How to achieve better marketing and market research with Big Data

Technological progress today allows us to enjoy excellent living conditions. Control of space, control of reproduction, control of information are challenges that we have already accomplished. However, time control remains out of reach. Many human obsessions revolve around the power of this resource, offered to us at birth in a desperately finite quantity: time. Staying young, living old, perpetuating your memory, predicting the...

How to get Internet users to share more personal data?

What personal data are Internet users willing to share in exchange for better personalisation of the marketing offer? How to adapt your marketing strategy to get more data? This question is the subject of much debate at a time of the GDPR and the dawn of the entry into force of e-privacy.

Artificial intelligence: a new opponent of reference in the gaming world

Artificial intelligence, algorithms, are now an integral part of our daily lives. They play a role in various fields, which do not always have an obvious link with IT. Indeed, artificial intelligence (AI) is applied in many areas such as robotics, but also games, music, art, health, and many other domains. This article launches our brand-new series on the multiple facets of artificial intelligence by detailing its integration into our...

We need to rethink how to study filter bubbles: here’s why

At the RecSys conference, the last part of my keynote was dedicated to nuancing the myth of filter bubbles and to show the limitations of current academic research and propose a new research framework. Research on filter bubbles has been technology-driven As I explained in my talk, research on filter bubbles has been mainly technology-driven and deterministic. Escaping the “bubble” has been assessed on the basis of clics...

RecSys 2018: where the future of recommendation systems is discussed

What’s the future of recommendation algorithms? If this is a question you have been asking yourself, you may well need to attend the RecSys conference which this year is taking place in Vancouver, Canada. This is already the 12th edition of this conference which is part of the ACM series of conferences on recommender systems. Last year I served in the reviewing committee of the FATRec workshop, a part of the conference which is...

Marketing research: the influence of privacy perception on customer loyalty

What does privacy mean in the age of robots, articifial intelligence and omnipresent algorithms? How do users percive privacy and how is it traded off against other benefits (personalization for instance)? Those are still emerging questions that a team of marketing researchers from the University of Toulouse (France) tried to answer at the 2018 EMAC conference that was helf in Glasgow. More specifically the study looked at the factors...

filter bubbles: scientific evidence that algorithms aren’t to be blamed

What can you discover about filter bubbles when you analyse datasets with billions of tweets over a 8-year period ? Some very interesting results for sure.  In particular that you don’t need algorithms to stay within an echo chamber and that bridging echo chambers comes at a price. This contributes to the ongoing discussion on the very existence of algorithmic filter bubbles. Introduction Garimella et al. (2018) studied...

Data Innovation Summit 2018 : ethics and data sovereignty

It has now become a tradition for me to give some time back to the data science community in the form of a keynote at the yearly Data Innovation Summit organized by Philippe Van Impe. Let’s first allow me to thank Philippe and the team of Digityser for their amazing work for Belgium’s data science community. I was very proud to organize the first meetup at newly opened Digityser (on ethic and artificial intelligence) and...

The Big Data revolution started 2 centuries ago

In her latest article Antoinette Rouvroy develops an interesting thesis The current Big Data revolution would be the continuation of earlier shifts. Let’s see in more details. Numbers and statistics increasingly being used since 19th century Big Data is based on the massive collection of data and would be, according to Rouvroy, an extension of earlier shifts that started with the increasing use of numbers in the eighteenth...

Face recognition algorithms are biases towards black people and women

Joy Buolamwini, a MIT PhD candidate, presented her research at the inaugural FAT Conference in New-York. She had previously given a TED talk and been invited to the White House to present her work on algorithmic fairness. In the paper she presented at the FAT conference Joy showed how face recognition algorithms can be biased towards certain segment of the population and in fact lead to discrimination.   Here are the 2 main...

Artificial intelligence won’t replace you if you are creative: here’s why

“Artificial intelligence will replace us”; “millions of jobs are threatened by artificial intelligence”. I’m sure you all have read those catastrophist headlines. And it’s probably true that the job market will be disrupted on the long run. But I don’t think it’s likely to happen overnight. Most importantly I think some parts of the job market will be entirely safe; those jobs for which...

Dynamic pricing in retail : can smart shelves lead to discrimination?

We presented in another article a great innovation presented at the NRF2018 retail show this year : smart shelves. Those smart shelves are especially interesting because of their built-in cameras to detect customers’ faces and interact accordingly with them. As the website of AWM explains, the embarked face recognition algorithms are able to detect demographic criteria like gender, ethnicity and age (see picture below, source :...

Give me my time back ! I’m a digital slave.

It happens again and again and there is nothing I can do. The temptation is too big. I can’t resist staring at my screen and losing my time watching and doing things that I don’t really want to do. Rather than doing things that would enrich me, I can’t resist the temptation of browsing my Facebook feed, looking at the latest notifications, watching poor videos on YouTube. Social medias are my grave. I want to get out...

Recommendation algorithms : how CNN.com and Quartz learn to better know you

Making meaningful algorithmic recommendations require that your algorithm is “fed” with data about your customers tastes. This can be done in many ways : implicit feedback : it’s when you track a user’s actions and infere her taste based on them collaborative filtering : using someone’s profile and other similar persons’ taste you are then able to make recommendations explicit feedback : when you...

Workshop on fairness and ethics in recommendation systems

On the last day of the RecSys 2017 conference I was fortunate enough to be in the organizing committee of the workshop on fairness, accountability and transparency in recommendation systems (F.A.T.REC). This workshop was the first of its kind within the RecSys community ; the conference is indeed usually very much tech-oriented and Joe Konstan, who chaired the very first ACM Recsys conference, indicated in a plenary session that he...
