See someone using TensorFlow to reproduce the yoloV3, to record the code reading. The code that feels reproduced is not written very well, and some other people use Keras to reproduce the code.TensorFlow Code Address: 79940118The source code is divided into the following sections:train.py The main program train.py part of the training of their own data set, eval.py to take advantage of the training of good weights to predict.

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

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

In many machine learning and depth learning applications, we find that the most used optimizer is Adam, why?
The following is the optimizer in TensorFlow:

I began three years ago to learn deep learning, these deep learning frameworks are also a change, from Keras, Theano, Caffe, Darknet, TensorFlow, and finally now to start using Pytorch.

Google is not only the leader in big data and cloud computing, but also has a good practice and accumulation in machine learning and deep learning, and at the end of 2015, open Source was used internally by the deep learning framework TensorFlow. Compared with Caffe, Theano, Torch, mxnet and other frameworks, TensorFlow has the largest number of fork and star numbers
