Impurity calculation
WitrynaThe Gini Impurity is a downward concave function of p_{c_n}, that has a minimum of 0 and a maximum that depends on the number of unique classes in the dataset.For the 2-class case, the maximum is 0.5. For the multi-class case the maximum G_{max} will be 1.0 > G_{max} > 0.5, where more classes will yield a larger maximum.An example of … WitrynaThese impurity elements were arranged at the body center sites of the two unit cells to simplify the calculation. When doped with Nb 5+ and In 3+, the mapping color indicating the electron charge density in the diffusion path changes to light blue but remained deep blue for Ta 5+ doping. Figure 10b summarizes the calculation results of the ...

WitrynaSo the equation to calculate the impurity percentage is impurity percentage equals the mass of the impurities divided by the mass of the sample times 100 percent. The mass of the impurities is 35 grams. The total mass of the river water sample is 140 grams. Performing the calculation, we find that the impurity percentage is 25 percent.
