TUTORIAL #1: QUANTIFICATION OF DIFFERENTIAL INFORMATION
ABSTRACT: First, I will introduce the basic concepts from Linear Algebra, which are useful to appreciate the work. In particular the concepts of inner product spaces, linear transformation of these spaces, the change of basis result, the riesz representation theorem finally culminating in the definition of adjoint of an operator. Once this background is at our disposal, I will review the concept of Karhunen Loeve Transform (KLT) for a finite dimensional case. Then we will carry this idea forward to see how KLT can be obtained if we have more than one class. While deriving we observe that a matrix pencil framework naturally arises when we try to represent differential information of one class over the other. A mathematical formulation emerges which can be used for quantification of differential information. Finally we also provide classification results in various scenarios.

TUTORIAL #2: BLOCKCHAIN TECHNOLOGY
ABSTRACT: Blockchain technology has potential as a catalyst for change in the world of business – and much more broadly, our world. The idea of a new software system that powers a consensus-driven form of shared record keeping – enabling the digital transfer of value in a decentralized manner has already had a profound effect, encouraging rapid and substantial investment in what is now commonly referred to as blockchain technology. The ‘distributed consensus’ problem is the question of how multiple, independently run computers can reliably agree on a set of common data in the presence of faults. This technology reduces the ingrained ‘cost of trust’ that currently adds friction to commerce. Blockchain has a host of new potential uses: for cross-border payments, in clearing and settlement for financial transactions, for supply-chain management, for device-to- device transactions in the Internet of Things, to create more reliable property and asset registries, to forge portable digital identities, and to improve record-sharing in sensitive areas such as health care. This tutorial is for students, faculty or industry experts who wish to explore blockchain technology for its potential use to change the world of business or to improve the blockchain technology itself. The tutorial will begin with a review of the fundamentals of blockchain technology, distributed ledgers, and smart contracts. It will then explore the cryptography techniques that not only make blockchain technology possible but also address privacy issues. The demonstration session includes 1. Demo of Blockchain Components- Public key and Private key cryptography, Digital Signature, Hashing techniques, Block Structure, Chaining of Blocks, Forking and Consensus. 2. Voting application implementation on Smart contract Ethereum.
