Adadb: Adaptive Diff-Batch Optimization Technique for Gradient Descent
نویسندگان
چکیده
Gradient descent is the workhorse of deep neural networks. has disadvantage slow convergence. The famous way to overcome convergence use momentum. Momentum effectively increases learning factor gradient descent. Recently, many approaches have been proposed control momentum for better optimization towards global minima, such as Adam, diffGrad, and AdaBelief. Adam decreases by dividing it with square root moving averages squared past gradients or second moment. sudden decrease in moment often results overshoot from minima then settle at closest minima. DiffGrad this problem using a friction constant based on difference current immediate Adam. further AdaBelief adapts step size according belief direction. Another fast increase batch adaptively. This paper proposes new technique named adaptive diff-batch adadb that removes overshooting combines methods rate. uses three differences rather than one diffGrad condition decide constant. outperformed optimizers synthetic complex non-convex functions real-world datasets.

Adaptive Online Gradient Descent
We study the rates of growth of the regret in online convex optimization. First, we show that a simple extension of the algorithm of Hazan et al eliminates the need for a priori knowledge of the lower bound on the second derivatives of the observed functions. We then provide an algorithm, Adaptive Online Gradient Descent, which interpolates between the results of Zinkevich for linear functions ...

متن کاملDistributed Stochastic Optimization via Adaptive Stochastic Gradient Descent
Stochastic convex optimization algorithms are the most popular way to train machine learning models on large-scale data. Scaling up the training process of these models is crucial in many applications, but the most popular algorithm, Stochastic Gradient Descent (SGD), is a serial algorithm that is surprisingly hard to parallelize. In this paper, we propose an efficient distributed stochastic op...
متن کاملMutiple-gradient Descent Algorithm for Multiobjective Optimization
The steepest-descent method is a well-known and effective single-objective descent algorithm when the gradient of the objective function is known. Here, we propose a particular generalization of this method to multi-objective optimization by considering the concurrent minimization of n smooth criteria {J i } (i = 1,. .. , n). The novel algorithm is based on the following observation: consider a...
متن کاملAdaptive Variance Reducing for Stochastic Gradient Descent
Variance Reducing (VR) stochastic methods are fast-converging alternatives to the classical Stochastic Gradient Descent (SGD) for solving large-scale regularized finite sum problems, especially when a highly accurate solution is required. One critical step in VR is the function sampling. State-of-the-art VR algorithms such as SVRG and SAGA, employ either Uniform Probability (UP) or Importance P...
