LSS Talk

Taking Back What’s Yours: Regaining Ownership of Data

Your data are vital data source for everything from marketing decisions to artificial intelligence. But here’s a simple yet important question: Who actually owns your data?

In this talk, Prof. Dr. Renana Peres (Hebrew University Business School and Visiting Scholar at the University of Luxembourg) explores a future where each of us owns and controls our personal data. This idea goes far beyond privacy protection. Imagine being able to decide:

  • Who can access your data
  • What it can be used for
  • Whether, and how much, you charge for it

Could such a shift transform how businesses, platforms, and consumers interact? Could it reshape the entire data economy?

Drawing on her newest research, Prof. Peres will introduce the three pillars of data ownership — Protection, Control, and Monetization — and invite us to think about what happens when consumers, not intermediaries, sit at the center of the data ecosystem.

📅 When: Wednesday, 17 September 2025, at 18:00 (welcome from 17:30)
📍 Where: Belval Campus, Room MSA 3.160
🥂 Followed by informal drinks

Join us as we kick off the new academic year with this thought-provoking talk and lively exchange of ideas.

First LSS Price winner awarded!

On 31/01/2025, three nominees competed for the first LSS price honoring the best internship report.

Aleksandra Frania, Master in Data Science: Causal inference Methods and Tools(Internship done at Goodyear)

Fatéma Goulamaly, Master in Industrial Mathematics: Predicting the Degradation of Li-ion Battery Using Hybrid Machine Learning and Empirical Methods (Internship done at Siemens Industry Software SAS)

Rym Kaced, Master in Financial Mathematics: Insurance and ALM: Introduction to Strategic Asset Allocation (Internship done at PWC)

While all three did a terrific job and the jury deliberation was a close call, the award goes to Aleksandra Frania for advocating the use of causal inference methods in practice.

Congratulations Aleksandra!

Invitation to Time Series Analysis: Theory &Applications

We are happy to announce that the talk by Professor Masanobu Taniguchi from Waseda University, Japan will take place on Wednesday April 17 at 6.30pm at the University of Luxembourg on the Kirchberg Campus (6, Rue Richard Coudenhove-Kalergi) in the main building, room D10F. The talk will be followed by a drink.

Abstract

This talk delves into the transformative and innovative potential of two cutting-edge technologies – Large Language Models (LLMs) and blockchain – for the field of statistics, and in particular, Official Statistics.

In this talk, topics from the elementary statistics to modern new one will be delivered. First, we explain the meaning of mean, variance, deviation, of statistical data. As the theoretical aspect, we introduce mathematical statistics, mentioning estimator, unbiasedness, sufficiency etc. For goodness of estimator, Rao-Blackwell theorem is stated with an interesting episode of C.R.Rao.

Then we explain the elements of time series, feature of financial data, and nonlinear time series models. Their optimal inference is discussed based on LAN structure, and as an optimal estimator, MLE is given. We apply time series analysis for medical data e.g., ECoG, EMG data to illuminate diseases.

Actual data are essentially non-stationary. For such time series, the optimal inference is established. Classification problems are addressed for such data.

We also deal with the problem of portfolio. For this the optimal portfolio coefficients are given by our modern statistical methods.

As an interesting episode, Nightingale’s life will be mentioned. We explain her relationship to statistics and graphical method in statistics.

Finally, Granger causality will be introduced two time series, and we apply this concept for tourism statistics.

Large Language Models and Blockchain in Statistics: Innovations and Use Cases

The Luxembourg Statistical Society would like to invite you to the talk by Cristiano Tessitore on “Large Language Models and Blockchain in Statistics: Innovations and Use Cases”. The talk will take place on Thursday 7th March at 12:00 PM.

Raul Ian Sosa is from Eurostat

Abstract

This talk delves into the transformative and innovative potential of two cutting-edge technologies – Large Language Models (LLMs) and blockchain – for the field of statistics, and in particular, Official Statistics.
LLMs, with their enormous data processing and natural language understanding capabilities, have gained increasing popularity since the launch of OpenAI’s ChatGPT in November 2022. This development has made the generative AI sector increasingly competitive, with new breakthroughs emerging daily, making LLMs a perfect “teammate” for scientists.
Blockchain technology, thanks to its innovative features like immutability, transparency, and decentralization, can strengthen trust in official statistical results.
By combining LLMs and blockchain, this speech aims at showcasing a future where statistical analysis is more efficient, accurate, and trustworthy. Attendees will gain insights into practical applications and the potential of these technologies to transform the statistical landscape

Understanding the Potentials and Pitfalls of ChatGPT and AI Language Models

The Luxembourg Statistical Society would like to invite you to the talk by Raul Ian Sosa on “Understanding the Potentials and Pitfalls of ChatGPT and AI Language Models”. The talk will take place on Wednesday 13th September at 6:00 PM.

Raul Ian Sosa is doctoral researcher at Department of Physics and Materials Science of University du Luxembourg

Abstract

In recent months, AI language models have skyrocketed in popularity among both companies and end users. ChatGPT, in particular, has become the fastest-growing web platform of all time and serves as a formidable tool for tasks ranging from simple text summarization to complex ones such as writing entire emails and generating pieces of software. In this talk, we will delve into the creation and evolution of this revolutionary technology, demystifying what these AI models are and envisioning the future they might shape. Despite these new solutions offering immense possibilities, they also pose challenges such as the risk of generating misleading information and perpetuating societal biases. We will dissect these issues, understand their roots, and explore strategies that we, as users, can employ to mitigate them, ensuring the responsible use of these sophisticated tools.

Date: 13 September 2023
Time: 18:00-19:00
Place: Metz Room, ground floor of the SnT Building (29, av, JF Kennedy, Luxembourg)
Fee: free

Towards a framework to harness data by citizens: the Istat experience

The Luxembourg Statistical Society would like to invite you to the talk by Monica Pratesi on “Towards a framework to harness data by citizens: the Istat experience”. The talk will take place on Monday 17th April at 12:00 PM in virtual mode.

Monica Pratesi is Director of the Department for Statistical Production, Istat, Italian National Institute of Statistics

Abstract

Big data, smart statistics, digital administrative data, and citizens are inseparable: from smartphones, meters, fridges and cars to internet platforms, the data of most digital technologies is citizen data, that is the data of the citizens and on citizens.

Their importance and their involvement ask for a thorough rethinking of the relations between the citizens and the production of official statistics. In the session we will focus on examples of the reuse of data generated by citizens on themselves (in processes like using services, making telephone calls or when they populate administrative archives during their lives as students, workers, retired persons etc.) to produce Official Statistics. Examples will use the statistical production process from the Permanent Population and Households Census, from the integration process of utility data files (e.g. electricity, gas) in the design of different activities, like for instance the Household Energy Consumption Survey or data collection on violence against women and on discrimination (LGBTQ+ population, Roma and homeless) conducted in cooperation with civil society organizations, also touching upon the issue of the reuse of privately-held-data in official statistics.
