| 2.0.7 | Mar 3, 2012 | New Release | * Fixed a bug in the Generalized Expectation (GE) implementation for MaxEnt models. The old code could give low accuracy when using a small number of constraints. See the note at the top of this page for more information: http://mallet.cs.umass.edu/ge-classification.php * Fixed a bug in SVMLight2Vectors that could result in different Alphabets when importing multiple files at once. * Fixed a bug in SVMLight2Classify that allowed previously unobserved features to be added to the data Alphabet, possibly resulting in mismatching Classifier and InstanceList Alphabets. * Fixed bugs in the search direction computation in ConjugateGradient. * Added support for cross-validation in Vectors2Classify (in addition to random subsamples of the data set). * Added support for importing SVMLight data with Alphabets for which growth is stopped. * Added new options to Optimizers: it is now possible to set the convergence tolerance for GradientAscent, and set the LineOptimizer for LimitedMemoryBFGS |
