Most neural networks begin by computing the weighted sum of the inputs. Each node in the layer can have its own unique weighting. However, the activation function is the same across all nodes in the layer.PCA creates the first principal component, PC1, and the second principal component, PC2 is 90 degrees to the first component. Both these components absorb all the covariances present in the mathematical space. We can then drop the original dimensions X 1 and X 2 and build our model using only these principal components PC1 and PC2.
