Prepare the Data to Create a Correlation Matrix in R The correlation coefficient can only be computed for numeric data. The data must not just look like numbers; it must be in numeric format. There are two-factor columns in the following sample data frame comprised of numbers and a character...
Now it’s time to create the train() method of your NeuralNetwork class. You’ll save the error over all data points every 100 iterations because you want to plot a chart showing how this metric changes as the number of iterations increases. This is the final train() method of your neu...
