increase in the sample capacity m of the training set, because the more data you use, the more you will be able to achieve better generalization performance, or the ability to adapt to new samples is stronger. As a result, the more data you have, the more appropriate assumptions can be fitted. So, if you draw Jtrain and JCV, you should get the following curves.Now let's see what these learning curves will look like when they are in high or
