+## 简介
+
+[《FiBiNET: Combining Feature Importance and Bilinear feature Interaction for Click-Through Rate Prediction》]( https://arxiv.org/pdf/1905.09433.pdf)是新浪微博机器学习团队发表在RecSys19上的一篇论文，文章指出当前的许多通过特征组合进行CTR预估的工作主要使用特征向量的内积或哈达玛积来计算交叉特征，这种方法忽略了特征本身的重要程度。提出通过使用Squeeze-Excitation network (SENET) 结构动态学习特征的重要性以及使用一个双线性函数来更好的建模交叉特征。
+
+本项目在paddlepaddle上实现FibiNET的网络结构，并在开源数据集Criteo上验证模型效果。
+
+## 数据下载及预处理
+
+数据地址：[Criteo]( https://fleet.bj.bcebos.com/ctr_data.tar.gz)
+
+（1）将原始训练集按9:1划分为训练集和验证集
+
+（2）数值特征（连续特征）进行归一化处理
+
+执行run.sh生成训练集和测试集
+
+```
+sh run.sh
+```
+
+## 环境
+
+PaddlePaddle 1.7.2
+
+python3.7 
+
+PaddleRec
+
+## 单机训练
+
+CPU环境
+
+在config.yaml文件中设置好设备，epochs等。
+
+```

 使用样例数据快速开始，参考[训练](###训练) & [预测](###预测)
 ## 使用教程(复现论文)
 为了方便使用者能够快速的跑通每一个模型，我们在每个模型下都提供了样例数据，并且调整了batch_size等超参以便在样例数据上更加友好的显示训练&测试日志。如果需要复现readme中的效果请按照如下表格调整batch_size等超参，并使用提供的脚本下载对应数据集以及数据预处理。
