<p>What about the following article on <em><a href="http://en.wikipedia.org/wiki/Collaborative_filtering" rel="nofollow">collaborative filtering</a></em> (from what I seem to remember, there were some questions dealing with that topic in the past)?</p>

<p>The <a href="http://cran.r-project.org/web/packages/recommenderlab/" rel="nofollow">recommenderlab</a> R package, from Michael Hahsler, seems to implement some algorithms for recommendation systems (see also the accompanying <a href="http://cran.r-project.org/web/packages/recommenderlab/vignettes/recommenderlab.pdf" rel="nofollow">vignette</a>).</p>

<p>About a possible date, I would suggest avoiding Friday the 31st. So, if the next CVJC has to be held next week, I would rather suggest Wednesday or Thursday. But maybe we could expect a better participation rate the week after; that is, Friday the 7th?</p>
