Neural Networks with R

Cons

Let us take a look at some of the cons of neural networks:

• Neural networks are black boxes, meaning we cannot know how much each independent variable is influencing the dependent variables.
• It is computationally very expensive and time consuming to train with traditional CPUs.
• Neural networks depend a lot on training data. This leads to the problem of over-fitting and generalization. The mode relies more on the training data and may be tuned to the data.
