Keynote #1 – Statistics with a human face

Adrian Bowman, University of Glasgow (SCOTLAND)

Read more...

Three-dimensional surface imaging, through laser-scanning or stereo-photogrammetry, provides high-resolution data defining the surface shape of objects.  Human faces are of particular interest and there are many biological and anatomical applications, including assessing the success of facial surgery and investigating the possible developmental origins of some adult conditions.  An initial challenge is to structure the raw images by identifying features of the face.  Ridge and valley curves provide a very good intermediate level at which to approach this, as these provide a good compromise between informative representations of shape and simplicity of structure.  Some of the issues involved in analysing data of this type will be discussed and illustrated.  Modelling issues include simple comparison of groups, the measurement of asymmetry and longitudinal patterns of shape change.  This last topic is relevant at short scale in facial animation, medium scale in individual growth patterns, and very long scale in phylogenetic studies.

Round table: Artificial intelligence and big data in business

Organizer and moderator: Vincenzo Esposito Vinzi, ESSEC Business School

AI at the heart of outstanding customer experiences

 The future is now and it is all about customer experiences.  But what does a beautiful experience look like?  We explore how Artificial Intelligence (AI) is enabling a new era of personalization driven by deep insight and predictive optimization.  We will look at how AI enables organizations to sense, comprehend, act and learn, and review how Accenture has put AI at the heart of its role as Innovation Partner at Carnival Corporation to transform customer experiences.

Jean-Pierre Bokobza: Senior Managing Director – Global Geographic Sales Lead, Accenture Digital
How AI & Big Data technology are changing the customer expectation, offering new ways to offer broader and personalized experiences?

Lots of industries are facing the challenges of digital transformation, customer have more choices and are now caring about experience. We will show, through real use cases, how we can leverage the advances in AI and predictive analytics to create unique offers and experiences at scale, that appeal to the needs and desires of each individual customer.

Data to change: knowledge sharing between research and firms in the statistical analysis of Big data

Technological evolution in the production of data does not always go hand in hand with a cultural evolution, which enables non-specialists to understand and take advantage of innovation. The cultural evolution to understand the key points and meaning of the profiling of the consumption behaviors, reading habits, and attitudes in real time is deeply rooted into statistics and data analysis.

Data and statistical literacy have particular relevance in the activities of companies and firms, when complex analyses are undertaken by teams from diverse backgrounds.

The question on how academics, statistical associations and firms can cooperate to promote and develop statistical literacy to enhance not only change and innovation, but also progress in societies has not yet a clear answer.

Monica Pratesi: SIS President – Full Professor of Statistics, University of Pisa
How are companies using big data today? Some concrete examples.

The private industry is currently putting a lot of efforts to transform their businesses into smart businesses. In fact, the full digitalisation of companies activities’ generates data usable for increasing operational efficiency and for creating new products and services. The characteristics of this data necessitates automated procedure typically using AI. Based on strategic big data analytics case studies from large companies, we give concrete examples of the type of data used, the algorithms and the data valorisation.

Mobile Data for Social Good: How Mobile Operators are Building Sustainable and Responsible Business.

ICTs are an important enabler of economic growth and development. Mobile phones technology is experiencing massive penetration rates globally, even in low and middle-income locations, reaching urban and rural populations, across all socio-economic spectra. Each mobile device generates an incredible amount of information that yields unique insights on human behaviour, particularly relevant and promising for the social sector. In 2015, United Nations have called for a ‘data revolution’, as an enabler of evidence-based policies and programs to reach the most vulnerable. Mobile operators are working closely with public agencies and NGOs to establish a common framework and ecosystem that can help provide that information, to eventually improve the lives of billions of people and the environment in which they live. Orange has also supported this cause, launching several initiatives and studies that have shown the value of engaging through and about data.

Keynote #2 – Statistical challenges in the analysis of complex responses in biomedicine

Sylvia Richardson, University of Cambridge (UK)

Read more...
To exploit better the structure of the rich sets of characteristics, such as clinical biomarkers, molecular profiles or detailed ontology records, that are currently being collected on large samples of healthy or diseased individuals, statistical models of the variations within and the interplay between different layers of data can be constructed. Generic Bayesian model building strategies and algorithms have been tailored for this purpose. In this talk, I will discuss three areas: implementing joint hierarchical modelling of a large number of responses and a large number of features to discover features associated with many responses ; analysing tree structured ontology data with application for finding the underlying genetic origin of rare diseases; and characterising network structures using fast Bayesian inference in large Gaussian graphical models. Common statistical issues of accounting for model uncertainty, ability to borrow information for retaining power and scalability of Bayesian computations will be highlighted. Modelling strategies and computations will be illustrated on case studies.

Keynote #3 – Unifying Data Units and Models in (Co-)Clustering

Christophe Biernacki, Université Lille 1 (FRANCE)

Read more...
Statisticians are already aware that any modelling process issue (exploration, prediction) is wholly data unit dependent, to the extend that it should be impossible to provide a statistical outcome without specifying the couple (unit,model). In this talk, this general principle is formalized with a particular focus in model-based clustering and co-clustering in the case of possibly mixed data types (continuous and/or categorical and/or counting features), being also the opportunity to revisit what the related data units are. Such a formalization allows to raise three important spots: (i) the couple (unit,model) is not identifiable so that different interpretations unit/model of the same whole modelling process are always possible; (ii) combining different “classical” units with different “classical” models should be an interesting opportunity for a cheap, wide and meaningful enlarging of the whole modelling process family designed by the couple (unit,model); (iii) if necessary, this couple, up to the non identifiability property, could be selected by any traditional model selection criterion. Some experiments on real data sets illustrate in detail practical beneficits from the previous three spots. It is a joint work with Alexandre Lourme (University of Bordeaux).

Keynote #4 – Bayesian Model-Based Clustering with Flexible and Sparse Priors

Bettina Gruen, Johannes Kepler Universitat Linz (AUSTRIA)

Read more...
Finite mixtures are a standard tool for clustering observations. However,
selecting the suitable number of clusters, identifying cluster-relevant
variables as well as accounting for non-normal shapes of the clusters are
still challenging issues in applications. Within a Bayesian framework we
indicate how suitable prior choices can help to solve these issues. We
achieve this considering mainly prior distributions that have the
characteristics that they are conditionally conjugate or can be
reformulated as hierarchical priors, thus allowing for simple estimation
using MCMC methods with data augmentation.

Keynote #5 – Grinding massive information into feasible statistics: current challenges and opportunities for data scientists

Francesco Mola, Università di Cagliari (ITALY)

Read more...

Massive amounts of data used to make quicker, better and more intelligent decisions to create business value are nowadays available for companies and organizations. Terms like big data, data science, analytics, artificial intelligence, machine learning etc., are very common in both academia and industry. All these areas of research are orientated towards answering the increasing demand for understanding trends and/or discovering patterns in data. Usually, collected data is massive and uncertain due to noise, incompleteness and inconsistency. The main goal of a statistician/data scientist is therefore to turn massive data into feasible information, the latter intended as able to describe efficiently an observed phenomenon, to gain indications about its future evolution as well as to provide useful insights for the ongoing decisional process. All these considerations lead towards arguing that the role of the statistician/data scientist considerably evolved in the latest years.

In my presentation, after a brief description of the scenario summarized above, I will discuss three examples/case studies concerning image validation, hotels’ reputation and social media popularity trying to give a contribution to the debate about turning the enormous amount of available data into feasible statistics. In all cases, ad-hoc but standard classification methods are used to obtain information that is extremely feasible and adds value to a decisional process.
