DESCRIPTION:Speakers: Jing Chen (Flatiron Institute)\nTensor network is bo
th a theoretical and numerical tool\, which has achieved great success in
many body physics from calculating he thermodynamic property and quantum p
hase transition to simulations of black holes. As a general form of high d
imensional data structure\, tensors have been adopted in diverse branches
of data analysis\, such as in signal and image processing\, psychometric\,
quantum chemistry\, biometric\, quantum information\, back holes\, and br
ain science. Tensor network simulates the interactions between tensors and
becomes a developing powerful in these new fields. During recent years\,
tensor network numerical methods such as matrix product state (MPS) and pr
ojected entangled pair state (PEPS) has also finds its way to machine lear
ning. Besides\, the physical concept of entanglement offers a new theoret
ical approach to the design of different neural networks. \nFor example\,
we find that graphic models\, such as restricted Boltzmann machine (RBM) i
s equivalent to a specific tensor network and we can study the expression
power of the RBM.\n\nPhys. Rev. B 97\, 085104 (2018)\narXiv: 1712.04144\n\

DESCRIPTION:Speakers: Cedric Beny (Hanyang University)\nOur understanding
of any given complex physical system is made of not just one\, but many th
eories which capture different aspects of the system. These theories are o
ften stitched together only in informal ways. An exception is given by ren
ormalization group techniques\, which provide formal ways of hierarchicall
y connecting descriptions at different scales.\n\nIn machine learning\, th
e various layers of a deep neural network seem to represent different leve
ls of abstraction. How does this compare to scale in renormalization? Can
one build a common information-theoretic framework underlying those techni
ques? \n\nTo approach these questions\, I compare two different renormali
zation techniques (which emerged from quantum information theory)\, and at
tempt to adapt them to unsupervised learning tasks. One approach\, MERA\,
superficially resembles a deep convolutional neural net\, while another ap
proach based on dimensional reduction yields something similar to principa
l component analysis.\n\nhttps://indico.cern.ch/event/704438/contributions

DESCRIPTION:Speakers: Koji Hashimoto (Osaka University)\nWe present a deep
neural network representation of the AdS/CFT correspondence\, and demonst
rate the emergence of the bulk metric function via the learning process fo
r given data sets of response in boundary quantum field theories. The emer
gent radial direction of the bulk is identified with the depth of the laye
rs\, and the network itself is interpreted as a bulk geometry. Our network
provides a data-driven holographic modeling of strongly coupled systems.
With a scalar ϕ4 theory with unknown mass and coupling\, in unknown curve
d spacetime with a black hole horizon\, we demonstrate our deep learning (
DL) framework can determine them which fit given response data. First\, we
show that\, from boundary data generated by the AdS Schwarzschild spaceti
me\, our network can reproduce the metric. Second\, we demonstrate that ou
r network with experimental data as an input can determine the bulk metric
\, the mass and the quadratic coupling of the holographic model. As an exa
mple we use the experimental data of magnetic response of a strongly corre
lated material Sm0.6Sr0.4MnO3. This AdS/DL correspondence not only enables
gravity modeling of strongly correlated systems\, but also sheds light on
a hidden mechanism of the emerging space in both AdS and DL.\n(Work in co

DESCRIPTION:Speakers: Akinori Tanaka (Riken)\nRecent development of machin
e learning (ML)\, especially deep learning is remarkable. It has been appl
ied to image recognition\, image generation and so on with very good preci
sion. From a mathematical point of view\, images are just real matrices\,
so it would be a natural idea to replace this matrices with the configurat
ions of the physical system created by numerical simulation and see what h
appens. In this talk\, I will review our attempt to reduce autocorrelation
of Hamiltonian Monte Carlo (HMC) algorithm. In addition\, I would like to
discuss a possibility of using recent sophisticated generative models lik
e VAE\, GAN to improve HMC. (work in collaboration with A. Tomiya\, arXiv:

DESCRIPTION:Speakers: Hiroyu Fujita (University of Tokyo)\nHandling the la
rge number of degrees of freedom with proper approximations\, namely the c
onstruction of the effective Hamiltonian is at the heart of the (condensed
matter) physics. Here we propose a simple scheme of constructing Hamilton
ians from given energy spectrum. The sparse nature of the physical Hamilto
nians allows us to formulate this as a solvable supervised learning proble
m. Taking a simple model of correlated electron systems\, we demonstrate t
he data-driven construction of its low-energy effective model. Moreover\,
we find that the same approach works for the construction of the entangle
ment Hamiltonian of a given quantum many-body state from its entanglement
spectrum. Compared to the known approach based on the full diagonalization
of the reduced density matrix\, our one is computationally much cheeper t
hus offering a way of studying the entanglement nature of large (sub)syste
ms under various boundary conditions.\n\nhttps://indico.cern.ch/event/7044

DESCRIPTION:Speakers: Yi-Zhuang You (UCSD & Harvard)\nMotivated by the clo
se relations of the renormalization group with both the holography duality
and the deep learning\, we propose that the holographic geometry can emer
ge from deep learning the entanglement feature of a quantum many-body stat
e. We develop a concrete algorithm\, call the entanglement feature learnin
g (EFL)\, based on the random tensor network (RTN) model for the tensor ne
twork holography. We show that each RTN can be mapped to a Boltzmann machi
ne\, trained by the entanglement entropies over all subregions of a given
quantum many-body state. The goal is to construct the optimal RTN that bes
t reproduce the entanglement feature. The RTN geometry can then be interpr
eted as the emergent holographic geometry. We demonstrate the EFL algorith
m on 1D free fermion system and observe the emergence of the hyperbolic ge
ometry (AdS_3 spatial geometry) as we tune the fermion system towards the
gapless critical point (CFT_2 point).\n\nhttps://indico.cern.ch/event/7044
