Farag, Mark – Mathematics and Computer Education, 2007
Hill ciphers are linear codes that use as input a "plaintext" vector [p-right arrow above] of size n, which is encrypted with an invertible n x n matrix E to produce a "ciphertext" vector [c-right arrow above] = E [middle dot] [p-right arrow above]. Informally, a near-field is a triple [left angle bracket]N; +, *[right angle bracket] that…

Bowers, Jeffrey S. – Cognitive Psychology, 2002
One of the central claims associated with the parallel distributed processing approach popularized by D. E. Rumelhart, J. L. McClelland and the PDP Research Group is that knowledge is coded in a distributed fashion. Localist representations within this perspective are widely rejected. It is important to note, however, that connectionist networks…
