Local Search, Semantics, and Genetic Programming: a Global Analysis
In recent years, a new mutation operator, Geometric Semantic Mutation with Local Search (GSM-LS), has been proposed to include a local search step in the mutation process based on the idea that performing a linear regression during the mutation can allow for a faster convergence to good-quality solutions.
Relating Implicit Bias and Adversarial Attacks through Intrinsic Dimension
Despite their impressive performance in classification, neural networks are known to be vulnerable to adversarial attacks.
A geometric analysis of the impact of large but finite switching rates on vaccination evolutionary games
In contemporary society, social networks accelerate decision dynamics causing a rapid switch of opinions in a number of fields, including the prevention of infectious diseases by means of vaccines.
Feedback control of social distancing for COVID-19 via elementary formulae
Social distancing has been enacted in order to mitigate the spread of COVID-19.
A behavioural modelling approach to assess the impact of COVID-19 vaccine hesitancy
In particular, the hesitancy and refusal of vaccination is better contained in case of large information coverage and small memory characteristic time.
Evidence of disorientation towards immunization on online social media after contrasting political communication on vaccines. Results from an analysis of Twitter data in Italy
Using a sentiment analysis on tweets posted in Italian during 2018, we aimed to: (i) characterize the temporal flow of vaccines communication on Twitter (ii) evaluate the polarity of vaccination opinions and usefulness of Twitter data to estimate vaccination parameters, and (iii) investigate whether the contrasting announcements at the highest political level might have originated disorientation amongst the Italian public.
