SUMMARY:Simons Collaboration on Homological Mirror Symmetry
DESCRIPTION:The Simons Collaboration on Homological Mirror Symmetry brings together a group of leading mathematicians working towards the goal of proving Homological Mirror Symmetry (HMS) in full generality\, and fully exploring its applications. This program is funded by the Simons Foundation. \nMirror symmetry\, which emerged in the late 1980s as an unexpected physical duality between quantum field theories\, has been a major source of progress in mathematics. At the 1994 ICM\, Kontsevich reinterpreted mirror symmetry as a deep categorical duality: the HMS conjecture states that the derived category of coherent sheaves of a smooth projective variety is equivalent to the Fukaya category of a mirror symplectic manifold (or Landau-Ginzburg model). \nWe envision that our goal of proving HMS in full generality can be accomplished by combining three main viewpoints: \n\ncategorical algebraic geometry and non-commutative (nc) spaces: in this language\, homological mirror symmetry is the statement that the same nc-spaces can arise either from algebraic geometry or from symplectic geometry.\nthe Strominger-Yau-Zaslow (SYZ) approach\, which provides a global geometric prescription for the construction of mirror pairs.\nLagrangian Floer theory and family Floer cohomology\, which provide a concrete path from symplectic geometry near a given Lagrangian submanifold to an open domain in a mirror analytic space.\n\nThe Center of Mathematical Sciences and Applications is hosting the following short-term visitors for an HMS focused semester: \n\nJacob Bourjaily (Neils Bohr Institute)  4/1/2018 – 4/14/2018\nColin Diemer (IHES)  2/25/2018 – 3/10/2018\nCharles Doran (University of Alberta) 5/13/2018 – 5/25/2018\nBaohua Fu (Chinese Academy of Sciences)  4/15/2018 – 4/28/2018\nAndrew Harder (University of Miami)  4/15/2018 – 4/28/2018\nShinobu Hosono (Gakushuin University) 2/25/2018 – 3/10/2018\nAdam Jacob (UC Davis) 3/5/2018 – 3/16/2018\nTsung-Ju Lee (National Taiwan University) 4/18/2018 – 5/13/2018\nIvan Loseu (Northeastern University) 1/21/2018 – 2/3/2018\nCheuk-Yu Mak (Cambridge University) 4/1/2018 – 4/15/2018\nDaniel Pomerleano (Imperial College) 3/19/2018 – 3/23/2018\nMauricio Romo (Tsinghua University) 4/1/2018 – 4/18/ 2018\nEmanuel Scheidegger (Albert Ludwigs University of Freiburg) 2/22/2018 – 3/22/2018\nDmytro Shklyarov (Technische Universität Chemnitz) 3/4/2018 – 3/17/2018\nAlan Thompson (University of Cambridge) 4/15/2018 – 4/21/2018\nWeiwei Wu (University of Georgia) 4/27/2018 – 5/6/2018\nMatt Young (Chinese University of Hong Kong) 1/15/2018 – 2/9/2018\nJeng-Daw Yu (National Taiwan University) 4/2/2018 – 4/6/2018\nMinxian Zhu (Yau Mathematical Sciences Center\, Tsinghua University) 1/ 22/2018 – 2/25/2018\n\nAs part of their CMSA visitation\, HMS focused visitors will be giving lectures on various topics related to Homological Mirror Symmetry throughout the Spring 2018 Semester.  Click here for information. \n\n\nThe Collaboration will include two workshops hosted by The Center.

SUMMARY:A Mean Field View of the Landscape of Two-Layers Neural Networks
DESCRIPTION:Speaker: Andrea Montanari (Stanford) \nTitle: A Mean Field View of the Landscape of Two-Layers Neural Networks \nAbstract: Multi-layer neural networks are among the most powerful models in machine learning and yet\, the fundamental reasons for this success defy mathematical understanding. Learning a neural network requires to optimize a highly non-convex and high-dimensional objective (risk function)\, a problem which is usually attacked using stochastic gradient descent (SGD). Does SGD converge to a global optimum of the risk or only to a local optimum? In the first case\, does this happen because local minima are absent\, or because SGD somehow avoids them? In the second\, why do local minima reached by SGD have good generalization properties? We consider a simple case\, namely two-layers neural networks\, and prove that –in a suitable scaling limit– the SGD dynamics is captured by a certain non-linear partial differential equation. We then consider several specific examples\, and show how the asymptotic description can be used to prove convergence of SGD to network with nearly-ideal generalization error. This description allows to ‘average-out’ some of the complexities of the landscape of neural networks\, and can be used to capture some important variants of SGD as well.
