Social isolation during the COVID-19 pandemic in Spain: a population study.

Since March of 2020, billions of people worldwide have been asked to limit their social contacts in an effort to contain the spread of the SARS-CoV-2 virus. However, little research has been carried out to date on the impact of such social distancing measures on the social isolation levels of the population. In this paper, we study the impact of the pandemic on the social isolation of the Spanish population, by means of 32,359 answers to a citizen survey collected over a period of 7 months.

Most Wi-Fi fingerprinting localization methods presented in the literature are discriminative methods.
