TABLE 1.

The differences between our prior and our new progress indication methods.

Criterion	Our prior progress indication method	Our new progress indication method
Whether extra validation points are inserted between the original validation points (section III-B)	No	Yes
Whether at each validation point, the actual validation set used has the same count of data instances (section III-C)	Yes	No
Whether the relationship between the random noise’s variance and the size of the actual validation set used at the validation point is used (section III-D)	No	Yes
Whether maximum likelihood estimation is used to estimate the trend curve and the variance of the random noise (section III-E)	No	Yes
The minimum number of validation points required to employ the validation curve to re-estimate the count of original validation points required to train the model (section III-A)	3	4
