Classification of Explainable Artificial Intelligence Methods through Their Output Formats
Machine and deep learning have proven their utility to generate data-driven models with high accuracy and precision. However, their non-linear, complex structures are often difficult to interpret. Consequently, many scholars have developed a plethora of methods to explain their functioning and the logic of their inferences. This systematic review aimed to organise these methods into a hierarchical classification system that builds upon and extends existing taxonomies by adding a significant dimensionâthe output formats. The reviewed scientific papers were retrieved by conducting an initial search on Google Scholar with the keywords âexplainable artificial intelligenceâ; âexplainable machine learningâ; and âinterpretable machine learningâ. A subsequent iterative search was carried out by checking the bibliography of these articles. The addition of the dimension of the explanation format makes the proposed classification system a practical tool for scholars, supporting them to select the most suitable type of explanation format for the problem at hand. Given the wide variety of challenges faced by researchers, the existing XAI methods provide several solutions to meet the requirements that differ considerably between the users, problems and application fields of artificial intelligence (AI). The task of identifying the most appropriate explanation can be daunting, thus the need for a classification system that helps with the selection of methods. This work concludes by critically identifying the limitations of the formats of explanations and by providing recommendations and possible future research directions on how to build a more generally applicable XAI method. Future work should be flexible enough to meet the many requirements posed by the widespread use of AI in several fields, and the new regulation
Explainable Artificial Intelligence (XAI) 2.0: A Manifesto of Open Challenges and Interdisciplinary Research Directions
As systems based on opaque Artificial Intelligence (AI) continue to flourish
in diverse real-world applications, understanding these black box models has
become paramount. In response, Explainable AI (XAI) has emerged as a field of
research with practical and ethical benefits across various domains. This paper
not only highlights the advancements in XAI and its application in real-world
scenarios but also addresses the ongoing challenges within XAI, emphasizing the
need for broader perspectives and collaborative efforts. We bring together
experts from diverse fields to identify open problems, striving to synchronize
research agendas and accelerate XAI in practical applications. By fostering
collaborative discussion and interdisciplinary cooperation, we aim to propel
XAI forward, contributing to its continued success. Our goal is to put forward
a comprehensive proposal for advancing XAI. To achieve this goal, we present a
manifesto of 27 open problems categorized into nine categories. These
challenges encapsulate the complexities and nuances of XAI and offer a road map
for future research. For each problem, we provide promising research directions
in the hope of harnessing the collective intelligence of interested
stakeholders

Can NMT Understand Me? Towards Perturbation-based Evaluation of NMT Models for Code Generation
Neural Machine Translation (NMT) has reached a level of maturity to be
recognized as the premier method for the translation between different
languages and aroused interest in different research areas, including software
engineering. A key step to validate the robustness of the NMT models consists
in evaluating the performance of the models on adversarial inputs, i.e., inputs
obtained from the original ones by adding small amounts of perturbation.
However, when dealing with the specific task of the code generation (i.e., the
generation of code starting from a description in natural language), it has not
yet been defined an approach to validate the robustness of the NMT models. In
this work, we address the problem by identifying a set of perturbations and
metrics tailored for the robustness assessment of such models. We present a
preliminary experimental evaluation, showing what type of perturbations affect
the model the most and deriving useful insights for future directions.Comment: Paper accepted for publication in the proceedings of The 1st Intl.
