Imbalanced data as risk factor of discriminating automated decisions: a measurement-based approach Journal Article

abstract = {Over the last two decades, the number of organizations -both in the public and private sector- which have automated decisional processes has grown notably. The phenomenon has been enabled by the availability of massive amounts of personal data and the development of software systems that use those data to optimize decisions with respect to certain optimization goals. Today, software systems are involved in a wide realm of decisions that are relevant for the lives of people and the exercise of their rights and freedoms. Illustrative examples are systems that score individuals for their possibility to pay back a debt, recommenders of the best candidates for a job or a house rent advertisement, or tools for automatic moderation of online debates. While advantages for using algorithmic decision making concern mainly scalability and economic affordability, on the other hand, several critical aspects have emerged, including systematic adverse impact for individuals belonging to minorities and disadvantaged groups. In this context, the terms data and algorithm bias have become familiar to researchers, industry leaders and policy makers, and much ink has been spelled on the concept of algorithm fairness, in order to produce more equitable results and to avoid discrimination. Our approach is different from the main corpus of research on algorithm fairness because we shift the focus from the outcomes of automated decision making systems to its inputs and processes. Instead, we lay the foundations of a risk assessment approach based on a measurable characteristic of input data, i.e. imbalance, which can lead to discriminating automated decisions. We then relate the imbalance to existing standards and risk assessment procedures. We believe that the proposed approach can be useful to a variety of stakeholders, e.g. producers and adopters of automated decision making software, policy makers, certification or audit authorities. This would allow for the assessment of the risk level of discriminations when using imbalanced data in decision making software. This assessment should prompt all the involved stakeholders to take appropriate actions to prevent adverse effects. Such discriminations, in fact, pose a significant obstacle to human rights and freedoms, as our societies increasingly rely on automated decision making. This work is intended to help mitigate this problem, and to contribute to the development of software systems that are socially sustainable and are in line with the shared values of our democratic societies.},

Using a data quality measurement approach combined with risk management, both defined in ISO standards, we focus on balance characteristics and we aim to understand how balance indexes (Gini, Simpson, Shannon, Imbalance Ratio) identify discrimination risk in six large datasets containing the classification output of ADM systems.
The best result is achieved using the Imbalance Ratio index. Gini and Shannon indexes tend to assume high values and for this reason they have modest results in both aspects: further experimentation with different thresholds is needed.
In terms of policies, the risk-based approach is a core element of the EU approach to regulate algorithmic systems: in this context, balance measures can be easily assumed as risk indicators of propagation – or even amplification – of bias in the input data of ADM systems.},

Indeed, the "bias in-bias out" problem represents one of the most significant risks of discrimination, which encompasses technical fields, as well as ethical and social perspectives. We contribute to the current studies of the issue by proposing a data quality measurement approach combined with risk management, both defined in ISO/IEC standards. For this purpose, we investigate imbalance in a given dataset as a potential risk factor for detecting discrimination in the classification outcome: specifically, we aim to evaluate whether it is possible to identify the risk of bias in a classification output by measuring the level of (im)balance in the input data. We select four balance measures (the Gini, Shannon, Simpson, and Imbalance ratio indexes) and we test their capability to identify discriminatory classification outputs by applying such measures to protected attributes in the training set. The results of this analysis show that the proposed approach is suitable for the goal highlighted above: the balance measures properly detect unfairness of software output, even though the choice of the index has a relevant impact on the detection of discriminatory outcomes, therefore further work is required to test more in-depth the reliability of the balance measures as risk indicators. We believe that our approach for assessing the risk of discrimination should encourage to take more conscious and appropriate actions, as well as to prevent adverse effects caused by the "bias in-bias out" problem.},

decisions in sensitive areas such as the granting of a bank overdraft, the susceptibility of an individual to a virus infection,

the risk of a potential discriminatory impact. In particular, machine-learning systems trained on unbalanced data could rise
to systematic discriminations in the real world. One of the most important challenges is to determine metrics capable of
detecting when an unbalanced training dataset may lead to discriminatory behaviour of the model built on it. In this paper,
we propose an approach based on the notion of data completeness using two different metrics: one based on the combinations
of the values of the dataset, which will be our benchmark, and the second using frame theory, widely used among others for
quality measures of control systems. It is important to remark that the use of metrics cannot be a substitute for a broader
design that must take into account the columns that could lead to the presence of bias in the data. The line of research does
not end with these activities but aims to continue the path towards a standardised register of measures.},

