The role which a FPGA-based platform plays in neural network implementation, and what part(s) of the algorithm it's responsible for carrying out, can be classified into two styles of architecture, as either a co-processor or as a stand-alone architecture. The XOR problem that a single layer network cannot solve. The XOR problem requires that the neuron respond (i.e., white circles) when only one (but not both) of the inputs is on. This is not solvable by a single-layer perceptron or linear network because it is not linearly separable. The revived interest in neural networks occurred in part with the advent of multilayer, nonlinear networks with

Is there any free paper about the 3 hidden-layer XOR network (2 hidden-layer ffnn converges to this too), and if it has a local minima (at 0.35), or it is just my implementation problem?

Radial-Basis Function Networks 7 take a different approach by viewing the design of a neural network as a cumelfitting (approximation) problem in a high-dimensional space. According to this viewpoint, learn- ing is equivalent to finding a surface in a multidimensional space that provides a best fit to the training data, with the criterion for “best fit” being measured in some popularity in neural networks is because the sigmoid function satisfies a property between the derivative and itself such that it is computationally easy to perform.
