In Italy, the COVID-19 pandemic has fostered the adoption of cashless instruments making economic activity more resilient to adverse shocks. This study investigates whether the increased use of more innovative instruments has favoured the reduction of gaps in payments behaviour of vulnerable groups. Indeed, previous survey data show a general lower adoption of alternative instruments in the centre-south, by women, young people and those with lower education. Data from a survey conducted by the European Central Bank in July 2020 to measure the impact of the pandemic on payment habits (IMPACT) have been analysed through the main statistical models used for analysis of ordinal data. The assessment of cumulative link models describes the dependence of observed ordinal items on subjects’ covariates by taking into account the latent trait (payment attitudes) of respondents.
2. The inclusion of explainable AI approaches for well-being – theory and applications

The first approach examines, the problem with the financial literacy and how it influences quality of live expressed by emotional features. Which emotional features are affected and how intensely? Do financial literacy improvements mean significant improvement in these features? By explainable AI we explain, e.g., whether FL significantly influence feature A generally or in particular subdomains (levels) of FL and A. Moreover, the result is explained linguistically by short-quantified sentences of natural language.

Inclusion of AI approaches to diverse users’ categories
Explaniable AI should empower human beings and not replace them, i.e., help people to perform their job more efficiently. People with no statistical or informatics background and lack of trustworthiness have problems with inclusion of AI in their tasks due to black box models and solutions explained statistically. These solutions are understandable for people having a certain level of statistical literacy. Next, explainable AI solutions should be less data and energy demanding. Soft computing does not need: (i) extensive data sources (keeping privacy), (ii) a very high precision, and (iii) extensive computing, especially when human-in-the-loop is included (sustainable).

Composite indicators are the most popular choice for synthesizing an overall complex usually latent phenomenon. They have been grown in popularity and are applied in many fields from social aspects to environment, passing by the gender equality analysis whose increasing interest is justified also by the Goal 5 of the UN Agenda 2030.
As a gender index may be poor although easy to read, the potentiality to monitor the gender gap by using Bayesian networks (BNs) is discussed. This multivariate statistical tool is useful for describing variables relationships and their influence on the men-women distance. BNs are powerful tools for developing scenarios of sex-balancing and, thus, fruitful for decision-makers in orienting policies activated in different fields (i.e. economic, social and health) but simultaneously impacting on the gender gap. An example, carried out on Italian gender data at province-level is shown
4. AI: why diversity matters for an inclusive future
R. Johri – Head of R&D at HSBC & Founder of London Women in Machine Learning
AI and more specifically machine learning is now prevalent in almost every sector. Data by nature is biased and a machine learning model learns from patterns it finds in the data. If the data is biased, the model will be biased. Moreover, a study via AI Now indicated that female researcher representation in google and facebook is 10 and 15% respectively. This number drops lower when we deep dive into minority representations including people of color. There is a similarly low representation in academia. This implies that our models are being built in an environment that is not representative. Ironically you would not train a model without a representative sample, yet we accept a non representative environment. It is extremely important to incorporate views from diverse researchers, engineers and create a human centric feedback loop to ensure our data and hence models are not biased. The presentation touches on the more technical aspects of bias and the more human aspects of ethics.
5. Financial knowledge and the use of old and new financial instruments

The diffusion of the use of innovative instruments of payment and finance are one of the most important challenges of recent years, but a large part of population has difficulties due to lack of financial alphabetization.
