示例1: createModel
static void createModel(ClassificationModel& model, const Parameters& parameters,
std::default_random_engine& engine)
{
NeuralNetwork featureSelector;
size_t totalPixels = parameters.xPixels * parameters.yPixels * parameters.colors;
// derive parameters from image dimensions
const size_t blockSize = std::min(parameters.xPixels, parameters.blockX) *
std::min(parameters.yPixels, parameters.blockY) * parameters.colors;
const size_t blocks = totalPixels / blockSize;
const size_t blockStep = blockSize / parameters.blockStep;
size_t reductionFactor = 4;
// convolutional layer
featureSelector.addLayer(Layer(blocks, blockSize, blockSize / reductionFactor, blockStep));
// pooling layer
featureSelector.addLayer(
Layer(1,
blocks * featureSelector.back().getOutputBlockingFactor(),
blocks * featureSelector.back().getOutputBlockingFactor()));
// contrast normalization
//featureSelector.addLayer(Layer(featureSelector.back().blocks(),
// featureSelector.back().getOutputBlockingFactor(),
// featureSelector.back().getOutputBlockingFactor()));
featureSelector.initializeRandomly(engine);
