WebI am using python 2.7.1 I want to encrypt sth using AES in CTR mode. I installed PyCrypto library for python. I wrote the following code: secret = os.urandom (16) crypto = AES.new (os.urandom (32), AES.MODE_CTR, counter=lambda: secret) encrypted = crypto.encrypt ("asdk") print crypto.decrypt (encrypted) Web目标：CTR预估. 以前的CTR预估模型仅考虑low-order的特征交互或者仅考虑high-order的特征交互，需要手工设计特征。文中提出了DeepFM来同时学习low-order和high-order的特征交互，不需要手工设计特征。 CTR数据特点：（重点在于学习低阶与高阶的组合特征）
