It is important to know how the deep learning concepts work on a neural network to explain anything. There is a statute in the GDPR addressing the Artificial Intelligence/Automation issues.
The Right to Explanation of Automated Decision:
This rule gives the right to people to get explanations for automated decisions. If they are not satisfied or do not want to be part of such an algorithm, they can drop out. It can be an email marketing, loan approval or any kind of data based automated decision. This is a limitation for tech companies that depend on data for their decisions. So, in a way it limits the use of Artificial Intelligence development and marketing.
Neural networks learn by universal approximation and not model tuning. The more data they have, the greater the accuracy of predictions and decision-making. Neural networks are not explainable because of the black box issue. This causes a technical gap when it comes to GDPR statutes. Tech companies cannot explain how they use deep learning to come to a decision. So, unless this problem resolves, it is a loophole. This can definitely make it illegal for companies to practice AI and deep learning.
