Thu, 02 Oct 2008 13:41:43 -0400 delallea Merged
Thu, 04 Sep 2008 13:48:47 -0400 delallea Fixed typo in help
Mon, 29 Sep 2008 16:04:51 -0400 delallea Typo fix in help
Fri, 25 Jul 2008 16:59:57 -0400 Thierry Bertin-Mahieux simple example of theano
Sat, 19 Jul 2008 14:26:24 -0400 Yoshua Bengio Fixed incorrect handling of slice column specifications in ArrayDataSet
Sat, 19 Jul 2008 14:12:41 -0400 Yoshua Bengio Added __len__ to HStackedDataSet and replaced default len() by sys.maxint instead of None
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

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 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

Tue, 06 May 2008 16:34:48 -0400 Frederic Bastien bugfix, we keep all the line, but only a some columns
Tue, 06 May 2008 16:01:53 -0400 Frederic Bastien by default, in a minibatch without any fixed number of batchs, we need to finish at the end of the dataset. Now we return a minibatch at the end event if this minibacht size != the gived minibatch_size.
Tue, 06 May 2008 13:57:36 -0400 Frederic Bastien in ArrayDataSet.__init__ if a columns is an index, we change it to be a list that containt only this index. This way, we remove the special case where the columns is an index for all subsequent call.
