The raw prediction result is 0.79, which is higher than 0.5, so the output is 1. The network made a correct prediction. Now try it with another input vector, np.array([2, 1.5]). The correct result for this input is 0. You’ll only need to change the input_vector variable since al...
Output: We can also use Seaborn library to create pairplots of all features in the dataset against each other. To use Seaborn, we need to import Seaborn library, first. Let’s see how it is done and how to create a Seaborn pairplot. Input: import seaborn as sns sns.set(style="ticks...
However, the R² calculated with test data is an unbiased measure of your model’s prediction performance. This is how it looks on a graph: The green dots represent the x-y pairs used for training. The black line, called the estimated regression line, is defined by the results of ...
