by IDSIA Announcements of talks＠IDSIA
Dear all,
On Thursday, December 21, we are organising at IDSIA USI-SUPSI a mini pre-Christmas workshop on the Philosophy of Machine Learning.
The meeting will be held in room C2.09, Sector C, second floor, Campus Est, USI-SUPSI, Lugano-Viganello
The programme is the following:
10.00 - 11.00: Talk by Juan Duran (TU Delft)
*Title: Justification, reliabilism, and machine learning
*Abstract: In this talk, I aim to explore the significance of justification in machine learning (ML). To begin, I'll briefly touch upon two promising epistemologies for ML—transparency and computational reliabilism (CR). However, my focus will be on defending the latter, requiring a more in-depth discussion. I'll dedicate some time to elucidate how CR operates, and which assumptions are built-in. Next, I plan to illustrate how CR works in the context of Forensic ML. This emerging field sparks debates about justification due to the inherent challenges in achieving both explanation and understanding, which are crucial for judicial and forensic purposes. Lastly, I'll address two objections against CR: i) the concern that, under CR, statistically insignificant yet serious errors can compromise the reliability of AI algorithms; and ii) the argument that CR, being a reliabilist epistemology, demands a high frequency of success, ultimately posing an issue of high predictive accuracy. I'll present arguments to counter these objections, advocating for computational reliabilism as a promising epistemology for ML.
11.00 - 12.00: Joint talk by Emanuele Ratti (Bristol) and Alberto Termine (IDSIA USI-SUPSI).
On the mediating role of XAI in scientific research
In recent years, philosophers have deserved increasing attention to the eXplainable AI (XAI) research programme. Surprisingly, their analyses focused more on the typologies and format of explanations delivered by XAI models, while little has been said about the potential epistemic roles of XAI in scientific research. In this talk, we will provide a novel framework to understand XAI in scientific research as a class of models that, rather than explaining, mediates. We call this framework ‘XAI-as-mediator’, and we will build on the literature on ‘models as mediators’ to pinpoint its characteristics. In particular, we argue that XAI models mediate between opaque models generated by ML algorithms and the domain/theoretical knowledge of the field to which models are applied.
In support to our thesis, we will analyse two examples of how XAI models can play the role of mediators. The first example focuses on the use of a specific family of XAI tools, namely feature selection methods, as support tools for post-hoc evaluation of ML models by domain experts. The second example, on the other hand, examines the use of XAI, and specifically counterfactual explanation methods, as tools to support hypothesis formulation during exploratory research. The talk is based on a joint work with Alessandro Facchini (IDSIA USI-SUPSI)

14.00 - 14.45: Talk by Andrea Ferrario (ETHZ)
*Title: The quest for justification in AI - where do we stand?
Establishing well-grounded beliefs about artificial intelligence (AI) and its capabilities is crucial, considering its widespread applications. However, existing research lacks a unified approach to the justification of these beliefs. I briefly review current literature, identifying challenges, and suggesting a few insights to advance the field.
14.45 - 15.45: Talk by Chiara Manganini (UniMI)
*Title: On the Ontology of Machine Learning Systems and its consequences for the taxonomy of Miscomputation
*Abstract: When compared to "traditional" computational artefacts, ML systems show a crucial difference in the role played by their function, discovered through the training process, rather than fixed from the beginning. This has deep implications for the notions of correctness and, consequently, of miscomputation in ML. By adapting the Ontology of the Levels of Abstraction, a revised framework is proposed to accommodate the essential features of ML systems. The result is a complex ontology composed of three artefacts: the Training Sample, the Training Engine, and the Machine Learning Model. This new ontological framework is then used to develop systematic insights into the types of ML errors, their relationship with non-ML miscomputations, and with fairness and explainability. The talk is based on joint works with Alberto Termine (IDSIA USI-SUPSI), and Giuseppe Primiero (UniMI).
