For major oxides one needs to recalculate the raw analysis data (K2O, Na2O, SiO2) for TAS diagram. What about trace elements? Do you need to recalculate them too for Winchester & Floyd (1977) diagram for compansating LOI values?
According to an author, it is best to recalculate all major oxides including TiO2. No need to recalculate trace elements.
I am studying the experimental application of reinforcement learning (RL) based control methods. For that reason, I modeled a nonlinear system without delay and trained the RL agent. In this...
