Which are the most popular hashtags on LinkedIn?
Hashtags on LinkedIn are probably one of the most popular topics about this social network. So naturally, there are assumptions about how LinkedIn’s algorithm uses hashtags. However, I have shown statistically here that hashtags do not significantly impact the virality of posts. Anyway, the dataset I have at my disposal (4.6 million posts) provides an exciting overview of the most used hashtags globally and the differences that exist depending on the language. This analysis is, therefore, fundamentally different from anything else...

The right to failure doesn’t exist with artificial intelligence. This is terrible.
Artificial intelligence, algorithms based on machine learning, have turned our lives into one of efficiency where failure doesn’t exist anymore. For algorithms an error doesn’t exist ; it’s just a prediction that hasn’t worked because of missing data points. This statistical “accident” will be taken into account to improve predictions a step further. In the field of algorithmic governance failure is not an option anymore. This is very dangerous. Actually I think it’s one of the...

Insurances : towards the end of the risk sharing principle ?
There is one very important underlying principle of any insurance : risk sharing. Good drivers cover a part of the risk of bad drivers; people in good health pay for those who fall ill. Americans call this a “socialist” way of doing business. But until now insurances in Europe have always favored a group approach vs. an individualistic one. The data revolution may be the end of this. Here’s why. Customer data will enable user-centric approach...

How would you feel, as a service employee, if you’d have to apologize and accept...
