About this

Hi everybody. My name is Matthew and I am currently working on my PhD Thesis about Recommender Systems at a university in Germany. This website is an online application demo of my recommendation engine (recalot.com). This demo uses view, ratings and click information for the computation of the recommendations. I distinguish users based on random ids which the system saves in the local storage of your browser. You can remove this id at any time by deleting your browser cookies. The quality of the computed recommendations may vary depending on which test algorithm currently is running. 

I do not own the images on this website and a click on the download button will refer you to the owning site, where you can choose your preferred measurements and download the wallpaper. Thank you that you use this site. 

Currently I'm using wallpapers from the following sites (my first results in google with the keyword: "wallpapers"):
