首先,我使用 myModel.fit() 来训练模型,并在该过程中定义了 validation_data,在训练的每个epoch后验证模型,假设这个验证模型的数据集为 eval_data(也即validation_data = eval_data),通过训练日志,我可以看到最好的模型在验证集上的acc是 91.37% 其次在训练好模型后,我通过 load_model 加载最优模型,记为 best...

Comparing models built upon remotely-sensed datasets with those built upon a data-assimilative configuration of the Regional Ocean Modelling System (ROMS), we explore trade-offs in model construction and address how physical data can affect predictive performance and operational capacity.
