Implicit Stochastic Gradient Descent Method for Cross-Domain Recommendation System [PDF]

open access: yesSensors, 2020
The previous recommendation system applied the matrix factorization collaborative filtering (MFCF) technique to only single domains. Due to data sparsity, this approach has a limitation in overcoming the cold-start problem.

Stochastic Modified Flows for Riemannian Stochastic Gradient Descent

open access: yesSIAM Journal on Control and Optimization
Abstract. We give quantitative estimates for the rate of convergence of Riemannian stochastic gradient descent (RSGD) to Riemannian gradient flow and to a diffusion process, the so-called Riemannian stochastic modified flow (RSMF). Using tools from stochastic differential geometry, we show that, in the small learning rate regime, RSGD

Dual Stochastic Natural Gradient Descent

open access: yesCoRR, 2020
[EN] Although theoretically appealing, Stochastic Natural Gradient Descent (SNGD) is computationally expensive, it has been shown to be highly sensitive to the learning rate, and it is not guaranteed to be convergent. Convergent Stochastic Natural Gradient Descent (CSNGD) aims at solving the last two problems.

Stochastic gradient descent for wind farm optimization [PDF]

open access: yesWind Energy Science, 2023
It is important to optimize wind turbine positions to mitigate potential wake losses. To perform this optimization, atmospheric conditions, such as the inflow speed and direction, are assigned probability distributions according to measured data, which ...

AG-SGD: Angle-Based Stochastic Gradient Descent

open access: yesIEEE Access, 2021
In the field of neural network, stochastic gradient descent is often employed as an effective method of accelerating the result's convergence. Generating the new gradient from the past gradient is a common method adopted by many existing optimization ...

Stochastic Reweighted Gradient Descent

open access: yesCoRR, 2021
Despite the strong theoretical guarantees that variance-reduced finite-sum optimization algorithms enjoy, their applicability remains limited to cases where the memory overhead they introduce (SAG/SAGA), or the periodic full gradient computation they require (SVRG/SARAH) are manageable.

Almost sure convergence of randomised‐difference descent algorithm for stochastic convex optimisation

open access: yesIET Control Theory & Applications, 2021

Stochastic gradient descent on GPUs [PDF]

open access: yesProceedings of the 8th Workshop on General Purpose Processing using GPUs, 2015
Irregular algorithms such as Stochastic Gradient Descent (SGD) can benefit from the massive parallelism available on GPUs. However, unlike in data-parallel algorithms, synchronization patterns in SGD are quite complex. Furthermore, scheduling for scale-free graphs is challenging.