The aim is to determine the ranking order of a set of candidates maximizing utility bound to a fairness constraint. Our model extends the notion of protected attributes to a pool of individual circumstances, which determine the membership to a specific type. The contribution of this paper are i) a Fair-Distributive Ranking System based on criteria derived from distributive justice theory and its applications in both economic and social sciences; ii) a class of fairness metrics for ranking systems based on the Equality of Opportunity theory. We test our approach on a hypothetical scenario of a selection university process. A follow-up analysis shows that the Fair-Distributive Ranking System preserves an equal exposure level for both minority and majority groups, providing a minimal system utility cost.},

abstract = {Deep learning models contributed to reaching unprecedented results in prediction and classification tasks of Artificial Intelligence (AI) systems. However, alongside this notable progress, they do not provide human-understandable insights on how a specific result was achieved. In contexts where the impact of AI on human life is relevant (e.g., recruitment tools, medical diagnoses, etc.), explainability is not only a desirable property, but it is -or, in some cases, it will be soon-a legal requirement. Most of the available approaches to implement eXplainable Artificial Intelligence (XAI) focus on technical solutions usable only by experts able to manipulate the recursive mathematical functions in deep learning algorithms. A complementary approach is represented by symbolic AI, where symbols are elements of a lingua franca between humans and deep learning. In this context, Knowledge Graphs (KGs) and their underlying semantic technologies are the modern implementation of symbolic AI—while being less flexible and robust to noise compared to deep learning models, KGs are natively developed to be explainable. In this paper, we review the main XAI approaches existing in the literature, underlying their strengths and limitations, and we propose neural-symbolic integration as a cornerstone to design an AI which is closer to non-insiders comprehension. Within such a general direction, we identify three specific challenges for future research—knowledge matching, cross-disciplinary explanations and interactive explanations.},

abstract = {SeMi (SEmantic Modeling machIne) is a tool to semi-automatically build large-scale Knowledge Graphs from structured sources such as CSV, JSON, and XML files. To achieve such a goal, SeMi builds the semantic models of the data sources, in terms of concepts and relations within a domain ontology. Most of the research contributions on automatic semantic modeling is focused on the detection of semantic types of source attributes. However, the inference of the correct semantic relations between these attributes is critical to reconstruct the precise meaning of the data. SeMi covers the entire process of semantic modeling: (i) it provides a semi-automatic step to detect semantic types; (ii) it exploits a novel approach to inference semantic relations, based on a graph neural network trained on background linked data. At the best of our knowledge, this is the first technique that exploits a graph neural network to support the semantic modeling process. Furthermore, the pipeline implemented in SeMi is modular and each component can be replaced to tailor the process to very specific domains or requirements. This contribution can be considered as a step ahead towards automatic and scalable approaches for building Knowledge Graphs.},

Inthis paper, we present a novel approach based onGraph Neural Networks (GNNs) to build seman-tic models of data sources. GNNs are trained onLinked Data (LD) graphs, which serve as back-ground knowledge to automatically infer the se-mantic relations connecting the attributes of a datasource. At the best of our knowledge, this is thefirst approach that employs GNNs to identify thesemantic relations. We tested our approach on 15target sources from the advertising domain (usedin other studies in the literature), and comparedits performance against two baselines and a tech-nique largely used in the state of the art. Theevaluation showed that our approach outperformsthe state of the art in cases of data source withthe largest amount of semantic relations definedin the ground truth.},

