Summary

In this chapter, you saw several ways to improve the performance of the RL method using a pure engineering approach, which was in contrast to the "algorithmic" or "theoretical" approach covered in Chapter 8, DQN Extensions. From my perspective, both approaches complement each other, and a good RL practitioner needs to both know the latest tricks that researchers have found and be aware of the implementation details.

In the next chapter, we will apply our DQN knowledge to stocks trading.
