Before Change

	def transform(self, X):
		 iterate through the input columns, binarizing each 
		self.cols_list = list(self.X.columns)
		encoder = LabelBinarizer()	
		self.binarized_cols = encoder.fit_transform(self.X[self.cols_list.pop(0)])
		self.classes_ = list(encoder.classes_)
		for i in self.cols_list:
			encoder = LabelBinarizer()
			binarized_col = encoder.fit_transform(self.X[i])

After Change

		self.X = X
		self.binarized_cols = self.binarizers[0].transform(self.X[self.cols_list[0]])
		self.classes_ = list(self.binarizers[0].classes_)
		for i in range(1,len(self.cols_list)):
			binarized_col = self.binarizers[i].transform(self.X[self.cols_list[i]])
			self.binarized_cols = np.concatenate((self.binarized_cols , binarized_col), axis = 1)
			self.classes_.extend(list(self.binarizers[i].classes_))