abstract = {Payment channel networks are the most developed proposal to address the well-known issue of blockchain scalability. Currently, the Lightning Network (LN) is the mainstream and most used payment channel network. In a previous work we introduced CLoTH, a payment channel network simulator we developed to analyze capabilities and limitations of such networks. In this work, using CLoTH, we present results of three groups of simulations on a recent snapshot of the LN, aimed to shed a light on the following aspects. Firstly, we investigated how hubs influence the LN performance. Then, we analyzed the effectiveness of two different channel rebalancing approaches, an active and a passive one. Eventually, we studied performance of the LN when a few service-providers nodes receive payments from the other network nodes, which is a typical use case of payment channel networks. We found that the LN is resilient to the removal of hubs, that our passive rebalancing approach reduces of about one fourth the payments failures due to channel unbalancing, and that in the service-providers scenario a consistent part of payments fails because channels directing to the service providers become unbalanced. Our work contributes to prove the strengthen of the Lightning Network when removing hubs and its weakness in the service-provider scenario. In addition, the passive rebalancing approach proposed in this work is a good candidate for the implementation in the Lightning Network protocol to mitigate channel unbalancing.},

abstract = {Context: The technical debt (TD) concept inspires the development of useful methods and tools that support TD identification and management. However, there is a lack of evidence on how different TD identification tools could be complementary and, also, how human-based identification compares with them.
Objective: To understand how to effectively elicit TD from humans, to investigate several types of tools for TD identification, and to understand the developers’ point of view about TD indicators and items reported by tools.
Method: We asked developers to identify TD items from a real software project. We also collected the output of three tools to automatically identify TD and compared the results in terms of their locations in the source code. Then, we collected developers’ opinions on the identification process through a focus group.
Results: Aggregation seems to be an appropriate way to combine TD reported by developers. The tools used cannot help in identifying many important TD types, so involving humans is necessary. Developers reported that the tools would help them to identify TD faster or more accurately and that project priorities and current development activities are important to be considered together, along with the values of principal and interest, when deciding to pay off a debt.
Conclusion: This work contributes to the TD landscape, which depicts an understanding between different TD types and how they are best discovered.},

abstract = {Background: Effort estimations are critical tasks greatly influencing the accomplishment of software projects. Despite their recognized relevance, little is yet known what indicators for inaccurate estimations exist, and which are the reasons of inaccurate estimations. Aims: In this manuscript, we aim at contributing to this existing gap. To this end, we implemented a tool that combines data analytics and developers’ feedback, and we employed that tool in a study. In that study, we explored the most common reasons of inaccurate user story estimations and the possible indicators of inaccurate estimations. Method: We relied on a mixed method approach used to study reasons and indicators for the identification and prediction of inaccurate estimations in practical agile software development contexts. Results: Our results add to the existing body of knowledge in multiple ways. We elaborate causes for inaccurate estimations going beyond the borders of existing literature; for instance, we show that lack of developers’ experience is the most common reason of inaccurate estimations. Further, our results suggest, for example, that the higher the complexity, the higher the uncertainty in the estimation. Conclusions: Overall, our results strengthen our confidence in the usefulness of using data analytics with human-in-the-loop mechanisms to improve effort estimations.},

abstract = {Requirements Engineering (RE) has established itself as a software engineering discipline over the past decades. While researchers have been investigating the RE discipline with a plethora of empirical studies, attempts to systematically derive an empirical theory in context of the RE discipline have just recently been started. However, such a theory is needed if we are to define and motivate guidance in performing high quality RE research and practice.We aim at providing an empirical and externally valid foundation for a theory of RE practice, which helps software engineers establish effective and efficient RE processes in a problem-driven manner.We designed a survey instrument and an engineer-focused theory that was first piloted in Germany and, after making substantial modifications, has now been replicated in 10 countries worldwide. We have a theory in the form of a set of propositions inferred from our experiences and available studies, as well as the results from our pilot study in Germany. We evaluate the propositions with bootstrapped confidence intervals and derive potential explanations for the propositions.
In this article, we report on the design of the family of surveys, its underlying theory, and the full results obtained from the replication studies conducted in 10 countries with participants from 228 organisations. Our results represent a substantial step forward towards developing an empirical theory of RE practice. The results reveal, for example, that there are no strong differences between organisations in different countries and regions, that interviews, facilitated meetings and prototyping are the most used elicitation techniques, that requirements are often documented textually, that traces between requirements and code or design documents are common, that requirements specifications themselves are rarely changed and that requirements engineering (process) improvement endeavours are mostly internally driven. Our study establishes a theory that can be used as starting point for many further studies for more detailed investigations. Practitioners can use the results as theory-supported guidance on selecting suitable RE methods and techniques.},

