Programme Schedule of the Invited Lectures:
Time: 10.05 – 11.05 AM (IST)
Speaker: Prof Vineeth N Balasubramanian (IIT Hyderabad)
Title: Explainable Deep Learning: Overview, Trends and Challenges
Abstract: The last decade has seen rapid strides in Artificial Intelligence (AI) moving from being a fantasy to a reality that is a part of each one of our lives, embedded in various technologies. A catalyst of this rapid uptake has been the enormous success of deep learning methods for addressing problems in various domains including computer vision, natural language processing, and speech understanding. However, as AI makes its way into risk-sensitive and safety-critical applications such as healthcare, aerospace and finance, it is essential for AI models to not only make predictions but also be able to explain their predictions. This talk will introduce the audience to this increasingly important area of explainable AI, describe salient methods in explainable deep learning, discuss open challenges as well as present some of our recent research in this domain.
Time: 11.30 AM – 12.30 PM (IST)
Speaker: Dr Girish Varma (IIIT Hyderabad)
Title: Deep Generative Methods and Applications
Abstract: Generative methods deals with the modelling of complex high dimensional probability distributions. With the advent of deep neural networks, these methods have become more common with the discovery of new techniques like GANs. Such methods can learn to generate images, graphs etc even without using labelled data. In this talk, we will give some of the common deep generative modelling techniques like GANs, Variational Autoencoders, Normalizing Flows. We will also look at some example applications in Style Transfer, Super Resolution in Computer Vision, Conditional Generation of Molecules in Physics etc.
Time: 2.00 – 3.00 PM (IST)
Speaker: Dr Sanmay Ganguly (University of Tokyo, Japan)
Title: The Deep Relation Between Particle Physics and Machine Learning
Abstract: At the CERN Large Hadron Collider (LHC) experiment, trillions of protons get smashed with each other at very high energies every second. Remnants of this collision are collected and studied to infer what fundamental interactions are happening at the core. Analysing and extracting meaningful physics information out of this large data is a highly challenging statistical analysis, part of which has to be carried out in real-time. Modern deep learning techniques have brought a change in paradigm in the whole field, where it is observed that the application of ML truly impacts at all corners. In this presentation the speaker will try to give a general overview of the ongoing ML activities, mainly highlighting the areas in the context of LHC physics and shortly touch other branches of HEP.
Time: 3.30 – 4.30 PM (IST)
Speaker: Prof Lasse Laurson (Tampere University, Finland)
Title: Machine Learning Plastic Deformation of Crystals
Abstract: The speaker will present an overview of our recent efforts to apply machine learning to predict the fluctuating plastic deformation process of small crystals, mediated by the stress-driven motion of dislocations. To this end, we use machine learning to establish mappings between the initial state of a sample and the corresponding stress-strain curve, considering different loading protocols and geometries of the dislocation assembly. He will start with a discussion of machine learning the depinning process of edge dislocation pileups, after which he will consider the problem of machine learning-based prediction of the stress-strain response of two- dimensional systems of discrete dislocations subject to stress-controlled and strain-controlled loading.

About the talk: Emergence: Modern Physics to Nanoscience to Advanced and Quantum Materials
The beginning of the 20th century has dawned a new era of modern physics with the evolution of a plethora of experimental techniques that include understanding of optical and x-ray spectra, Rutherford scattering, Stern-Gerlach experiment that led to the discovery of electron spin, with simultaneous progress in the fields of superconductivity, magnetism, spintronics, crystallography and the physics of low dimensional systems that in other words is termed as nanoscience which deals with 2D, 1D and 0D systems. We know that matter is made up of atoms, atoms make up crystal lattices, and electronic correlations play an important role in determining the physical properties of materials. I will explain the enormous progress materials science has made and the potential it offers in various technologies. I will talk about the emergence of ‘quantum materials’ and how quantum effects are inherently built-in certain material systems, for example, high-temperature superconductors. I will give examples citing potential applications of functional materials and brief about diamond, the wonder material for futuristic quantum applications.Continue reading →

The discovery of Dirac and Weyl semimetals (WSM) has brought forth the condensed-matter realization of Dirac/Weyl fermions, which were previously theorised as low energy excitations in high energy particle physics. In the recent past, we have witnessed some exceptional developments in chalcogenide and pnictide materials that have been identified with such properties. Several age-old industrial materials based on selenides, tellurides, borides and oxides have come to the fore that promise to usher in a new understanding of correlated electronic systems. Towards material implementation of quantum computation, we shall review the electromagnetic properties of topological superconductor SrxBi2Se3 and study its pairing mechanism. Several transition metal mono-pnictides are under intense investigation for understanding the properties of inversion-symmetry broken Weyl semimetals. Non-trivial Berry phase and chirality are important markers for characterizing topological aspects of Weyl semimetals. We shall discuss aspects of exceptional magneto-resistance seen in the normal state of these topological semimetals. In specific, we shall summarize potential applications with regard to material properties of the following systems a) Single-stage cryocooled superconducting magnets for MRI (MgB2), b) Cables for lossless energy transmission and storage (Bi2Sr2Ca2Cu3O10), c) Materials to implement Quantum Computation (Sr intercalated Bi2Se3), d) Better read-heads for magnetic storage devices (NbP, TaSb2), e) Magnetic Nano-particles for Cancer therapy (Co+CoO EB), f) Thermoelectric materials for waste heat scavenging (ZrNiPb), g) Next-generation piezo devices using multiferroic materials. (Y2CoMnO6) and h) new ideas on solar energy and battery applications.
