Can anyone help me understand the difference between two plots ?
and what does this line mean
ax2.plot(100 + np.arange(len(J_hist[100:])), J_hist[100:])
The plot on the right is a zoomed-in region of the lower-right quadrant of the left plot.
It shows that the cost is still decreasing over the last few hundred iterations.
That code generates indices for the range of cost values starting from index100 and continuing to the end of the data.
