Thu, 12 Jun 2008 12:45:42 -0400 Thierry Bertin-Mahieux small bugs fixed with NArrayDataSet
Thu, 12 Jun 2008 12:35:47 -0400 Thierry Bertin-Mahieux NArraysDataSet improved, use arrays instead of matrix, also a dictionnary of field indexes
Wed, 11 Jun 2008 17:11:37 -0400 Thierry Bertin-Mahieux bug fixed when initializing NArraysDataSet with 1-d arrays. This now raises an Exception
Wed, 11 Jun 2008 17:05:56 -0400 Thierry Bertin-Mahieux bug fixed when one matrix is an array, a 1-d matrix
Wed, 11 Jun 2008 16:59:03 -0400 Thierry Bertin-Mahieux NArraysDataSet, a generalization ArrayDataSet where every field is a ndarray, is implemented. Not really tested aside basic stuff...
Wed, 11 Jun 2008 16:40:47 -0400 Thierry Bertin-Mahieux doc updated regarding __getitem__ returning LookupList and .subset returning a DataSet
Wed, 11 Jun 2008 16:28:09 -0400 Thierry Bertin-Mahieux getitem in ArrayDataSet is set up again, supposed to be faster than default one, has been tested agains the default behaviour. In particular, now always return a LookupList
Wed, 11 Jun 2008 13:57:34 -0400 Thierry Bertin-Mahieux bug fixed concerning the slicing, now ds[0:len(ds) + 1000 : 2] is accepted, same a python list
Wed, 11 Jun 2008 13:53:39 -0400 Thierry Bertin-Mahieux behaviour is now the same as a list in pylearn, so if len(ds) = 10, ds[10] raise an IndexError, same thing for ds[[1,10]], and ds[0:14:1] returns 10 elements
Wed, 11 Jun 2008 11:43:54 -0400 Thierry Bertin-Mahieux dataset.subset implemented
Wed, 11 Jun 2008 11:18:14 -0400 Thierry Bertin-Mahieux get item now returns LookupLists
