Introduction by MARCO MELLIA, coordinator of the SmartData@PoliTO center
After 1 year since the SmartData@PoliTO started, we are now more then 50 people, working on both fundamentals and applications of Big Data, Machine Learning and Data Science. We have started several collaborations with companies, designed a new data center, organised a physical space, participated into projects. What’s next?

Marco Aldinucci (UNITO) – The evolution of high-performance systems: from HPC to Big Data to Deep Learning
Computer science evolves through successive abstractions. Today, after 30 years of lethargy, high-performance computing (HPC) is extending beyond its traditional fields of application. For years HPC systems have been feeding with differential equations; the ability to calculate many mathematical operations per second (FLOPS) was the key to solving ever larger problems and to find ever more precise solutions. The explosion of data resulting from digital transformation has shifted the demand for high performance from traditional applications (equations, simulations, etc.) to methods for the analysis of large amounts of data (BigData, Deep Learning, etc). Under this impulse, the programming and use models of HPC systems are evolving towards much more abstract models, able to satisfy different application needs and to simplify the development of new applications. The challenges for designers are renewed: from FLOPS to the efficient management of data in memory; from mathematics in double precision to that in small but efficient precision for deep neural networks. A blow of life for high-performance systems researchers: experimenting with new workloads, platforms, programming models, provisioning models. To meet these challenges, the University of Turin and Polytechnic University of Turin have joined forces to create a federated competence centre on High-Performance Computing (HPC), Artificial Intelligence (AI) and Big Data Analytics (BDA). A centre capable to collaborate with entrepreneurs to boost their ability to innovate on data-driven technologies and applications.
Marco Aldinucci is an associate professor at Computer Science Department of the University of Torino (UNITO) since 2014. Previously, he has been postdoc at University of Pisa, researcher at Italian National Research Agency (ISTI-CNR), and University of Torino.

