Accurate electricity price forecasting is of great importance to all participants in the market, which can provide powerful support for them to make wise decisions in the unpredictable market. In this paper, we propose to use the MLP-Mixer model as a new technique for electricity price forecasting. This model considers the various factors affecting electricity price fluctuations and can use the MLP-Mixer model for concise and practical feature extraction and information interaction, ultimately achieving more accurate electricity price forecasting. The effectiveness of the proposed model is verified by using data from ERCOT, Texas electricity market. Empirical results show that the proposed model can significantly improve the forecasting accuracy, and achieves the optimal results on four evaluation metrics, which fully demonstrates the model's effectiveness for electricity price forecasting.
Volcanic rock formations, as an important oil and gas resource reservoir, have received the focus of the energy industry in recent years. Shear wave logging is essential geophysical data for the exploration and evaluation of volcanic rock oil and gas reservoirs. Due to the strong nonlinear relationship between reservoir logging parameters and S-wave velocity, the conventional point-to-point machine learning methods can not effectively construct the feature space. Deep learning adds neighborhood information to learn the depth features relationship, and builds the mapping of S-wave velocity and wireline logs with its powerful nonlinear solving capability, achieves S-wave velocity prediction. Taking the volcanic reservoir in Xujiaweizi area of Songliao Basin in Northeast China as an example, thirteen logging parameters sensitive to S-wave velocity are selected, and the S-wave velocity prediction models are based on deep learning methods (represented by CNN, ViT, and MLP-Mixer) are proposed. The research demonstrates that the proposed deep learning models are able to predict S-wave velocity with more precision, and the modeling method can give great significance for the exploration of the volcanic reservoir.
