Science and technology for the explanation of ai decision making.

The XAI project, focuses on the urgent open challenge of how to construct meaningful explanations of opaque AI/ML systems in the context of ai based decision making, aiming at empowering individual against undesired effects of automated decision making, implementing the “right of explanation”, helping people make better decisions preserving (and expand) human autonomy.

Black box AI systems for automated decision making, often based on ML over (big) data, map a user’s features into a class or a score without exposing the reasons why. This is problematic both for the lack of transparency and also for possible biases inherited by the algorithms from prejudices and collection artifacts hidden in the training data, which may lead to unfair or wrong decisions. The future of AI lies in enabling people to collaborate with machines, requiring good communication, trust, clarity, and understanding.

    This project aims at developing:
  1. an explanation infrastructure for benchmarking, equipped with platforms for the users' assessment of the explanations;
  2. an ethical-legal framework, in compliance with the provisions of the GDPR;
  3. a repertoire of case studies in explanation-by-design, mainly focused on health and fraud detection applications.

ParTree - Data Partitioning through Tree-based Clustering Method

Presenter: Riccardo Guidotti
Officine Garibaldi - il Cantiere delle Idee, Via Vincenzo Gioberti, 39, 56124 Pisa PI, Italy

When: 30/11/2023 at 11:30

Where: Officine Garibaldi. Stream details below.

Abstract: While existing clustering methods only provide the assignment of records to clusters without justifying the partitioning, we propose tree-based clustering methods that offer interpretable data partitioning through a shallow decision tree. These decision trees enable easy-to-understand explanations of cluster assignments through short and understandable split conditions. The proposed methods are evaluated through experiments on synthetic and real datasets and proved to be more effective than traditional clustering approaches and interpretable ones in terms of standard evaluation measures and runtime.

FIPER: a visual approach to explainability methods

Presenter: Eleonora Cappuccio
Officine Garibaldi - il Cantiere delle Idee, Via Vincenzo Gioberti, 39, 56124 Pisa PI, Italia


This seminar will present FIPER, a visualization tool that combines explanations through rules and feature importance.

An initial overview of the importance of designing human-centered explanations will be given. Use cases will be highlighted, and the results of a preliminary user test will be presented. The main purpose of the seminar will be to show and discuss new developments of the tool and possible applications.

Transformer models: from model inspection to applications in technical documentation

Abstract Language Models, of all sizes, have improved at a fast pace during the last years. However, besides measures of performance on downstream tasks, it is hard to understand what degree of linguistic knowledge they have and even more difficult to understand their inner workings.

Through linguistic probing of language models such as Bert and Roberta, I investigate their ability to encode linguistic properties and find a link between this ability and the phenomenon of outliers, parameters within language models that show unexpected behaviours. These findings help understand some of the properties that are typical of the attention mechanism at the core of such models.

Outliers also have a strong impact on the downstream performance of language models, therefore I apply these models to Named Entity Recognition in patents and study how they perform in this setting.

Finally, I present a brief study on the fine-tuning of Large Language Models to Italian.
