Abstract
The echo state network (ESN) has a special hidden layer called the reservoir. Compared with the traditional recurrent neural network (RNN), the ESN has a higher training efficiency, solving the problems of vanishing or exploding gradients. However, there are many parameters in ESN, which can affect the prediction effect. The Dung Beetle Optimization (DBO) algorithm shows great advantages in optimization problems and has a good ability to jump out of the local optimum. In this paper, the DBO is used to optimize the parameters of ESN. Optimizing parameters include reservoir neurons, spectral radius, input scale, and sparsity. The DBO-ESN is applied to the classification of breast cancer, and compares with the ESN based on particle swarm optimization (PSO-ESN), the ESN based on whale optimization algorithm (WOA-ESN), and ESN. The results show that the DBO-ESN has the best classification accuracy.

- 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
