示例1: __init__
# 需要导入模块: from rbm import RBM [as 别名]
# 或者: from rbm.RBM import regenerate [as 别名]
class SFG:
def __init__(self):
self.image_width = self.image_height = 28
self.visible_units = self.image_width * self.image_height
self.hidden_units = self.visible_units / 10
self.rbm = RBM(self.visible_units, self.hidden_units)
#assumes there are only training images in the training_folder
def train(self, training_folder, epochs = 500):
data = []
for training_image in os.listdir(training_folder):
image = pil.open(training_folder + '/' + training_image)
image = self.array_for_image(image)
data.append(image)
self.rbm.train(data, epochs)
#takes a pil Image and returns an arary of 1s and 0s
def array_for_image(self, image):
return np.array(image.convert("L")).flatten() / 255
def regen_image(self, image, samples):

return pil.fromarray(img_array)示例2: RBMTest
