Background:The analysis of COVID-19 infection data through the eye of physics-inspired Artificial Intelligence leads to a clearer understanding of the infection dynamics and assists in predicting future *** spreading of the pandemic during the first half of 2020 was curtailed to a larger or lesser extent through social distancing measures imposed by most *** the context of the standard Susceptible-Infected-Recovered(SIR)model,changes in social distancing enter through time-dependent infection ***:In this work we use machine learning and the infection dynamical equations of SIR to extract from the infection data the degree of social distancing and,through it,assess the effectiveness of the imposed ***:Quantitative machine learning analysis is applied to eight countries with infection data from the first viral *** find as two extremes Greece and USA where the measures were successful and unsuccessful,respectively,in limiting *** physics-based neural network approach is employed to the second wave of the infection,and by training the network with the new data,we extract the time-dependent infection rate and make short-term predictions with a week-long or even longer *** algorithmic approach is applied to all eight countries with good short-term *** data for Greece is analyzed in more detail from August to December ***:The model captures the essential spreading dynamics and gives useful projections for the spreading,both in the short-term but also for a more intermediate horizon,based on specific social distancing measures that are extracted directly from the data.
