Recommender systems have become an integral part of the digital landscape, guiding users through an ever-growing sea of choices in e-commerce, streaming platforms, and social media. Traditionally powered by algorithms that rely on user-item interactions, these systems are increasingly being enhanced by Deep Reinforcement Learning (DRL). This article surveys the integration of DRL into recommender systems, examining its advantages, the challenges it addresses, and the new opportunities it presents. Why DRL for Recommender Systems? DRL is particularly well-suited for recommender systems due to its dynamic nature and ability to continuously learn and adapt from user interactions. Unlike static models that…

Reinforcement Learning (RL) is a powerful branch of artificial intelligence that focuses on teaching agents to make decisions by interacting with their environment. The effectiveness of an RL agent heavily relies on how well it can interpret its environment and actions. This is where the concepts of state and action parametrization play a pivotal role. State parametrization defines how an agent perceives its environment, while action parametrization determines the set of actions the agent can take. State Parametrization in Reinforcement Learning Importance of State Representation State parametrization is critical because it translates the vast complexities of the environment into a…

Safe reinforcement learning (RL) is a critical area of study that focuses on developing RL methods that not only perform effectively but also adhere to safety constraints to prevent undesirable or dangerous outcomes.

This article provides an overview of how constraints are formulated within the framework of safe RL, discussing the key types, challenges, and methodologies used in the field. Types of Safety Constraints Challenges in Safe RL Implementing safety constraints in RL poses several challenges. The…

Binary Neural Networks (BNNs) represent a significant advancement in the field of deep learning, tailored to enhance computational efficiency and reduce memory usage. By simplifying the data representation from floating-point precision to binary values (+1 or -1), BNNs facilitate faster computation and lower power consumption, making them ideal for resource-constrained devices like mobile phones and embedded systems. Core Principles of BNNs The fundamental concept behind BNNs lies in the binarization of both weights and activations within the neural network. Traditional neural networks utilize floating-point arithmetic for these parameters, which is computationally expensive and memory-intensive. In contrast, BNNs use binary values,…

Network computation in neural systems is a field at the intersection of neuroscience, cognitive science, and computer science. It involves studying how networks of neurons process information, communicate, and learn.
