DARPA ACTM (with BAE Systems)

Hybrid AI Integrating Koopman Units (HAIKU)

The HAIKU project leverages Koopman Operator methods to enhance existing state-of-the-art climate models for long-term predictions through the use of AI. The Koopman-based climate models offer improved predictions by modeling physics not accounted for in the climate models while exhibiting a speed-up of over a million times. These models allow climatologists to efficiently run simulations under different scenarios to improve the understanding of our planet’s weather system.

DARPA SBIR 

Koopman Operator-Based Forecasting for Nonstationary Processes from Near-Term, Limited Observational Data

We are developing a forecasting methodology that can be used with small amounts of data from possibly non-stationary sources, as opposed to traditional methodologies that require large data sets from stationary processes. The developed method can adapt to changes in the underlying process that generates the data. COVID-19 data is used as a test case for the methodology. We combine this forecasting technique with a control framework that makes recommendations on resource and patient distribution.

DARPA DITTO (with BAE and Synopsys)

Fast Accurate Surrogate Implementation, Modeling, and Integrated Learning Environment (FACSIMILE)

This project uses the Koopman operator framework for AI methods to surrogate functional ECUs. This is done so that these ECUs do not need to be fully simulated when testing new components under design. The Koopman surrogates allow faster simulation of these ECUs leading to a speed up during the design and testing of a new component.

Computational Advances in Operator Theoretic Approach to Dynamical Systems, with Application to Data Assimilation

In this project, we are planning to bring theoretical and numerical advances to the data assimilation methods by pursuing them in the operator-theoretic, probabilistic, and numerical linear algebra frameworks.

Koopman Mode Analysis of Spatially Extended Dynamical Systems with Applications to Agent-Based Models

This project focuses on extending the Koopman operator framework for AI to model spatially extended dynamical systems that possess a changing network topology. The optimization of neural networks has long been appreciated as being a dynamical system, but the complex way in which the architecture, data, and activation function affects the dynamics has made it difficult to study from such a perspective. Using advances in Koopman operator theory, we build data-driven, but theoretically backed, models that allow us to optimize, design, and analyze neural networks.

DARPA Combat (with BAE and UCSB)

Brigade AIs for TTP Learning and Evaluation via Behavioral Optimization of Tactics and Strategies (BATTLE BOTS)

We use Koopman operator theory to develop simulated game AI’s for real-time strategy games such as Starcraft. These AI’s can be played against to test and evaluate new player strategies, allowing us a vast data collection of different approaches to real-world battle.

Network Security with MixMode  

Koopman Mode Analysis

AIMdyn has developed an AI system for use in network security. Koopman operator models of streams of data are used to provide generative models of the dynamics, based on which anomalous behavior on the network is detected. Such anomalous behavior is correlated using AI to provide the analyst with detailed information of malicious behavior on their network, enabling them to mitigate the threat
