If I put the the windowed_paginating links in for the paginating_links_each def. It then tells me to put the shared/_paginate.rhtml into my application_helper.rb file. Do I just copy the code and put it in there after module ApplicationHelper then Code then end?. In my view where I use the paginating-find I have Visits#index Find me in app/views/visits/index.html.erb All My Visits for - You have no Visits "visits", :action => "new" } %> 'show', :id => c.id %> So i am not sure how to use the partials and so I get my links to the show action and then the links to the other pages in the pagination. Any help would be greatly appreciated. - Owen Hello I am working on my first RonR project and I am using paginating_find and it is working well, but I want to use your code so It will have next - previous links instead of 12..etc

Visits#index
Find me in app/views/visits/index.html.erb

All My Visits for -

You have no Visits

“visits”, :action => “new” } %>

’show’, :id => c.id %>

So i am not sure how to use the partials and so I get my links to the show action and then the links to the other pages in the pagination. Any help would be greatly appreciated. - Owen

]]> Comment on SVD Recommendation System in Ruby by Ilya Grigorik http://www.igvita.com/2007/01/15/svd-recommendation-system-in-ruby/#comment-106366 Ilya Grigorik Fri, 18 Jul 2008 12:38:11 +0000 http://www.igvita.com/blog/2007/01/15/svd-recommendation-system-in-ruby/#comment-106366 It's hard to generalize between SVD, k-NN, or any other algorithm for that matter - it all depends on the dataset. Depending on the properties, sometimes a simple decision tree can often outperform the rest. Looking at the Netflix challenge: some of the most successful early attempts were with k-NN algorithms, SVD folks have had moderate success as well. However, now the trend seems to be towards blending: combining these predictors to capture latent variables and hence improve the performance. Machine Learning is as much black art as it's science. ;) It’s hard to generalize between SVD, k-NN, or any other algorithm for that matter - it all depends on the dataset.

Felipe, 37Signals had an insightful view on this (I think): you obviously need vision of what you are building, but also don't worry about satisfying and logging every user request. Your users won't let you forget about the features that really matter. Re: unique feed. Awesome, and thanks! David, the only cautionary note I would add around it: you see a lot of startups fizzle after they get their funding. Sometimes, that cash creates a false sense of security - as if, you've already got it made. Wrong. Declan, those are great tips. We've been using sprint burndowns, but I like the idea of a release (or even further) burndown chart - definitely something I'll try in the future. It's also interesting that you've brought up the stifiling angle, because that's the most common response from the developers: "but where's the fun in that?" Somehow we equate product focus to rote execution, which is obviously not the case. Elise, that’s a great point: Vision = Focus.

One thing that makes me wonder is how does SVD compare to k-NN in terms of performance and quality i.e. which one should give better results in general. Are there betters ways in collaborative filtering field or folks at amazon or netflix probably use just modifications of those as well? Could you shed some light on that? Thanks. Really great post Ilya!
