Gradient descent algorithmRegularizationInformation theoretic learning is a learning paradigm that uses concepts of entropies and divergences from information theory. A variety of signal processing and machine learning methods fall into this framework. Minimum error entropy principle is a typical one amongst...
In Section 3, we describe how a generic gradient descent algorithm operates, and also we list state-of-the-art algorithms to assign fixed priorities in real-time systems that conform with our model. Section 4 describes the main contribution of this paper, a Gradient Descent-based algorithm to...
On extremely ill-conditioned problems L-BFGS algorithm degenerates to the steepest descent method. Hence good preconditioner is needed to remedy this. Nonlinear CG retains its key properties independently of problem condition number (although convergence speed decreases on ill-conditioned problems). method...
Computer Science - Computer Science and Game TheoryGradient descent is an important class of iterative algorithms for minimizing convex functions. Classically, gradient descent has been a sequential and synchronous process. Distributed and asynchronous variants of gradient descent have been studied since ...

本文旨在给出Nesterov加速算法之所以能对常规一阶算法加速的一种algebraic解释,这种观点来自于将此种方法intepret成gradient descent(primal view)和mirror descent(dual view)的线性耦合(linear coupling)。这种观点是由 @Zeyuan AllenZhu 和Lorenzo Orecchia在14年严格提出(见下面文章链接)。 Allen-Zhu, Zeyuan, and ...
but can vary for different applications. Mini-batch gradient descent is typically the algorithm of choice when training a neural network and the term SGD usually is employed also when mini-batches are used. Note: In modifications of SGD in the rest of this post, we leave out the parametersx...
algorithm, rather than by the architecture alone, as evidenced by their ability to memorize pure noise19. Many potential implicit constraints have been proposed to explain why large neural networks work well on unseen data (i.e. generalize)20,21,22,23. One prominent theory is gradient descent ...
we don’t need to worry about complicated algebra and theory, noise, or signal characteristics – and the code is almost trivial. We obtain an optimal filter in a few thousand fast gradient descent iterations. Mean squared error (or any other metric, including very exotic ones, as long as ...
We propose a new stochastic gradient descent algorithm based on nested variance reduction. Compared with conventional stochastic variance reduced gradient (SVRG) algorithm that uses two reference points to construct a semi-stochastic gradient with diminishing variance in each epoch, our algorithm uses K+...
