[Oct 9th 2019] LabMeeting: Pseudo-Random Numbers Generation – a Reinforcement Learning approach

Luca Pasqualini (DIISM, University of Siena) Oct 9, 2019 – 11:00 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description Pseudo-Random Numbers Generators (PRNGs) are algorithms produced to generate long sequences of statistically uncorrelated numbers, i.e. pseudo-random numbers (PRNs). Those numbers are used in mid-level cryptography and in many software applications and libraries. Test […]