Several researchers have found various discriminatory practices related to the use of human-related machine learning systems, for example in the field of criminal justice, credit scoring and advertising. Fair machine learning is therefore emerging as a new field of study to mitigate biases that are inadvertently incorporated into algorithms. Data scientists and computer engineers are making various efforts to provide definitions of fairness. In this paper, we provide an overview of the most widespread definitions of fairness in the field of machine learning, arguing that the ideas highlighting each formalization are closely related to different ideas of justice and to different interpretations of democracy embedded in our culture. This work intends to analyze the definitions of fairness that have been proposed to date to interpret the underlying criteria and to relate them to different ideas of democracy.},

abstract = {This paper deals with the search of optimal paths in a multi-stage stochastic decision network as a first application of the deterministic approximation approach proposed by Tadei et al. (2019). In the network, the involved utilities are stage-dependent and contain random oscillations with an unknown probability distribution. The problem is modeled as a sequential choice of nodes in a graph layered into stages, in order to find the optimal path value in a recursive fashion. It is also shown that an optimal path solution can be derived by using a Nested Multinomial Logit model, which represents the choice probability at the different stages. The accuracy and efficiency of the proposed method are experimentally proved on a large set of randomly generated instances. Moreover, insights on the calibration of a critical parameter of the deterministic approximation are also provided.},

abstract = {Purpose: This paper aims to analyze the limitations of the mainstream definition of artificial intelligence (AI) as a rational agent, which currently drives the development of most AI systems. The authors advocate the need of a wider range of driving ethical principles for designing more socially responsible AI agents.
Design/methodology/approach: The authors follow an experience-based line of reasoning by argument to identify the limitations of the mainstream definition of AI, which is based on the concept of rational agents that select, among their designed actions, those which produce the maximum expected utility in the environment in which they operate. The problem of biases in the data used by AI is taken as example, and a small proof of concept with real datasets is provided.
Findings: The authors observe that biases measurements on the datasets are sufficient to demonstrate potential risks of discriminations when using those data in AI rational agents. Starting from this example, the authors discuss other open issues connected to AI rational agents and provide a few general ethical principles derived from the White Paper AI at the service of the citizen, recently published by Agid, the agency of the Italian Government which designs and monitors the evolution of the IT systems of the Public Administration.
Originality/value: The paper contributes to the scientific debate on the governance and the ethics of AI with a critical analysis of the mainstream definition of AI.},

abstract = {Many software systems today make use of large amount of personal data to make recommendations or decisions that affect our daily lives. These software systems generally operate without guarantees of non-discriminatory practices, as instead often required to human decision-makers, and therefore are attracting increasing scrutiny. Our research is focused on the specific problem of biased software-based decisions caused from biased input data. In this regard, we propose a data labeling framework based on the identification of measurable data characteristics that could lead to downstream discriminating effects. We test the proposed framework on a real dataset, which allowed us to detect risks of discrimination for the case of population groups.},

abstract = {The Lightning Network (LN) is one of the most promising off-chain scaling solutions for Bitcoin, as it enables off-chain payments which are not subject to the well-known blockchain scalability limit. In this work, we introduce CLoTH, a simulator for HTLC payment networks (of which LN is the best working example). It simulates input-defined payments on an input-defined HTLC network and produces performance measures in terms of payment-related statistics (such as time to complete payments and probability of payment failure). CLoTH helps to predict issues and obstacles that might emerge in the development stages of an HTLC payment network and to estimate the effects of an optimisation action before deploying it. We conducted simulations on a recent snapshot of the HTLC payment network of LN. These simulations allowed us to identify network and payments configurations for which a payment is more likely to fail than to succeed. We proposed viable solutions to avoid such configurations.},

