The Picasso Experiment
With a team consisting of Ettore Majorana, Andrea Giansanti, Davide Iannuzzi and Maurits Kaptein, we are currently investigating how people perceive beauty, complexity, and symmetry in paintings. To get a better feel for the subject, …
Start coding for Bobbi – the open source ECG monitor
. I was asked to put some basic code examples online to help developers get started with the Totem Bobbi Motion + ECG Monitor. For those not in the know: “The Bobbi” is a very …
Decoy Effect LiF simulation in R
We ran the R simulation below to test our hypothesis that LiF should be able to optimize decoy effects (I will add comments further clarifying my train of thought as reflected by the script within …
Where lock-in feedback finds and tracks optimal selling price
After my bare bones Python implementation of Davide Iannuzzi’s and Maurits Kaptein’s “Lock in Feedback” (LiF) algorithm, I thought it interesting to get a better feel for the algorithm’s capabilities and constraints by putting it …
