    Poetry


In my free time, I write poetry in English, classical Arabic or in the Moroccan dialect. It is possible to combine poetry and Statistics. In January 2022, my former PhD student Yulia Kulagina and myself collected the lyrics of 63 songs by Frank Sinatra from Musixmatch. A mixture distribution was fitted to the frequency of the words'occurrences. New words were generated based on the fitted mixture. The generated words were put together into a new poem that we entitled Young.
The poem can be found here.
In June 2022, two singers (Jazz and Soprano) performed the poem to the music of New York, New York. Due to copyright issues, their performance cannot be made public. If you have interest in composing a new music, please write to me at fadouab@ethz.ch