Antonio Vetrò (NEXA & FULL) – Fairness in automated decisions: motivations and preliminary researches
Automated decision systems and recommenders (e.g., ranging from automated resume screening to credit score systems to criminal justice support systems) are profoundly changing our lives, substituting experts in an increasing number of decisions and fields. They influence our vision of the world and mediate our interactions with it. In such a context, an increasing number of scientific studies and journalistic investigations has shown that such automated decision systems may have discriminating behavior and amplify inequalities in society: systems that are “evidence-based” or “data-driven” by no means ensure that they will lead to accurate, reliable, or fair decisions. In such a context, scientific communities are devoting considerable effort in understanding whether it is possible to achieve fairness in these systems, and how to measure it. In this talk we will have an overview of the problem and we present preliminary research approaches and results.
Antonio Vetrò is post-doctoral research fellow at the Nexa Center for Internet & Society and at the Future Urban Legacy Lab at Politecnico di Torino. He is also member of the UNI Technical Commission on Software Enginering. Currently, Antonio is conducting research on how to detect and mitigate potential discriminations deriving from biases in the data and in the algorithms of decision systems. Antonio is specialized in empirical methodologies and statistical analyses, applying such an empirical epistemological approach to study the impact of technology on society.
Second Session: 16:20 – 18:00
Carlo Baldassi (Bocconi) – Julia: a programming language for data science
Julia is a young programming language particularly well-suited to technical computing. Its main strengths rely in being a very high-level language, comparable to Python or Matlab for example, with performances on par with low-level languages like C or Fortran. It is thereby very apt to all sorts of “number-crunching” applications. Moreover, the general philosophy of the language (and in particular its sophisticated type system) is geared towards allowing to obtain excellent performance from very generic and reusable code, which greatly helps the inter-compatibility of disparate software packages and user-code. I will discuss these basic aspects of the language and in particular how it proves effective in data science applications, with examples.
Carlo Baldassi is an Assistant Professor at the Department of Decision Sciences at Bocconi University, Milan, where he teaches Computer Science courses. His background is in Theoretical Physics, computational biology and computational neuroscience, and his current research activities focus on the study of non-convex optimization and inference problems and the properties of state-of-the-art machine learning schemes. He is an early adopter of Julia and has been a very active early contributor in the initial phases of the development of the language, and has written and maintains several Julia packages.
Riccardo Loti (Tierra Telematics) – Operating and evolving a distributed IoT platform
Tierra Telematics provides telematics services to Original Equipment Manufacturing (OEM) and After Market (AM) customers.
We describe how a telematics solution is designed, built, and deployed, starting from the ground up (hardware design, cost analysis, firmware development), to the software layers (database, cloud architecture, application layers) to the data analytics (business intelligence, data exploration). We also describe the growing need for intelligent data analytics, and the challenges involved.
Riccardo Loti is the head of Applied Research in Tierra S.p.A.. Coming from an academic background, he got a PhD in Computer Science in 2014 from the Università degli Studi di Torino and the Universiteé de Nice-Sophia Antipolis. He got a background in Networking and Artificial Intelligence, an experience working abroad and in different fields, and a curiosity in everything interesting.
Tania Cerquitelli (POLITO) – Visualizing high-resolution exploratory energy maps by analyzing energy-performance certificates
In the talk I will present the current research project with EDISON SpA on the topic “City building mapping: using public data to find energy efficiency of buildings”, that focuses on the harvesting of open data for the characterization of the energy efficiency and consumption of residential buildings. We are mainly focusing on extracting actionable and human-readable knowledge items from a real and open collection of Energy Performance Certificates (EPCs), providing interesting information on the energy performance, thermo-physical and geometrical properties of buildings in the city of Turin. A two-level data analytics methodology based on exploratory algorithms and knowledge visualization has been designed. Specifically, an unsupervised algorithm divides EPCs into homogeneous groups of buildings with similar thermo-physical characteristics. Each group is locally characterized through interesting patterns. Then, extracted knowledge items are visualized and can be navigated on high-resolution geo-located maps to summarize the main relationships among variables affecting the energy efficiency of buildings at different spatial granularity levels. These high-resolution energy maps allow different stakeholders to quickly identify potential sites and start assessing their energy efficiency. Differently from the state-of-the-art algorithms, the proposed methodology visualizes high-resolution energy maps empowered by the clustering step which (a) jointly considers (in each cluster) the effect of multiple variables affecting the energy efficiency of buildings, (b) graphically presents the information by means of powerful abstractions, and (c) provides a zooming capability to explore data both at coarse and high-detailed levels.
Tania Cerquitelli has been an Associate Professor at the Department of Control and Computer Engineering (DAUIN) of the Politecnico di Torino, Italy, since March 2018. Her research interests include self-learning methodologies, transparent data anaytics algorithms providing human readable data models, the design of innovative algorithms to perform large-scale data mining, novel and efficient data mining techniques for sensor readings, algorithms to extract high-level abstractions of the mined knowledge (e.g., generalized patterns).

Marco Fiore (CNR) – Urban Vibes and Rural Charms: Analysis of Geographic Diversity in Mobile Service Usage at National Scale
We investigate spatial patterns in mobile service consumption that emerge at national scale. Our investigation focuses on a representative case study, i.e., France, where we find that: (i) the demand for popular mobile services is fairly uniform across the whole country, and only a reduced set of peculiar services (mainly operating system updates and long-lived video streaming) yields geographic diversity; (ii) even for such distinguishing services, the spatial heterogeneity of demands is limited, and a small set of consumption behaviors is sufficient to characterize most of the mobile service usage across the country; (iii) the spatial distribution of these behaviors correlates well with the urbanization level, ultimately suggesting that the adoption of geographically-diverse mobile applications is linked to a dichotomy of cities and rural areas. We derive our results through the analysis of substantial measurement data collected by a major mobile network operator, leveraging an approach rooted in information theory that can be readily applied to other scenarios.
