The Basic Ideas in Neural Networks (1994) [pdf]
I wonder why it is that articles written from way back when very often seem to have a way higher average quality than the stuff written today. I'm not sure the sole reason is that the only thing that survives is the high quality stuff, or because anyone can publish anything on the web, thus lowering the bar. It feels like even the peak of what we find today is rarely as good as the average found back then.
