Prediction of open-pit mine truck travel time based on LSTM-TabTransformer
Scientific ReportsTruck travel time prediction is the basis for real-time optimal scheduling decision of open-pit trucks. Most prediction models for open-pit truck travel time mainly rely on a single machine learning algorithm or model to optimize the hyperparameters ...
