• Tezos was created first and foremost to address a governance issue in decentralized cryptographic ledgers. It does so by allowing stakeholders to approve updates to the protocol, including the consensus algorithm, and the governance rule themselves. Tezos is written in OCaml (a functional programming language) and rely on Coq for advanced proof checking and formal verification. Source code will be opened and available later this year.

    Arthur Breitman of "Tezos" gave this presentation on this new technology on Wednesday, August 31st at Monetas HQ (Zug – Switzerland)

  • Introduction

    This talk will be about why complete Decentralization and Immutability matter for public block chains, and why it is impossible to have one without the other. This will be used as the basis to discuss the consequences of the recent Ethereum Hard Fork, and what it could mean for the viability and integrity of the platform and its dapp developers.

  • About the Speakers

    Florian Glatz is a lawyer, researcher and software developer with a passion for Blockchain Technology. His legal background lies in intellectual property, competition and data protection law. As a researcher he has worked for the Max Planck Institute for Innovation and Competition, the European University Institute and CNRS. Florian Glatz is also a web developer with over a decade of work experience. Now, he is focused on understanding and embedding blockchain technology in today's information society.

    The Topic:

    Distributed Ledger Technology aka Blockchain is gaining recognition in both private and public sectors. The peer-to-peer technology promises to disintermediate, streamline and standardize processes across a wide range of industries and public service offerings. Although a key innovation of Blockchain Technology is the sophisticated level of self-governance it enables, the technology needs to be recognized by national and international laws and regulations to go from fringe to mainstream. At the same time, Blockchain-based applications and services need to incorporate an understanding of relevant legal norms into their codified rulesets.

    How can we combine the empowering properties of distributed ledgers with the legal tools and frameworks our society has evolved?

    Let's hear it from the view of a Lawyer.

  • Audio Signals Quality Diagnostics with Image Analysis. 
    by Vasily Tolkachev, ZHAW

    In this technical talk I present a number of interesting findings from a project with our industrial partner. The goal was to build a decent discriminative model which is able to distinguish between working and broken sound emitters based on the sound files produced by them. 
    We approached the problem with various image analysis tools by applying different classifiers on spectrograms of these files. A technique called t-SNE, which led to the key findings in the project, is going to be introduced. Having faced a number of data artefacts such as erroneous labels and class imbalance, sufficiently good performance was already achieved with Random Forest after a number of important transformations. In conclusion, a comparison to variational autoencoders will be exemplified.

    Audio Based Bird Species Identification Using Deep Learning Techniques 
    by Elias Sprengel, ETHZ

    Accurate bird species identification is essential for biodiversity conservation and acts as an important tool in understanding the impact of cities and commercial areas on ecosystems. Therefore, many attempts have been made to identify bird species automatically. These attempts usually rely on audio recordings because images of birds are harder to obtain. They work well when the number of bird species is low and the recordings contain little background noise, but they quickly deteriorate when employed in any real world scenario.

    In this talk, we present a new audio classification approach based on recent advances in the domain of deep learning. With novel pre-processing and data augmentation methods, we train a neural network on the biggest publicly available dataset. This dataset contains crowd-sourced recordings of 999 bird species, providing an excellent way of evaluating our system in a more realistic scenario. Our convolutional neural network is able to surpass current state of the art results and won this year’s international BirdCLEF 2016 Recognition Challenge.
