There are several use cases of RL algorithms.

Some of the most essential use cases are as follows:

• Text mining: Several researchers and companies have started to use the RL-based text generation model to produce highly readable text summaries from long text. 
• Robotics: Several deep RL-based algorithms are used in the field of robotics engineering to enhance the performance of robotics based on the reward system.
• Healthcare: Several studies show that RL can be used in healthcare to optimize medication dosage and treatment policies.
• Trading: Several RL-based models are used in trading businesses to optimize trading outcomes.
