Estimados(as) Académicos y Alumnos,

Se les invita para el próximo martes 16 de abril, a 2 sesiones del 
seminario *Seminario doble conjunto Modelamiento Estocástico / Núcleo 
Milenio MESCYD*, el cual tendrá lugar en la sala de seminarios John Von 
Neumann del CMM, séptimo piso, torre norte, de Beauchef 851.

*Primera Sesión: 3pm*

Avelio Sepúlveda (U. Lyon 1)

*Liouville dynamical percolation*

A dynamical percolation is a process on black and white colourings of 
the vertices of a graph, in which each vertex has an independent 
Poissonian clock, and each time a clock rings the colour of its 
correspondent vertex is resampled. In this talk, we will study a 
dynamical percolation in the triangular grid, using clocks whose rate is 
defined in terms of a Liouville measure of parameter $\gamma$. In 
particular, we will show that this dynamic converges, in the scaling 
limit, to a càdlàg process that undergoes a phase transition when 
$\gamma=\sqrt{5/2}$.

Joint work with C. Garban, N. Holden and X. Sun.

*Segunda Sesión: 4pm*

Nikolas Tapia (Norwegian U. of Science and Technology)

*The signature method*

Introduced by Chen and then generalised by Lyons, signatures have found 
a wide number of applications in Machine Learning and Data Analysis in 
recent years.

On the first half of this talk I will give a brief introduction to the 
subject and describe some of the applications existing in the literature.

On the second half, I will discuss current work-in-progress (joint with 
E. Celledoni and P. E. Lystad) on an application of the signature method 
to motion recognition in computer animation.
