KNIME Deep Learning - Keras Integration version 3.6.0.v201807091039 by KNIME AG, Zurich, Switzerland
Exponential linear units were introduced to alleviate the disadvantages of
ReLU and LeakyReLU units, namely to push the mean activation closer to zero while
still saturating to a negative value which increases robustness against noise if the unit is
in an off state (i.e. the input is very negative).
The formula is
f(x) = alpha * (exp(x) - 1) for x < 0 and f(x) = x for x >= 0.
For the exact details see the corresponding paper.
Corresponds to the
Keras ELU Layer.
