. var endTime = new Date (theTime) to create the current time object.4. var totalSecs = (endTime-new Date ()/1000. The difference between the two time objects is the millisecond gap between the two objects. Dividing by 1000 is the difference description.5. var days = Math. floor (totalSecs/3600/24), calculate the number of days of the difference, pay special attention to the role of the Math. floor () function. For more information, see.6. var hours = Math. floor (totalSecs-days * 24*3600)/3600)

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
