C++ :: Cannot Seem To Find Logic Error In Perceptron

I can't seem to find the logic error in my perceptron. The perceptron's feedback function pushes back a bias of 1.0 into the input vector, and calculates the dot product of the input vector and it's weight vector, and returns 1 if the dot product is > 0, and -1 otherwise. This will determine whether the inputted point is above or below the hyperplane given by the functor.

The training function instantiates a trainer object , which feeds it a vector random numbers, along with the correct answer (in this case, whether the point is above or below the hyperplane given by a functor). It then calls the feedback function, and subtracts its answer from the correct answer, and updates the weights by adding the input vector to the weight vector, and multiplying the weight vector by the error, and by a correction factor, in this case 0.01.
