[Turing-Southampton] TODAY at 12 noon | Turing at Southampton Seminar and Networking Lunch

[Susan Davies]

***apologies if you receive this more than once***

A reminder of our first Turing at Southampton Seminar today at 12 noon, following by a networking lunch from 1pm.  Details below:

Speaker:              Shotaro Shiba-Funai, Okinawa Institute of Science and Technology

Date:                    Friday 17 January 2020, 12.00 noon

Location:             Building 46/5081

Title:                    Feature extraction by machine learning and its related physics

Abstract:

Unsupervised machine learning is generally useful to extract features of input data. Since it can be regarded as a kind of information compression, some researchers suggest its similarity to coarse-graining and renormalization.

In this talk, we use spin configurations of Ising model as the input data and restricted Boltzmann machine (RBM) as the method of unsupervised learning. Then we look at what kind of features the machine extracts, using our method of “RBM flow”.  ​As a result, we can find an interesting similarity to renormalization and some coincidence with thermodynamics. However, we also discover apparent differences from renormalization and then argue why such phenomena occur by studying the parameter dependence in machine learning.​

Best wishes
