One of the most important issues related to artificial intelligence is the transparency of algorithms which are used in combination with a large amount of data. The potential impact of the use of algorithms on certain fundamental rights and public freedoms emphasizes the need for their transparency, with the aim of being able to limit abusive practices. More specifically, when assessing whether the use of algorithms can result in certain discriminatory practices, transparency as to how algorithms operate is essential. The growing importance of technological innovation brings an unprecedented contribution by algorithms in both the social and economic fields. This should be accompanied by transparency in order to ensure an effective protection of fundamental rights.
