The development of new technologies, in particular Artificial Intelligence (AI), used in finance, has strongly accelerated over the last three years and is entering a new phase. The stated objective is to achieve increased human intelligence with the help of digital technology, in particular through deep learning and the emergence of meaningful data.

To illustrate this subject, the new edition of the Cahiers Louis Bachelier deals with the digital transition in finance. The last two articles in this issue, based on the research works of David Bounie and Winston Maxwell of the Digital Finance Chair, affiliated with Télécom Paris, deal with the bias and transparency of algorithms, a highly topical and particularly sensitive issue for users and regulators, at a time when these tools are increasingly common in everyday life.
