• Knowledgefeed: Efficient ML for mobile devices & Segmentation in Surveys

    Dear Community, We hope you had a great summer! We are very happy to announce that the VDSG is back from summer break, too, and our next meetup is happening in two weeks in A1! This time we are having two talks: Segmentation in surveys and efficient machine learning for mobile devices. Jelena Milosevic: "Efficient machine learning for mobile devices" (30-35 mins) Increased amount of data allows for better training and more accurate machine learning systems. Big part of generated data today is coming from embedded and mobile devices, whose number is constantly on the rise. In order to fully profit from the collected information, artificial intelligence should come to these devices. However, this is currently difficult to achieve, mostly due to the computational demands of machine learning systems being too high for constrained computational resources of mobile devices. One of the reasons for this is that, when designing machine learning methods, most people only focus on accuracy, without taking into account constrained computational resources of developed solutions. Many applications rely on efficient machine learning. Some examples are: vision and image processing, autonomous driving, and malware detection. In order to facilitate novel applications in these domains, it is of utmost importance to provide machine learning solutions that are not just accurate, but also suitable for constrained environments. In my talk I will discuss how we can design and develop such solutions suitable to be used in real-time, on-device, and at the same time customizable with respect to application requirements (accuracy, inference time, and power consumption). Jelena Milosevic is passionate about machine learning and cybersecurity. She is currently a postdoctoral researcher at the Institute of Telecommunications, TU Wien, where she designs and develops machine-learning-based methods for detection of cyber attacks. She obtained her PhD in 2017 from Faculty of Informatics, University of Lugano, Switzerland, where her main focus was on the malware detection systems suitable for runtime usage on resource constrained systems and based on machine learning methods of low complexity. Previously, Jelena was an intern at IBM Cyber Security Center of Excellence in Beer Sheva, Israel, where she worked on the time-series analysis for anomaly detection and in Movidius an Intel Company in Dublin, Ireland, where she worked on the design and development of deep learning methods suitable for embedded environments. https://www.linkedin.com/in/milosevicjelena/ Marcin Kosiński: "Segmentation in Surveys using NMF" (30-35mins) Working with high dimensional data? Often facing the need to group observations? This presentation is for you. Segmentation should be balanced and distinctive, the discovered over- and under-indexed features within segments should create a meaningful story, and, ideally, the amount of differentiative factors that drives segmentation should be small. The last requirement often becomes a bottleneck in a survey where respondents are asked an enormous amount of questions. One solution is the nonnegative matrix factorization that, in one attempt, segments respondents and their features! The concept of the NMF decomposition and applications in R will be presented with the explanation of diagnostic plots. Marcin has a master degree in Mathematical Statistics and Data Analysis specialty. Challenges seeker and devoted R language enthusiast. In the past, keen on the field of large-scale online learning and various approaches to personalized news article recommendation. Community events host: organizer of Why R? conferences whyr.pl. Interested in R packages development and survival analysis models. Currently explores and improves methods for quantitative marketing analyses and global surveys at Gradient Metrics. https://www.linkedin.com/in/marcin-kosi%C5%84ski-81435aab/

  • Big data-Industrial IoT Meet-Up Linz

    Hotel Kolping

    Dear Community, Everyone is talking about Big-Data and its increasing importance. You are interested in this topic and want to learn more about integrating such solutions into your business? You want to listen to experts and think that afternoon coffee is the best time to discuss? Vienna Data Science Group is pleased to invite you to the first Meet-Up presented together with the Uni software plus GmbHin Linz. Agenda: Talks: "The Evolution of Machine Data Pipelines at ENGEL" by Christoph Schönegger (ENGEL AUSTRIA GmbH), Stefan Janecek (uni software plus GmbH) "Building 1st Data Science Community in Slovakia" by Radovan Kavicky (Vienna Data Science Group) Afterwards: Discussion with drinks & snacks Registration: [masked] (open until[masked]) The Meet-Up will be in English language. Further Information "The Evolution of Machine Data Pipelines at ENGEL": According to Forbes [1], 90 percent of the data humanity owns today has been generated in the past two years. One of the main drivers behind this breath-taking world-wide data growth is industrial IoT (IIoT), the extension of the "internet of things" (IoT) to the industrial sector. In their talk, Christoph Schönegger (Engel Austria) and Stefan Janecek (uni software plus) will share their story of developing the "Engel Edge Device", a secure solution for collecting, cleaning, aggregating and processing IIoT data "on the edge", i.e., close to the source of the data. The Edge Device System allows to centrally manage containerized applications, and deploy them to small hardware appliances running "on the edge". These applications range from simple ETL (extract transform load) processes to algorithms that make decisions based on data and feed those decisions back into production machines. Since security is paramount in industrial applications, the Edge Devices are protected by strong cryptography, using the on-board TPM 2.0 chip as a trust anchor. In addition to the security considerations on the Edge Device itself, the talk will also describe the secure data logistics solution to transfer data from the Edge Devices to a central Hadoop data lake. https://www.forbes.com/sites/bernardmarr/2018/05/21/how-much-data-do-we-create-every-day-the-mind-blowing-stats-everyone-should-read/#18f7e27660ba We are looking forward to welcome you to an informative evening!

First Big Data project was on account-tickets in a book keeping service (low tech approach). Where the most see just numbers and letters, he finds a purpose and information. For a while now he is playing on a field of DM/ML models for business purposes, with the last couple of years having a spotlight on text analytics and NLP (unstructured datasets) This talk is going to be about how we develop models which can tell us with high accuracy rate if the debt user will go into the personal bankruptcy. Our algorithms are self-learned, so with every new iteration result are showing greater accuracy. In the first part of the talk we shall speak about how we used Gradient Boosting Machines (GBM) & Random Forest on the past and current data of credit debts of the users (such as how much are the user in the minus on bank and credit cards, how long they were late with payments and cetera) to predict personal bankruptcy. We have followed short term loans (up to 60 months), which were granted in the US. Project was also done for several Europeans countries, but with a bit lesser accuracy - caused by harder access to the data on customer placements and the level of indebtedness.

  • Knowledgefeed vol. 28: (Big) Data (Science) for Security

    Lassallestraße 9

    Dear Community, Get ready for our 28th Knowledgefeed featuring security research question that motivated an ambitious data collection and analysis approach. While a common opinion is that a collection of "big data" only leads to security and privacy problems - and it often does - however the analysis of large amounts of IT systems behavioral data also enables new experimental approaches to improve IT security and protect us from the cesspool of malware that the internet is. The TARGET research project at St.Pölten UAS started with an initial IT security research question that motivated an ambitious data collection and analysis approach, and that then spawned subsequent challenges in data collection, encoding, storage, processing, experimental algorithm implementation, up to production deployment. This talk reflects on the challenges encountered and experiences made. Talk (duration 45- 60 mins) By Martin Pirker who is a Senior Researcher at the Institute of IT Security Research, St. Pölten University of Applied Sciences. His current work focus is the Josef Ressel Center for Unified Threat Intelligence on Targeted Attacks (TARGET), and all kinds of weird problems that arise when IT (security) meets privacy and big data.
