XOR problem
build: 2016-07-16 solved: No
- XOR problem:
[input, output1]
pairs--[(1, 0), 1], [(0, 1), 1], [(0, 0), 0], [(1, 1), 0]
- a two-layers network can approximate this XOR function, with 2 input layer nodes and 1 output node (sigmoid activation)
NAND problem
build: 2016-07-16 solved: No
- NAND problem:
[input,, output]
pairs--[(1, 0), 1], [(0, 1), 1], [(0, 0), 1], [(1, 1), 0]
- may be a two-layers network can approximate this NAND function, with 2 input layer nodes and 1 output node (sigmoid activation)
