DESCRIPTION:Prof. Simone Deparis\nModeling and simulations of vascular flo
 ws: reduced order modeling and physics based neural networks.\n\nAbstract:
 \nWe are interested in the approximation of vascular flows modeled by para
 metrized partial differential equations\, when the value of the physical p
 arameters is unknown or difficult to be directly measured. We aim at estim
 ating the flows field or other quantities of clinical interest by combinin
 g reduced order modeling with neural networks. The reduced order model acc
 ounts for the underlying physical phenomenon and allows for generating a l
 arge test set for the training of the neural network. The snapshots are ob
 tained from randomly selected values of the physical parameters during an 
 expensive offline phase. The chosen DNN architecture resembles an asymmetr
 ic autoencoder in which the decoder is the reduced orde model solver and i
 t does not contain trainable parameters.\nWe present few examples of our m
 ethod in applications related to vascular flows and electrophysiology\, wh
 ere the neural network is able to approximately identify the physical para
 meters or clinical indices.\n\nBio:\nSimone Deparis is Adjunct Professor i
 n Mathematics and deputy director of the Section of Mathematics. His resea
 rch  focuses on scientific computing and numerical analysis applied to ha
 emodynamics\, but he also studies reduced order models for the Navier-Stok
 es equations and blood flow. Recently he has begun to investigate the inte
 rplay between reduced basis and neural network approaches for parametrised
  PDEs.  The Center for Intelligent Systems at EPFL (CIS) is a collabora
 tion among IC\, SB\, and STI that brings together researchers working on d
 ifferent aspects of Intelligent Systems.\n---\nThe Center for Intelligent 
 Systems at EPFL (CIS) is a collaboration between IC\, SB\, STI and ENAC th
 at brings together researchers working on different aspects of intelligent
  systems.\nIn order to promote exchanges among researchers and encourage t
 he creation of new\, collaborative projects\, CIS is organizing a "Get to 
 know your neighbors" series. Each seminar will consist of 1-2 short overvi
 ew presentations geared to the general public at EPFL.\n \nOur second sem
 inar will take place live on Zoom: https://epfl.zoom.us/j/95904377229\n \
 nMonday\, 5th October 2020 from 3:15 to 4:15 pm\n\n\nNB: Video recordings 
 of the seminars will be made available on our website and published on our
  social media pages
