How do you calculate misclassification rate? Misclassification Rate: It tells you what fraction of predictions were incorrect. It is also known as Classification Error. You can calculate it using (FP+FN)/(TP+TN+FP+FN) or (1-Accuracy). Precision: It tells you what fraction of predictions as a positive class were actually positive. How is F1 Micro calculated? To calculate the micro-F1, we first compute micro-averaged precision and micro-averaged recall over all the samples , and then combine the two. How do we “micro-average”? We simply look at all the samples together. Remember that precision is the proportion of True Positives out of the Predicted Positives...

What is BRONZclay? What Is BRONZclay? The material is a mixture of microscopic metal particles (11% tin and 89% copper) held together with an organic binder and water. Most of the water evaporates as the clay dries. The binder and remaining water burn away or evaporate during firing, and what remains is pure bronze metal. Can bronze Clay be fired with a torch? Firing bronze metal clay can be done in a kiln or with a hand torch. But remember that pieces of bronze metal clay that are larger than a 50 pence piece are much easier to fire in...
