As explained above, the impact of different ZWD models is more pronounced for the fixed solu- tion. While the differences are generally small, there is again a fairly consistent ranking, with ZWDX per- forming best and VMF1 performing worst. Interesting cases with relevant differences include ...
The codes are very well explained. I don’t see this book as merely a how-to tutorial, it’s a very noble cause by disseminating your knowledge and skill to empower others to excel in Machine Learning. Jong Hang Siong Consultant at Teradata ...

MSE measures the average squared difference between predicted and actual values, MAE calculates the average absolute difference, and R² indicates the proportion of variance in the target variable explained by the model. MAE and coefficient of determination (R2) are provided below:(12)MAE=1n∑i=...
This tendency to underestimate wave height and wind speed can be explained by the limited number of extreme wave heights and wind speeds available for model training. Comparable results were found by Hu, Haoguo, et al. for predicting wave height during storm events24. The models tended to ...
