Every artificial intelligence(AI) problem is a new universe of complexities and unique challenges. Very often, the most challenging aspects of solving an AI problem is not about finding a solution but understanding the problem itself. As paradoxically as that sounds, even the most experienced AI experts have been guilty of rushing into proposing deep learning algorithms and exoteric optimization techniques without fully understanding the problem at hand. When we think about an AI problem, we tend to link our reasoning to two main aspects: datasets and models. However, that reasoning is ignoring what can be considered the most challenging aspect of an AI problem: the environment.

What if I would tell you that Language Models and Multi-Agent Reinforcement learning are now engaged and will get married soon? First and foremost, kudos to Andrés Fernández Rodríguez who sent me the inspiring paper "Multi-Agent Reinforcement Learning is a Sequence Modeling Problem". The idea of the paper is fantastic. In its essence, it is about mapping the problem of agent control to token translation. The authors use an encoder-decoder model like the original "Attention is all you need" paper.

As artificial intelligence gets better at performing tasks once solely in the hands of humans, like driving cars, many see teaming intelligence as a next frontier. In this future, humans and AI are true partners in high-stakes jobs, such as performing complex surgery or defending from missiles. But before teaming intelligence can take off, researchers must overcome a problem that corrodes cooperation: humans often do not like or trust their AI partners. MIT Lincoln Laboratory researchers have found that training an AI model with mathematically "diverse" teammates improves its ability to collaborate with other AI it has never worked with before, in the card game Hanabi. Moreover, both Facebook and Google's DeepMind concurrently published independent work that also infused diversity into training to improve outcomes in human-AI collaborative games.

Cooperative multi-agent reinforcement learning (MARL) is making rapid progress for solving tasks in a grid world and real-world scenarios, in which agents are given different attributes and goals, resulting in different behavior through the whole multi-agent task. In this study, we quantify the agent's behavior difference and build its relationship with the policy performance via {\bf Role Diversity}, a metric to measure the characteristics of MARL tasks. We define role diversity from three perspectives: action-based, trajectory-based, and contribution-based to fully measure a multi-agent task. Through theoretical analysis, we find that the error bound in MARL can be decomposed into three parts that have a strong relation to the role diversity. The decomposed factors can significantly impact policy optimization on three popular directions including parameter sharing, communication mechanism, and credit assignment. The main experimental platforms are based on {\bf Multiagent Particle Environment (MPE)} and {\bf The StarCraft Multi-Agent Challenge (SMAC). Extensive experiments} clearly show that role diversity can serve as a robust measurement for the characteristics of a multi-agent cooperation task and help diagnose whether the policy fits the current multi-agent system for a better policy performance.

Be sure to check out his talk, "Digital Twins: Not All Digital Twins are Identical," there! As we try to bridge the gap between digital and physical systems, we increasingly hear about "digital twins." Like many other concepts (e.g., Artificial Intelligence or Metaverse) the term "digital twins" can mean very different things to different people. For some, a digital twin is intimately associated with the Internet of Things (IoT) and is the digital equivalent of a sensor or a physical asset (e.g, an aircraft engine). It allows them to experiment with the digital version that they may not be able to do with the physical system.

COMPUTEX TAIPEI, one of the world's largest computer trade shows, took place physically and virtually this year from May 24-May 27, alongside the 2-week COMPUTEX DigitalGo Online Exhibition organized by TAITRA. CK Tseng, President of ARM Taiwan, addressed how the ICT industry – more specifically ARM Technology -- can turn the challenges of the pandemic into opportunities to create a better future with digital technologies during the kickoff COMPUTEX 2022 Global Press Conference held with a panel of tech leaders at the Taipei Nangang Exhibition Center. Tseng weighed in specifically on the pandemic's impact on the tech industry. "When encountered with a situation like this, you will regret it if you did not set up lights out factories, unmanned warehouses, or smart retail. Such use cases require a lot of computing and AI. ARM, as the most progressive computing platform, needs to find a new way to serve our partners who already employ our solutions – from AI sensors in the Amazon rainforest to track animal behaviors to the data processing units installed in data centers."

This work is concerned with the problem of planning trajectories and assigning tasks for a Multi-Agent System (MAS) comprised of differential drive robots. We propose a multirate hierarchical control structure that employs a planner based on robust Model Predictive Control (MPC) with mixed-integer programming (MIP) encoding. The planner computes trajectories and assigns tasks for each element of the group in real-time, while also guaranteeing the communication network of the MAS to be robustly connected at all times. Additionally, we provide a data-based methodology to estimate the disturbances sets required by the robust MPC formulation. The results are demonstrated with experiments in two obstacle-filled scenarios

Factored decentralized Markov decision process (Dec-MDP) is a framework for modeling sequential decision making problems in multi-agent systems. In this paper, we formalize the learning of numerical methods for hyperbolic partial differential equations (PDEs), specifically the Weighted Essentially Non-Oscillatory (WENO) scheme, as a factored Dec-MDP problem. We show that different reward formulations lead to either reinforcement learning (RL) or behavior cloning, and a homogeneous policy could be learned for all agents under the RL formulation with a policy gradient algorithm. Because the trained agents only act on their local observations, the multi-agent system can be used as a general numerical method for hyperbolic PDEs and generalize to different spatial discretizations, episode lengths, dimensions, and even equation types.
