini-batch gradient optimization method. The mini-batch gradient descent optimization is adopted to reduce the computation time by choosing a subset of entire shots for each iteration. By...
Predicting the Stagnation Time of Covid-19 Pandemic Using Bass Diffusion and Mini-Batch Gradient Descent Models The coronavirus (SARS-CoV-2), which first appeared in Wuhan, China, in December of 2019, spread quickly around the world, eventually categorizing it as a global "Epidemic". In early...

Mini Batch Gradient Descent is considered to be the cross-over between GD and SGD.In this approach instead of iterating through the entire dataset or one observation, we split the dataset into small subsets (batches) and compute the gradients for each batch. The formula of Mini Batch Gradient...
In the field of deep learning, where gradient-based local optimization methods are also in use28,29,30,31, model training often involves large datasets, requiring many independent model evaluations32,33. Mini-batch optimization addresses the issue of an increase in computation time as the number ...

The noisy learning process down the error gradient can also make it hard for the algorithm to settle on an error minimum for the model. What is Batch Gradient Descent? Batch gradient descent is a variation of the gradient descent algorithm that calculates the error for each example in the ...

This strategy reduces the error in gradient estimation compared to the conventional mini-batch stochastic gradient descent method. Our approach involves dividing the whole snapshot set into several Voronoi cells with low variance and extracting samples with good uniformity from each region to construct ...
To optimize the design of parallelized machine learning systems, the relationship between Stochastic Gradient Descent (SGD) learning time and node-level parallelism is explored. It has been found that a robust inverse relationship exists between minibatch size and the average number of SGD updates ...
