Dataset-6. Validation and test subsets have a uniform
density over the input range. The noise magnitude
( )Me
is 0.5.
In Dataset-7, the sample density increases with the
increment of the absolute value of X1. Figure 5(b) presents
the training set of Dataset-7. Validation and test subsets
have a uniform density over the input range. The noise
magnitude
( )Me
is 0.5.
The artificial NN may confuse the noise with a high-frequency
signal, where human brains can easily recognize
the pattern of the signal. The equation for the generation of
Dataset-8 is the same as (7). The noise magnitude ( )Me
in
Dataset-8 is 0.2. However, the input range of Dataset-8 is
larger than Dataset-6. Figure 5(c) indicates the training set
of Dataset-8. All subsets of Dataset-8 have a uniform density
over the input range.
The noise magnitude
( )Me
in Dataset-9 is 0.2. Figure
6(a)-(c) presents the training, validation, and test
sets of Dataset-9. The training set has no sample near
X .10=
The noise magnitude
( )Me
in Dataset-10 is 0.2. Figure 7(a)
