Introduction to Deep Reinforcement Learning in AI

Deep learning, an intriguing aspect of artificial intelligence (AI), has contributed to remarkable achievements in the AI sector, such as autonomous vehicles, AI-designed hardware, and robots. Deep reinforcement learning, a more complex aspect of deep learning, employs the learning capabilities of deep neural networks to tackle issues that conventional reinforcement learning (RL) methods cannot solve.

Understanding Reinforcement Learning Dynamics

In any reinforcement learning scenario, an agent and an environment are the core elements. The environment provides information about the current system status, and the agent interacts with the environment by observing these states and executing actions, which can either be continuous or discrete. As these actions take place, the environment changes, and based on the new state's relevancy to the system's goal, the agent receives a reward. This learning process cycles through stages until the target state or maximum allowed steps are achieved.

Goal of Reinforcement Learning

The intention of reinforcement learning is to train the agent to make choices that yield maximum rewards. The decision-making function of the agent is called a policy. The objective of deep inverse reinforcement learning, which could take several episodes depending on the complexity of the problem, is to infer the inherent reward structure guiding the agent's behavior.

Comparing Deep Learning and Reinforcement Learning

Contrasts exist between deep learning and reinforcement learning. While deep learning is dependent on a dataset for training and then applies what it has learnt to a new data set, reinforcement learning learns dynamically, altering behaviors to optimize a reward based on continuous feedback.

Applications of Deep Reinforcement Learning

Deep reinforcement learning finds applications in various sectors such as autonomous vehicles, manufacturing, healthcare, and bots. It ensures smooth navigation activities in self-driving cars and influences behaviour of intelligent robots in warehouses. In healthcare, it aids in medical diagnosis, treatment plans, clinical trials and automation of therapy. For AI bots, deep reinforcement enables rapid learning of language semantics in different fields for improved voice and natural language understanding.

Predicting the Future of Deep Reinforcement Learning

Predicting the future of deep reinforcement learning divides AI experts. Some argue that with time, energy, and the right rewards, the right RL architecture can tackle any problem, even achieving artificial general intelligence. Others dispute this by suggesting that, despite their benefits, deep reinforcement models need well-defined problems and can't discover new problems and solutions autonomously. Regardless, the importance and intriguing research possibilities of deep reinforcement learning in futurity for the AI community are undeniable.
