An important note: since Python 2 has become outdated, it is no longer available on Colab. However, there is still legacy code running Python 2. Thankfully, Colab has afix for this, which you can use to still run Python 2. If you give it a try, you’ll see there’s a warning th...

Neural Networks and Deep Learning(week4)Building your Deep Neural Network: Step by Step,程序员大本营,技术文章内容聚合第一站。
We'll be building a deep Q-network implementation in the next chapter. Many people use the term "deep learning" in association with any machine learning model that uses neural networks, and, in fact, some incorrectly generalize the term "deep Q-network" to include any Q-learning ...
