Review of Large-Scale Simulation Optimization
arXiv · Optimization and Control(2024)
Abstract
Large-scale simulation optimization (SO) problems encompass both large-scale
ranking-and-selection problems and high-dimensional discrete or continuous SO
problems, presenting significant challenges to existing SO theories and
algorithms. This paper begins by providing illustrative examples that highlight
the differences between large-scale SO problems and those of a more moderate
scale. Subsequently, it reviews several widely employed techniques for
addressing large-scale SO problems, such as divide and conquer, dimension
reduction, and gradient-based algorithms. Additionally, the paper examines
parallelization techniques leveraging widely accessible parallel computing
environments to facilitate the resolution of large-scale SO problems.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
