While not open journals per se, many (new) papers will typically be available at academic homepages (preprints), via "All [X] versions"-links in a google scholar [0] search, or on arXiv [1], depending on the subfield. For instance, the machine learning group (Yoshua Bengio, Ian Goodfellow, et al.) at the University of Montreal (the people behind open source software like Theano [2], Pylearn 2 [3], etc.) regularly makes papers available on arXiv, and is currently working on a book about Deep Learning, drafts of which are freely available [4].
