... limited action space, but quickly become intractable for larger ones, as the planning time increases exponentially with the size of the action space. Significant planning time is therefore spend on actions ... Dismissing these actions before planning could therefore provide important computational gains. Instead of a direct policy optimisation over the full action space, our approach formali...

... Abstract We revisit the algorithm of Schütze (1995) for unsupervised part-of-speech tagging. The algorithm uses reduced-rank singular value decomposition followed by clustering to extract ... highest performances to date for fully unsupervised POS tagging. The revisited SVD-based approach presented here, which we call “two-step SVD” or SVD2, has four important characteristics....
