The formula for calculating is: $${p}_{t}=\left\{ {\begin{array}{ll} {p} & \quad { if \;\; y=1} \\ {1-p} & \quad { otherwise } \\ \end{array} } \right.$$ (4) during the model training process, there is often a significant difference in the number of positive ...
The formulae are validated by comparison with previous work on the steady KdV equation. In particular, the mass flux, total head and momentum flux in the current context are compared to the quantities Q , R and S used in the work of Benjamin and Lighthill (Proc. R. Soc. Lon...
