Deepctr

Change Log
Major Features and Improvements

- Refactor inputs module,now you can input different features to linear part and dnn part of the models.
- Dense value inputs are concated with the inputs of dnn instead of embed into dense vectors.
- **previous versions of the code require modification to work properly**,please refer [new examples](https://deepctr-doc.readthedocs.io/en/latest/Examples.html) to update your codes.

Change Log
Major Features and Improvements
- **Previous versions of the code require a little modification to work properly**
- Support feature hashing on the fly in training and inference process [example](https://deepctr-doc.readthedocs.io/en/latest/Examples.html#classification-criteo-with-feature-hashing-on-the-fly)
- Add python2.7 support
- Refactor methods in `input_embedding.py`
- Refactor layers and models

API changes
- `deepctr.utils.SingleFeat`and `deepctr.utisl.VarlenFeat` add new arguments to support feature hashing
- `deepctr.core.MLP` to `deepctr.core.DNN`
- arguments of all models and layers changes

- Add [FGCNN(Feature Generation by Convolutional Neural Network)](https://deepctr-doc.readthedocs.io/en/latest/Features.html#fgcnn-feature-generation-by-convolutional-neural-network)[CCPM&FGCNN:使用CNN进行特征生成的CTR预测模型](https://zhuanlan.zhihu.com/p/64015347)
- Add `FGCNNLayer` in `deepctr.layers.interaction` [doc](https://deepctr-doc.readthedocs.io/en/latest/deepctr.layers.interaction.html#deepctr.layers.interaction.FGCNNLayer)
- Now we can use deepctr under `tensorflow 1.13`, but there may be some compatibility issues.
