A short introduction to accountability in machine-learning algorithms under the GDPR

Artificial Intelligence (AI) can be defined as computer systems designed to solve a wide range of activities, that are “normally considered to require knowledge, perception, reasoning, learning, understanding and similar cognitive abilities” [1]. Having intelligent machines capable of imitating human’s actions, performances and activities seems to be the most common illustration about AI. One needs to recognise AI as being convoluted – thus, machine learning, big data and other terms as automatization must hold a seat when discussing AI.  Machine learning, for example, is defined as the ability of computer systems to improve their performance without explicitly programmed instructions: a system will be able to learn independently without human intervention [2]. To do this, machine learning develops new algorithms, different from the ones that were previously programmed, and includes them as new inputs it has acquired during the previous interactions.

The capabilities of machine learning may put privacy and data protection in jeopardy. Therefore, ascertaining liability would be inevitable and would imply the consideration of inter alia all plausible actors that can be called upon account.

Under the General Data Protection Regulation (GDPR), the principle of accountability is intrinsically linked to the principle of transparency. Transparency empowers data subjects to hold data controllers and processors accountable and to exercise control over their personal data. Accountability requires transparency of processing operations, however transparency does not constitute accountability [3]. On the contrary, transparency acts as an accountability’ helper – e.g. helping to avoid barriers, such as opacity.

Eurogroup and secrecy


by Andreia Barbosa, PhD student at the Law School of UMinho

It is clear from Article 1 of Protocol No 14, annexed to the Treaty on the Functioning of the European Union, that Eurogroup meetings take place informally.

Informality is reflected in two aspects. First, according to the terms in which the meetings are held, that is, as to the procedure adopted therein. In fact, there is no set of rules defining the procedure to be followed, for example, to ensure the involvement of all actors and to determine the order in which such interventions can be carried out and the duration they may have. Secondly, the terms in which «decisions» are taken and how they are made known to the public. It is through press conferences that the outcome of the meetings is presented to citizens of the Union (and when they are).

It should be noted that we refer to «decisions» as a result of Eurogroup meetings, even though we know that the formal, final, and binding decision on the subject is actually taken at the Ecofin meeting. However, we are also aware of the fact that the votes made at Ecofin express the outcome of the previous Eurogroup meeting. The final decision of Ecofin was born in the Eurogroup.

So, the informality resulting from Article 1 of Protocol No 14 actually means «opacity». Contrary to the idea of necessary transparency and publicity in all decision-making centers, no minutes or documents are signed in the Eurogroup, there are no transcripts or records relating to the respective meetings. No database has ever been set up to add up the «decisions» taken. The proposals under discussion, the presented votes, the conflicts of interest that have arisen and the commitments made are not known. Moreover, the acts of the Eurogroup can not be syndicated before the Court of Justice of the European Union, even though they are not documented, neither on paper nor in audio or video.

Although a certain procedural informality is admitted (but still susceptible of criticism), it does not seem to admit an opacity in the decisions. In abstract, a procedure can be informal and simultaneously transparent. In particular, the functioning of the Eurogroup may be informal, but its «decisions» should not be opaque. And the lack of transparency that exists goes beyond mere confidentiality.
