Mon, 07 Jul 2008 12:02:34 -0400 Yoshua Bengio fixing merge
Thu, 19 Jun 2008 16:18:37 -0400 Joseph Turian Added more functions
Thu, 19 Jun 2008 12:35:41 -0400 Thierry Bertin-Mahieux dataset__call__() returns a FieldsSubsetDataSet, so still a subset of fields, but not cached any more. I added the function dataset.cached_fields_subset(self,*fieldnames) that returns the old version, cached, in case someone needs it. Current behaviour passes the tests.
Tue, 17 Jun 2008 17:12:43 -0400 Thierry Bertin-Mahieux Cached dataset seems debug, using n_batches... is n_batches around to stay?
Tue, 17 Jun 2008 16:47:33 -0400 Frederic Bastien debugged RenamedFieldsDataSet
Tue, 17 Jun 2008 14:46:10 -0400 Frederic Bastien bugfix, MinibatchDataSet.minibatches_nowrap() must raise StopIteration when needed
Tue, 17 Jun 2008 11:41:01 -0400 Frederic Bastien Automated merge with ssh://projects@lgcm.iro.umontreal.ca/hg/pylearn
Mon, 16 Jun 2008 17:26:51 -0400 Thierry Bertin-Mahieux n_minibatches in ArrayDataSet automatically computed

Mon, 16 Jun 2008 17:17:01 -0400 Thierry Bertin-Mahieux debugging when fieldnames = None, now -> fieldnames = fieldNames()
Mon, 16 Jun 2008 17:07:44 -0400 Frederic Bastien Automated merge with ssh://projects@lgcm.iro.umontreal.ca/hg/pylearn
Mon, 16 Jun 2008 16:59:35 -0400 Thierry Bertin-Mahieux sorry for all the debugging, this push should be the good one (and damn you *self*)
Mon, 16 Jun 2008 16:52:39 -0400 Thierry Bertin-Mahieux debug in an assert of minibatches
Mon, 16 Jun 2008 17:07:41 -0400 Frederic Bastien bugfix in RenamedDataSet
Mon, 16 Jun 2008 16:44:11 -0400 Thierry Bertin-Mahieux redone my previous hack in MinibatchToSingleExampleIterator, tests should work again
Mon, 16 Jun 2008 16:38:03 -0400 Thierry Bertin-Mahieux IMPORTANT: minibatches now returns minibatch_nowrap with a minimum of assert before. Should implement the good behavior, e.g. returning only complete batches and let the user figure out what he wants.
Mon, 16 Jun 2008 16:11:36 -0400 Thierry Bertin-Mahieux merge
Mon, 16 Jun 2008 16:03:16 -0400 Thierry Bertin-Mahieux little hack in MiniBatchToSingleExampleIterator, there was a problem which I think was not a bug, we were receiving [array(3)] and everything was crashing. Hack is kinda slow
Mon, 16 Jun 2008 16:06:59 -0400 Yoshua Bengio Added untested RenamedFieldsDataSet
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

Fri, 30 May 2008 10:19:16 -0400 delallea Hmm... that was committed by Fred I think, I got lost by Mercurial I think
Fri, 30 May 2008 10:14:46 -0400 delallea If I understand properly, the length of an unbounded stream is sys.maxint

Fri, 23 May 2008 16:01:01 -0400 Thierry Bertin-Mahieux should have solved the problem with minibatches not handling subsets of fieldnames, although maybe not super efficient
