-depth learning model Framework:In the offline phase, we use the theano, tensorflow-based Keras as the model ENGINE. At the time of training, we separately cleaned and weighted the sample Data. In terms of features, we use the Min-max method for normalization of continuous features. In terms of cross-features, we combine business requirements to refine multiple cross-features that are more significant in business Scenarios. In the model we use Adam as

of the lake water is very deep, say many lost. If you say the wrong thing, the other door may be unhappy.I like TensorFlow better. But TensorFlow itself is a bottom-level library. Although the interface becomes more and more easy to use as the version changes. But for beginners, many details are still too trivial and difficult to master.Beginner's patience is limited, frustration is too easy to give up.Fortunately, there are several highly abstract frameworks that are built on top of TensorFlow

on Adam basis) There are so many optimization algorithms, so how do we choose it. The great God has given us some advice [2][3] If you have a small amount of data input, choose an adaptive learning rate method. This way you don't have to tune the learning rate, because your data is small, and NN learning is a little time-consuming. In this case you should be more concerned about the accuracy of network classification. Rmsprop, Adadelta, are very similar to Adam and perform well in the same situ

introduction to depth learning, the best I've encountered is Deep Learning with Python. It doesn't go deep into difficult math, nor does it have a long list of prerequisites, but describes a simple way to start a DL, explaining how to quickly start building and learn everything in practice. It explains the most advanced tools (Keras,tensorflow) and takes you through several practical projects to explain how to achieve the most advanced results in all
