Open the CIPO recordAbstract From the Canadian patent
A numeric encoding method and apparatus for neural networks, encodes numeric input data into a form applicable to an input of a neural network by partitioning a binary input into N-bit input segments each of which is, replaced with a code having M adjacent logic ones and 2N-1 logic zeros, the bit position of the least significant of the M logic ones corresponding to the binary value of the input segment it replaces. The codes are concatenated to form an encoded input. A decoding method decodes an output from the neural network into a binary form by partitioning the output into output segments having 2N+M-1 bits each, each of which is replaced with an N-bit binary segment being a bracketed …

Why it's free to use
- Filed April 30, 1990 and granted September 7, 1993. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 30, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 30, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
