<span class="function"><a href="fann_get_cascade_activation_steepnesses.html" class="function">fann_get_cascade_activation_steepnesses()</a></span> 数组定义的。 这些数组定义的激活功能和激活的陡度用于候选神经元。如果在激活函数数组中有两个激活函数并且陡度数组中有三个陡度，则将会有2x3=6个不同的候选神经元被训练。 这6个不同的候选神经元将会被复制到几个候选组中，这些候选组不同之处在于他们的初始权重。如果组的数量设为2，则候选神经元的数量为2x3x2=12.候选组的数量是有 <span class="function"><a href="fann_set_cascade_num_candidate_groups.html" class="function">fann_set_cascade_num_candidate_groups()</a></span> 函数定义的。
