GOD model: Privacy Preserved AI School for Personal Assistant
PIN AI Team, Bill Sun, Gavin Guo +7
Personal AI assistants (e.g., Apple Intelligence, Meta AI) offer proactive recommendations that simplify everyday tasks, but their reliance on sensitive user data raises concerns a…
Optimal control for diffusions on graphs
Laura Florescu, Yuval Peres, Miklos Z. Racz
Starting from a unit mass on a vertex of a graph, we investigate the minimum number of "\emph{controlled diffusion}" steps needed to transport a constant mass outside of the ba…
Spectral Thresholds in the Bipartite Stochastic Block Model
Laura Florescu, Will Perkins
We consider a bipartite stochastic block model on vertex sets and , with planted partitions in each, and ask at what densities efficient algorithms can recover the parti…
Heat diffusion with frozen boundary
Laura Florescu, Shirshendu Ganguly, Yuval Peres +1
Consider "Frozen Random Walk" on : particles start at the origin. At any discrete time, the leftmost and rightmost particles are "froz…
The range of a rotor walk
Laura Florescu, Lionel Levine, Yuval Peres
In a \emph{rotor walk} the exits from each vertex follow a prescribed periodic sequence. On an infinite Eulerian graph embedded periodically in , we show that any simple roto…
Sandpiles and Dominos
Laura Florescu, Daniela Morar, David Perkinson +2
We consider the subgroup of the abelian sandpile group of the grid graph consisting of configurations of sand that are symmetric with respect to central vertical and horizontal axe…
Escape rates for rotor walk in Z^d
Laura Florescu, Shirshendu Ganguly, Lionel Levine +1
Rotor walk is a deterministic analogue of random walk. We study its recurrence and transience properties on Z^d for the initial configuration of all rotors aligned. If n particles…
Derivation of Radiation from a Dipole immersed in a Homogenous Magnetized Plasma
Laura Florescu
We are considering a dipole antenna immersed in cold plasma and investigate its radiation patterns. We are solving Maxwell's equations using (1) analytic solutions for the case whe…
