About The Conference

What is DataMass?
It’s not just another conference. It’s an event created with passion – and targeted at those who use Big Data in practice in their everyday work. The main idea behind the conference is to promote knowledge and experience in designing and implementing tools for the analysis of big data volumes.

We connect the people who care
We believe that building a community of dedicated experts will help us share knowledge and exchange experience in shaping scalable and distributed computing solutions.
We value real-life expertise – is there any better way to learn than from actual specialists? Our speakers, true practitioners from top data-driven companies, will show you what they have learned and discovered about the Big Data world.

Answering your needs
Playing an active role in the Big Data world, we could see that a big technical conference focused on the exchange of knowledge and experience in this field was needed in Poland. The aim of DataMass is to create a synergy between businesses focused on the creation and implementation of Enterprise-class solutions, together with experience and knowledge of the academic environment. The Data Science meetup in Gdańsk is a tangible proof that this is currently possible.

      9:20 - 9:50
      Piers Campell
      This presentation examines the phenomenon that is data science. Lauded as the “sexiest job of the 21st century”, it grew out of humble and pretty un-sexy beginnings to become the must have CV line item. How did it get to where it is today? Can anyone do it? Where might it be going next? And the question I’m asked most frequently, is it really a science? I will attempt to answer all of these questions, along with exploring, how the evolution from big to smart data and might affect the future of data science for practitioners and the wider data community.

    • Pragmatic Machine Learning for Business

      14:30 - 15:00
      Jakub Nowacki
      Currently machine learning and artificial intelligence get a lot of attention, especially from business, for which these concepts are quite new. Often when you go through all the examples available online, it comes out that all the general models distinguishing cats from dogs are not quite suitable for your particular business. Moreover, very little is said about how to obtain data in the first place, as most of the examples use available data sets, which are clean and well prepared for the task; quite opposite to what you usually have in real business. In this talk I will take you through a classification example, which adopts existing model using transfer learning to a specific business case, including data set creation. Then we will harness the power of the distributed computing to train the model and deploy it to production in accordance to the serverless paradigm. The presentation proposes example solutions, which can be transferred into different systems.

    • Engineering Methods to Improve the Performance of Data Science Models

      11:20 - 12:00
      Grzegorz Gawron
      In situations where 1% optimisation improvement might be worth millions – algorithm tuning, parallelisation etc – might turn out to be just the things that count. Grzegorz Gawron walks you through some cases where software engineering (computer science?) goes hand in hand with data science. All based on VirtusLab's real-world projects.
    • Data ethics: from compliance to data trust

      12:00 - 12:45
      Bill Wilson
      Conferences like Datamass are exciting because every year there are new opportunities to exploit data and new technologies to do that more effectively. However, as highlighted by recent high-profile news stories in the area of data privacy, those exploitation opportunities may immediately run into some ethical challenges. We already have some privacy regulation, and no doubt more is on the way but data ethics goes beyond compliance. Could trust be a differentiator for your business? How can governments maintain data trust with citizens? This session will look at what can go wrong and some steps we might take if we want to lead on data trust. As data professionals who understand the power of the tools in our hands, I believe we need to lead on how to use them responsibly. This is not a technical presentation (you won’t see any demos), but is particularly relevant for those doing data science with data sets that contain personal data or where individuals can be re-identified. A general audience will also appreciate this session – after all we’re all data subjects…

    • Facilitating ambient intelligence with distributed ledgers: a case study in smart energy

      14:30 -15:00
      Stanisław Raczyński
      We have witnessed 3 disruptive technological milestones in distributed ledger technologies (DLTs) thus far: 1. digital assets (e.g., Bitcoin), 2. Turing abstraction (e.g., Ethereum), and 3. IoTization (e.g., IOTA). With these, we are on our way to a next level of big data, as blockchain is nothing more than a immutable, consensus-based distributed database with a strict set of operations we can perform on it, and now we are enabling millions of devices to participate in this large-scale data collection and sharing. Imagine for example the impact of a billion connected and publicly available weather sensors around the globe to the area of data-driven weather prediction! In this talk I will paint a vision of how IOTA will be employed to facilitate ambient intelligence of distributed energy resources (DER) in the free market of data and energy. I will tell you how your EV, your EV charger, your photovoltaics and your home energy storage will communicate, learn from a global decentralized database and make autonomous cost-optimizing decisions and suggestions, all atop IOTA.
    • The Hassle with Monads

      15:00 - 15:30
      Maciej Godek
      Monads are a concept from functional programming that tends to confuse most newcomers. Having studied them for five years, Maciej is hoping to warn his audience about some common pitfalls that one can run into when trying to comprehend them.
    • Predicting speedway results using online update algorithms

      15:40 - 16:10
      Dawid Kałędkowski
      Sport or computer games rivalries need up-to-date estimation of players strength to suggest relevant opponent, specify risk or value bets. Online updating algorithms perform very well when data flows are continuous or sudden, saving computation capacity and processing time. Examining performance of speedway riders, several methods will be presented, explained and applied using R. You will learn also who was the best speedway rider last year, who is at the top now, and how riders abilities changes in time.






Datamass 2017


  • While many technical conferences present the theory of whatever technology they cover, it was great to see that both the organizers and the speakers of DataMass paid attention to the practical part above all. Theory is one thing, but the implementation of it is a whole new experience – and it’s great to have an event that gives big data professionals space to present their work.

    Lukasz Grala

    TidK, MVP Microsoft
  • It’s amazing to see that Big Data is becoming more and more popular as numerous meetups and conferences spring up all across Europe. Gdańsk needed an event like that, and I believe that DataMass is a great occasion for those who use big data to meet other experts and enthusiasts and chat about their experiences and lessons learned.

    Balazs Ferenc Gaspar

  • Being a speaker at the first-ever DataMass Summit was a fantastic experience. Not only was it an occasion to exchange knowledge with other professionals from the field, but also a great opportunity to see how the community of big data enthusiasts is growing and developing. Combining great fun with practical knowledge is the key to a successful event of this type – and the organizers managed to do it.

    Jakub Nowacki, PhD

  • DataMass Summit 2017 was the first edition of the conference and definitely not just another conference of this kind. How was it different? First of all – the venue. It took place in a post-industrial shipyard building. Not a very typical place to hold a technical conference, but it worked! Secondly, the conference was purely practical. Speakers focused on their experience, and not just the theoretical part, which in turn gives a lot of space for others to learn.
