In this step-by-step tutorial, you'll build a neural network from scratch as an introduction to the world of artificial intelligence (AI) in Python. You'll learn how to train your neural network and make accurate predictions based on a given dataset.
We simply use matplotlib to display a scatter plot of cost_history. It allows us to visualize cost by iteration, in the first iterations, the cost is high, while at the end, the cost tends to be 0. plt.plot(range(num_iterations),cost_history,marker='o')plt.xlabel('Iteration')plt.yl...
