Reinforcement learning (RL) is a subfield of machine learning that deals with how an agent should learn to take actions in an environment to maximize some notion of cumulative reward. In other words, reinforcement learning is a learning paradigm where an agent learns to interact with an environment by taking actions and observing the feedback it receives in the form of rewards or penalties. It is a feedback-based Machine learning technique in which an agent learns to behave in an environment by performing the actions and seeing the results of actions. For each good action, the agent gets positive feedback, and for each bad action, the agent gets negative feedback or penalty.
In a very short time, deep learning has become a widely useful technique, solving and automating problems in computer vision, robotics, healthcare, physics, biology, and beyond. One of the delightful things about deep learning is its relative simplicity. Powerful deep learning software has been built to make getting started fast and easy. In a few weeks, you can understand the basics and get comfortable with the techniques. This opens up a world of creativity. You start applying it to problems that have data at hand, and you feel wonderful seeing a machine solving problems for you. However, you slowly feel yourself getting closer to a giant barrier. You built a deep learning model, but it doesn’t work as well as you had hoped. This is when you enter the next stage, finding and reading state-of-the-art research on deep learning. However, there’s a voluminous body of knowledge on deep learning, with three decades of theory, techniques, and tooling behind it. As you read through some of this research, you realize that humans can explain simple things in really complicated ways. Scientists use words and mathematical notation in these papers that appear foreign, and no textbook or blog post seems to cover the necessary background that you need in accessible ways. Engineers and programmers assume you know how GPUs work and have knowledge about obscure tools.

Real-time systems are computer systems that are designed to respond to external events within a specified time constraint. These systems are used in a variety of applications, including control systems, communication systems, multimedia systems, and embedded systems. Real-time systems must be able to respond to events in a timely and deterministic manner, meaning that the response time must be guaranteed and consistent. One of the main challenges in designing real-time systems is ensuring that they are predictable and reliable. Real-time systems must be able to handle a wide range of input conditions, from normal operation to extreme conditions, without crashing or failing to meet their deadlines. This requires careful design and implementation, as well as testing and verification to ensure that the system behaves as intended. Real-time systems often have unique requirements that differ from those of traditional computer systems. For example, real-time systems may need to operate in harsh environments, such as extreme temperatures or high radiation levels. They may also need to communicate with other systems in real-time, which requires low-latency communication protocols and high bandwidth. In addition to these technical challenges, there are also legal and ethical considerations when designing real-time systems. For example, systems used in safety-critical applications, such as medical devices or transportation systems, must meet strict regulatory requirements and undergo rigorous testing and certification processes. Overall, the design and implementation of real-time systems is a complex and challenging task that requires a deep understanding of the system's requirements, its environment, and the technologies available. In this textbook, we will explore the key concepts, principles, and techniques used in the design and analysis of real-time systems. We will cover topics such as scheduling, synchronization, communication, fault-tolerance, and performance analysis, and provide examples and case studies to illustrate these concepts. By the end of this book, readers will have a solid understanding of real-time systems and the skills needed to design and implement them effectively.
