Aimdyn inc. competed for and won a competitive Request for Proposal to work with The Defense Advanced Research Projects Agency (DARPA) on Artificial Intelligence technology.

They have chosen to work with Aimdyn because of the company’s vast history with processing and managing this type of big data for applications in machine learning and artificial intelligence. 

“Between DOD’s security and performance requirements, the immaturity of the technology to deal with unstructured and incomplete data and the complex problems that come with modeling dynamic systems, integration of AI into defense applications has been slow,” read an article from GCN. 

“To speed the adoption of AI, the Defense Advanced Research Projects Agency is issuing a Disruption Opportunity — a call for innovative basic research concepts exploring new architectures and approaches to improve AI’s ability to generalize beyond training data and work with sub-optimal data,” it said.

AIMdyn Founder Dr. Igor Mezic Featured in UCSB Article on Transportation

The UCSB Currant reads;

“For most of us, fluid dynamics and mechanics aren’t particularly significant — that is, until we’re white-knuckling it on a bumpy plane ride or trying to stay buoyant in unusually bubbly water. The way we navigate through air and water may one day be improved thanks to UC Santa Barbara researchers studying the complex properties and interactions of fluids.

Fueled by multiple Multi-University Research Initiative (MURI) grants from the U.S. Department of Defense’s Office of Naval Research, the UCSB scientists may also gain insight into some of classical physics’ greatest mysteries.”

In regards to our founder, Dr. Igor Mezic, the Currant wrote:

“When you take a walk, a multitude of remarkable things happen in your body to keep you upright, balanced and moving forward.

‘You’re actually falling,’ said UCSB mechanical engineer Igor Mezic. ‘In the second or so that occurs between steps, you sense your body moving ahead and down, but break your fall when your forward foot lands. Your weight shifts and muscles contract to maintain locomotion while other muscles relax. Your feet and legs compensate for unevenness of terrain. Your eyes can map out the path ahead; your ears may sense the area around you. Your body can twist and bend around obstacles or avoid things coming your way, or even take action should you trip to minimize or prevent damage. If you’re carrying something your entire body will redistribute its balance and use of muscles to accommodate the object.’

Koopman Spectrum for Cascaded Systems

This paper was co-written by our founder and lead-scientist, Igor Mezic along with Aimdyn scientist and colleague, Ryan Mohr.

Abstract:

This paper considers the evolution of Koopman principal eigenfunctions of cascaded dynamical sys- tems. If each component subsystem is asymptotically stable, the matrix norms of the linear parts of the component subsystems are strictly increasing, and the component subsystems have disjoint spectrums, there exist perturbation functions for the initial conditions of each component subsystem such that the orbits of the cascaded system and the decoupled component subsystems have zero asymptotic relative error. This implies that the evolutions are asymptotically equivalent; cascaded compositions of stable systems are stable. These results hold for both cascaded systems with linear component subsystem dy- namics and linear coupling terms and nonlinear cascades topologically conjugate to the linear case. We further show that the Koopman principal eigenvalues of each component subsystem are also Koopman eigenvalues of the cascaded system. The corresponding Koopman eigenfunctions of the cascaded system are formed by extending the domain of definition of the component systems’ principal eigenfunctions and then composing them with the perturbation function.

AIMdyn Scientists Analyze Data Driven Modal Decompositions

The Dynamic Mode Decomposition (DMD) is a tool of trade in computational data driven analysis of fluid flows. More generally, it is a computational device for Koopman spectral analysis of nonlinear dynamical systems, with a plethora of applications in applied sciences and engineering. Its exceptional performance triggered developments of several modifications that make the DMD an attractive method in data driven framework. This work offers further improvements of the DMD to make it more reliable, and to enhance its functionality. In particular, data driven formula for the residuals allows selection of the Ritz pairs, thus providing more precise spectral information of the underlying Koopman operator, and the well-known technique of refining the Ritz vectors is adapted to data driven scenarios. Further, the DMD is formulated in a more general setting of weighted inner product spaces, and the consequences for numerical computation are discussed in detail. Numerical experiments are used to illustrate the advantages of the proposed method, designated as DDMD_RRR (Refined Rayleigh Ritz Data Driven Modal Decomposition).

Aimdyn Named a Top Program by Air Force Office of Scientific Research

Aimdyn was recently listed in the Air Force Office of Scientific Research’s publication as one of their top research programs from 1951 to present day.

The honor was bestowed upon Aimdyn after a research project led by Aimdyn founder Dr. Igor Mezic directly assisted in the discovery of new methods for passive mitigation of thermoacoustic instabilities in jet engines.

This and other related successes were foundational in forming the UTRC, UCSB. Caltech, Stanford, Princeton, Yale, PlainSight and Aimdyn team that won a 2006 DARPA project where 40 researchers attempted to use new methods or ergodic theory, operator theory, and spectral graph theory to develop methodology and tools for analysis and design of complex dynamical systems robust to uncertainty.

Major a accomplishments of the project were new methods for quantifying uncertainty in dynamical systems that were much faster than previous known methods as well as the discovery of new, efficient unmanned aerial vehicle search methods that had near-linear scaling in system size.

These methods are currently being used in UTRC’s Autonomous and Intelligent Systems program.
