the opening paragraph introduction could be re worded to sound a little nicer i feel as though the introduction sets the stage for the entire article so it is worth putting in the extra effort to make it flow however the hyperlinks inserted into the first paragraph are good the outline of the bibliography is really good however in the first paragraph the sentence afterwards he became a faculty member at the university of california san diego for years sounds awkward and could be re worded the spacing between your referencing end notes and the start of a new sentence is not consistent make sure there is a space between the endnote and the start of the next sentence it might be beneficial to add a figure into your article in regards to the interactive activation model could also potentially add one to illustrate backpropagation the first sentence in the back propagation learning algorithm paragraph could flow a little better could also potentially add a chart in at the end of your article so summarize rumelhart s research theories i feel as though this would really benefit your article because you mention so many theories overall good article with a lot of good information also written in a way that would be easy for the general public to understand andrew nicholson
