One of the early applications was pattern matching for LHC. I was in one of the groups in which some (not myself) worked on this and put the neural networks, using the just developed theory, in hardware with FPGA's. After a few years the three (post-docs) left and founded a startup. I lost contact with them. I think they were too early for broader applications, and had left the field completely in the early 2000's, when it really took of. Here is a book that the author of the referenced article , and the people from my group (Utrecht University), contributed to: https://link.springer.com/book/10.1007%2F978-1-4471-0877-1 https://link.springer.com/book/10.1007%2F978-1-4471-0877-1
