Is AI currently capable of identifying wild oysters? A comparison of human annotators against the AI model, ODYSSEE
Brendan Campbell, Alan Williams, Kleio Baxevani +11
Oysters are ecologically and commercially important species that require frequent monitoring to track population demographics (e.g. abundance, growth, mortality). Current methods o…
MPC and System Identification with Differentiable Physics: Fluid System and Particle Beam Control
Alan Williams, Alp Sunol
We consider the problem of simultaneous control and parameter estimation when the model is available only as a differentiable physics simulator. We propose a receding-horizon contr…
Nested Extremum Seeking Converges to Stackelberg Equilibrium
Brad Ratto, Alan Williams, Miroslav KrstiÄ +2
The nested Extremum Seeking (nES) algorithm is a model-free optimization method that has been shown to converge to a neighborhood of a Nash equilibrium. In this work, we demonstrat…
Random Walks for Spike-Timing Dependent Plasticity
Alan Williams, Todd K. Leen, Patrick D. Roberts
Random walk methods are used to calculate the moments of negative image equilibrium distributions in synaptic weight dynamics governed by spike-timing dependent plasticity (STDP).…
Adaptive conditional latent diffusion maps beam loss to 2D phase space projections
Alexander Scheinker, Alan Williams
Beam loss (BLM) and beam current monitors (BCM) are ubiquitous at particle accelerator around the world. These simple devices provide non-invasive high level beam measurements, but…
-detachable pairs in 3-connected matroids I: unveiling
Nick Brettell, Geoff Whittle, Alan Williams
Let be a 3-connected matroid, and let be a 3-connected minor of . We say that a pair is -detachable if one of the matroids or…
