Feel free to substitute 'journals' for any other useful portal of knowledge.
I am interested in keeping an eye on new developments in machine learning, with a view to practical applications. I am not an academic seeking to publish my own work (at least not in this field), but I do want to be aware of potential new algorithms or tricks that would be useful on a practical level.
The only caveat is that the journal/conference proceeding or whatever must be freely available without requiring a subscription.
