Engineers (IEEE) Computational Intelligence Society (CIS) Neural Networks Pioneer Award and the 2018 National Federation of Advanced Information Services (NFAIS) Miles Conrad Award. He has twice received the IBM Distinguished Faculty Award. Electromagnetics Before his work on neural networks, Giles published papers on reflection and scattering of electromagnetic waves from magnetic materials for the particular cases of equal refractive indexes. His work is mentioned in the following articles: Fresnel equations, Mie scattering, and Brewster's angle. For Mie scattering, he is a coauthor on the Kerker effect, which was an extension of his work on a planar boundary effect and his idea. Neural networks Giles' work on neural networks showed that fundamental computational structures such as regular grammars and finite state machines could be theoretically represented in recurrent neural networks. Another contribution was the Neural Network Pushdown Automata and the first analog differentiable stack. Some of these publications are cited as early work in "deep" learning. CiteSeer and search engines In 1998 and 1999 his work published in Science and Nature with Steve Lawrence estimated the size of the web and showed that search engines did not index that much of it. This work also showed that the web had significantly matured and had a diversity of material and resources. With Steve Lawrence and Kurt Bollacker, Giles was responsible for the creation in 1997 of automatic citation indexing and CiteSeer, a public academic search engine and digital library for Computer and Information Science. Under his direction CiteSeer was moved to and is being maintained at the Pennsylvania State University. CiteSeer has been replaced by the Next Generation CiteSeer, CiteSeerX. He is the director of the Next Generation CiteSeer project, CiteSeerX, also at the Pennsylvania State University. In addition, he was responsible for the creation of an academic business search engine and digital library, BizSeer (previously known as SmealSearch). With Isaac Councill, he created automatic acknowledgement indexing, permitting for the first time the automatic search and indexing of acknowledged entities in scholarly and research documents. The search engine for this was AckSeer. He also was the cocreator of the first search engine for robots.txt, BotSeer. Research in collaboration with Professors Prasenjit Mitra, Karl Mueller, Barbara Garrison and James Kubicki resulted in the development of a search engine and data portal for chemistry, ChemxSeer, ChemXSeer. With Yang Sun, a novel search engine, BotSeer, was designed that searches and indexes robots.txt files on web
