Where’s Waldo? Here he is!


Yesterday, I came across a nice article untitled “Here’s Waldo: Computing the optimal search strategy for finding Waldo“, written by Randal S. Olson. I used the data he shared to apply a correction to the kernel density estimation of Waldo’s location.

In this article, Randal explains that he has devoted some time to try to compute the optimal search strategy for finding Waldo. To that end, he has used some machine learning techniques.
From an image provided by Slate (Here’s Waldo, 2013, by Ben Blatt), Randal S. Olson retrieved the coordinates of 68 different locations of Waldo, and kindly shared the data afterwards.

Visualizing densities of spatial processes

In the past few weeks, Arthur Chaprentier (@freakonometrics) and I have been working again on an article untitled “Visualizing spatial processes using Ripley’s correction: an application to bodily-injury car accident location“.  The revised version of our work is available here: http://hal.archives-ouvertes.fr/hal-00725090.

Please note that this post is related to Arthur’s: http://freakonometrics.hypotheses.org/7129
