Reinforcement learning (RL) offers a distinct approach to AI/ML compared to supervised and unsupervised learning, making it the preferred choice for certain applications where the optimal solution is not known or cannot be easily obtained, such as in robotics or financial markets. Additionally, RL can handle non-stationary environments where the distribution of data changes over time, unlike supervised learning which requires a fixed dataset. Supervised and unsupervised learning are limited to learning from labeled data or finding patterns in unlabeled data. RL on the other hand involves a model receiving a reward or penalty based on the long-term consequences of its actions, allowing it to learn in complex and uncertain environments. RL is a streaming learning method as well (as opposed to batch), making it well-suited to changing environments, and has shown promise in enabling intelligent decision-making. Its unique characteristics and potential applications make it an exciting area of machine learning.

However, while RL presents unique benefits it comes along with challenges. Challenges include being able to easily select an appropriate model, transparent model decisions, and easily scaled models as data size and complexity increases. To address these challenges, various new platforms and tools have emerged, boasting powerful compute engines that can improve scalability, the flexibility to support multiple machine learning frameworks, and ensure model observability for accurate results. While deploying RL models can be challenging, the benefits it offers to enterprises in different industries can be realized through the right techniques, platforms, and tools driving success in various applications.

Addressing the challenges to reinforcement learning in real world applications

An example of the lack of interpretability of RL models can be seen in the field of robotics where RL is often used to train models to perform tasks such as grasping objects, walking, and navigating environments. The models can be difficult to interpret as they often involve complex interactions between the model and the environment, as well as multiple layers of neural networks. In addition, RL models can be highly dependent on the training data, which makes it difficult to generalize the model to new situations. This is particularly true in situations where the environment is highly dynamic and unpredictable, as the model may not have encountered all possible scenarios during training. An example of this is seen in algorithmic trading where RL is used to develop models that learn to make trading decisions based on market data. However, market movements can sometimes fall outside of the historical trading data, and the models may not be able to generalize these new situations. This can lead to difficulty in interpreting the model’s decision-making process. Observability and data validation capabilities can help improve these issues as observability provides insight into the model’s behavior and can help identify potential performance issues. Data validation can ensure the model is trained on high-quality data. A platform with these features can help address the challenges of interpreting RL models in complex and dynamic environments.

The selection of the right RL model can be a challenging task as well, and choosing the wrong one can result in poor performance or even failure. There are many types of RL models, each with its own strengths and weaknesses. For example, Q-learning and SARSA are appropriate for problems with small state spaces and discrete actions, while DQN is more suited to problems with large state spaces and continuous actions. In small state problems, there are a limited number of possible states for the model to evaluate and determine the best action to take, but large state problems have a much larger number of states, increasing the difficulty for the model’s evaluation significantly. An example of a small state problem includes games like chess, where there’s a limited number of possible configurations. However, problems such as those facing autonomous driving models, where the car must react to changing traffic conditions would be considered a large state problem. Therefore some algorithms may perform poorly on certain problems or may require large amounts of data to learn effectively. Certain deployment platforms enable compatibility with multiple ML frameworks, which allows data scientists to use the best framework and library for the problem, instead of artificially limiting the tools available at a data scientist’s disposal to only what is supported by a deployment platform. This compatibility allows users to choose from a variety of RL models. Furthermore, access to a range of models can help users experiment and select the one that is best suited to their specific problem, which can help to ensure that the selected model performs well and learns effectively.

RL can also become computationally expensive as the state and action spaces increase in size, making it difficult to learn optimal policies for problems with large or continuous state and action spaces. This lack of scalability can limit the applicability of RL to real-world problems and make it difficult to scale to larger problems. The computational cost of learning an optimal policy can increase significantly with the size of the state and action spaces, making RL impractical for large problems. Deep reinforcement learning (DRL), in particular, can require large amounts of data to train effectively, and the computational cost can be high, making it challenging to scale to large problems. For instance, DRL has been used to optimize wind turbine performance, and the large state and action spaces made the problem difficult to solve using RL. Options such as using a Rust compute engine can address these scalability issues since it is a programming language suited for high-performance computing tasks due to its speed, reliability, and low-level control. This can make RL more practical for larger problems with high computational cost. Moreover, the use of Rust can also aid in the scalability of deep reinforcement learning (DRL) models by enabling the processing of large datasets quickly and efficiently.