abstract = {Questo documento è il risultato del primo laboratorio sull’innovazione critica del Progetto Punto Zero, ‘Persuasori social’, svoltosi tra novembre 2017 e aprile 2018, che ha visto la partecipazione di una serie di portatori di interesse, tra cui partiti politici, agenzie di comunicazione, autorità indipendenti, iattaforme digitali, sindacati, ordini professionali, giornalisti ed esperti. Tutti questi soggetti sono stati coinvolti per stimolare un dibattito informato su come, concretamente, ciascuno può contribuire alla creazione di strumenti e soluzioni che garantiscano il buon funzionamento dei meccanismi democratici.
Con il lavoro del team di Punto Zero, e grazie alla collaborazione attiva degli stakeholder, il progetto ha affrontato il tema, oggi più spinoso che mai, della trasparenza e del rispetto delle tutele democratiche nelle campagne politiche digitali:
— fornendo un rapporto dettagliato sullo stato dell’arte delle conoscenze scientifiche e dei fatti di attualità rilevanti in materia, così da costruire un terreno di conoscenze comuni per una successiva discussione informata e consapevole con e tra i partecipanti (gli “stakeholder”);
— riassumendo i contributi forniti dagli stakeholder, sia nelle interviste individuali a loro effettuate dal team di Punto Zero nel corso dei mesi di febbraio e marzo 2018, sia negli incontri plenari tenutisi a gennaio, marzo e aprile 2018;
— formulando una serie di raccomandazioni concretamente attuabili, nella politica come nelle istituzioni, che distillino quanto emerso nel dibattito ragionato tra stakeholder; tali raccomandazioni sono organizzate secondo tre categorie: interventi e soluzioni positive più o meno largamente condivise dai partecipanti, interventi e soluzioni comunemente ritenute da evitare, e temi su cui invece si è riscontrato un più ampio spettro di opinioni divergenti.
Il team di progetto ha inoltre partecipato ai lavori del “Tavolo Tecnico per la garanzia del pluralismo e della correttezza dell’informazione sulle piattaforme digitali” istituito dall’Autorità per le Garanzie nelle Comunicazioni.},

Tutto questo si inserisce all’interno di un quadro più ampio di riflessione sulle politiche da mettere in atto per favorire la trasformazione digitale, motore di sviluppo sociale, economico e culturale.
Per accelerare questo processo di trasformazione è possibile ispirarsi a esperienze internazionali che hanno portato risultati tangibili: l’Italia deve eccellere nella ricerca di strategie innovative, magari capaci di nutrirsi della ricchezza storica, culturale e sociale del Paese e del Mediterraneo e allo stesso tempo riuscire a cogliere quanto di meglio sia emerso dalle strategie di quegli Stati che, per primi, hanno saputo fare dell’evoluzione dell’informatica pubblica la leva per la transizione verso un nuovo assetto globale di economia e società.
È, quindi, necessario sostenere le forze di innovazione del Paese per ottenere modelli sempre più competitivi e avviare un cambiamento radicale delle modalità di relazione tra cittadini, amministrazioni e mercato. L’obiettivo finale di questo processo è la creazione di servizi pubblici moderni, di semplice utilizzo, accessibili, di qualità, orientati dunque alla comprensione dei bisogni degli utenti, che permettano quindi di accrescere il livello di soddisfazione del cittadino e la fiducia nelle istituzioni.
Il documento intende delineare le prospettive di sviluppo dei servizi pubblici digitali e le sfide che il Paese dovrà affrontare per implementare e adoperare le nuove tecnologie nel rispetto dell’etica e delle leggi mettendo il cittadino al centro di questo percorso evolutivo.},
