# using the Forward-Forward algorithm to train a neural network to classify positive and negative data 
# the positive data is real data and the negative data is generated by the network itself 
# the network is trained to have high goodness for positive data and low goodness for negative data 
# the goodness is measured by the sum of the squared activities in a layer 
# the network is trained to correctly classify input vectors as positive data or negative data 
# the probability that an input vector is positive is given by applying the logistic function, σ to the goodness, minus some threshold, θ 
# the negative data may be predicted by the neural net using top-down connections, or it may be supplied externally

/////////////////////// Put x87 FPU in double-precision mode //////////////////

// For cross-platform portability, force x87 floating-point calculations to be
// done with intermediate results stored in double precision (53 bit mantissa)
// instead of extended double precision (64 bit mantissa) registers.  We change
// the x87 control register to accomplish this.  But it only affects the
// mantissa, not the exponent, so does not remove all inconsistencies.
