Machine Learning in Smart Cities

 

Based on concepts in multivariate statistical Image result for smart city brainanalysis and optimization, we develop Machine Learning and Pattern Recognition techniques to process and analyze a large amount of information (Big Data) that lead to “intelligent” decision making. Ongoing applications include:

 

·        Photovoltaic power systems

·        Artisanal pisciculture

·        Precision agriculture

·        Water and air pollution analysis

·        Automatic sentiment and stress recognition and analysis

·        Nanotechnology and materials

·        Control of utility consumption patterns of residential consumers

·        Smart meter signal analysis

·        Crime dynamics

·        Healthcare systems

·        Detection of landmines in humanitarian demining

·        3D structure reconstruction in computer vision

·        Distributed and secure learning of pattern recognition systems

Design of Cooperation Networks in Multi Agent Systems

 

There are many complex processes whose behavior can be modeled and analyzed as the result of the interaction of simpler interconnected dynamical systems. Examples include power systems, cooperative autonomous vehicles, and human communities. We develop mathematical and computational tools for the design and control of such interactions, considering aspects such as stability, structured sparsity, vulnerability to attacks, and performance.

 

 

Data-driven Control of Dynamical Systems  

 

Many processes involve uncertainty that make their control a challenging task, especially when the control design method requires a model of the process that is known a priori. Based on concepts in Machine Learning, including Reinforcement Learning, we study and develop control strategies whose action depend on inferences made on the observed data. Ongoing projects include analysis and control of industrial processes, autonomous vehicles, and structures with active components in civil engineering.
