This study presents an integrated approach to understanding epidemic dynamics through a stochastic spatio-temporal simulation model on a multiplex network, blending physical and informational layers. The physical layer maps the geographic movement of individuals, while the information layer tracks the spread of knowledge and health behavior via social interactions. We explore the interplay between physical mobility, information flow, and epidemic outcomes by simulating disease spread within this dual-structured network. Our model employs stochastic elements to mirror human behavior, mobility, and information dissemination uncertainties. Through simulations, we assess the impact of network structure, mobility patterns, and information spread speed on epidemic dynamics. The findings highlight the crucial role of effective communication in curbing disease transmission, even in highly mobile societies. Additionally, our agent-based simulation allows for real-time scenario analysis through a user interface, offering insights into leveraging physical and informational networks for epidemic control. This research sheds light on designing strategic interventions in complex social systems to manage disease outbreaks.

The distributed coordination of robot teams performing complex tasks is challenging to formulate. The different aspects of a complete task such as local planning for obstacle avoidance, global goal coordination and collaborative mapping are often solved separately, when clearly each of these should influence the others for the most efficient behaviour. In this paper we use the example application of distributed information acquisition as a robot team explores a large space to show that we can formulate the whole problem as a single factor graph with multiple connected layers representing each aspect. We use Gaussian Belief Propagation (GBP) as the inference mechanism, which permits parallel, on-demand or asynchronous computation for efficiency when different aspects are more or less important. This is the first time that a distributed GBP multi-robot solver has been proven to enable intelligent collaborative behaviour rather than just guiding robots to individual, selfish goals.

Since data is at the heart of AI, it should come as no surprise that AI and ML systems need enough good quality data to "learn". In general, a large volume of good quality data is needed, especially for supervised learning approaches, in order to properly train the AI or ML system. The exact amount of data needed may vary depending on which pattern of AI you're implementing, the algorithm you're using, and other factors such as in house versus third party data. For example, neural nets need a lot of data to be trained while decision trees or Bayesian classifiers don't need as much data to still produce high quality results. So you might think more is better, right?

Machine learning (ML) and artificial intelligence (AI) have revolutionized industries and our daily lives; they help video-streaming services predict which movies we'd like to watch, allow credit card companies to identify fraudulent transactions and enable navigation apps to find the fastest routes to our destinations. For geospatial applications, AI and ML can identify objects and patterns automatically and derive meaningful insights from satellite imagery in hours--a task that previously would have required teams of analysts and months of effort. With these tools, we can gain insights about any spot on the globe, identify where things are changing most quickly and find patterns that have never before been visible in data. In machine learning, a form of AI, computer programs improve through experience, accessing data and using it to learn for themselves. Algorithms with richer data will become more effective in nature.
