Dataviz, Machine Learning and Image Processing at

Held on November 10 and 11 in São Paulo, the third edition of Coda.Br (“Conferência anual de jornalismo de dados e métodos digitais”) featured more than 300 participants and dozens of hours of activities, including presentations and practical activities. I wasn’t able to assist, but fortunately, organizers gathered and shared all conference presentations in one place!

Here I highlight some lectures and workshops regarding subjects such as data visualization, machine learning and data visualization:

A computer sees a masterpiece

Uncompromisingly, I showed Edvard Munch’s “The Scream” to Google Cloud Vision API and, for my surprise, its computer vision algorithm “saw” an interesting aspect I guess most human eyes wouldn’t notice. The Cloud Vision API landscape feature, which detects popular natural and man-made structures within an image, printed out a bounding box along with the tag National Congress of Brazil in a specific area of the painting. Apparently, our Congress is a fright to the machine’s eyes.

Note: The Cloud Vision API doesn’t detect the National Congress of Brazil in all images of “The Scream” available on the web. The image I used was from this page.
