The keyword arguments given to make are optional and are used to

initial value is None.
At this point something special happens for our member Variables too.
In the 'acc' object, make allocates room to store numbers for m's member
Variables. By using the string 'state' as a keyword argument, we tell Theano to
store the number 0 for the member Variable called 'state'. By not mentioning
the 'inc' variable, we associate None to the 'inc' Variable.

# use up to two threads in the MKL routines
OMP_NUM_THREADS=2
# IMPORTANT!
# Use the local-temporary directory as a cache.
# If several jobs start simultaneously and use a common
# cache, then the cache may be corrupted.
# Theano is not process-safe or thread-safe in this sense.

You may also need to run the following from your shell:
.. code-block:: bash
module add python # for the current shell session
module initadd python # for this and future sessions
Lastly, if ``./filename.py`` doesn't work, try ``python filename.py``.

* that function saw its argument as being of type __main__.A, not a.A.
Incidentally, this behaviour is one of the big reasons to put autotests in
different files from the classes they test!
If all the test cases were put into <file>.py directly, then during the test
cases, all <file>.py classes instantiated by unit tests would have type
``__main__.<classname>``, instead of type ``<file>.<classname>``. This should never
happen under normal usage, and can cause problems (like the one you are/were
experiencing).

The following may go either in:
a) numpy refresher.
b) more details of broadcasting in the types section.
=== broadcastable ===
The {{{broadcastable}}} field of a {{{Tensor}}} must be a tuple of boolean values. Each value corresponds to a dimension of the {{{Tensor}}} and specifies whether the {{{Tensor}}} can be "broadcasted" along that dimension.
A value of {{{True}}} means two things:
* The size of the corresponding dimension will necessarily be 1.
* If needed, the {{{Tensor}}} can be ''broadcasted'' or ''replicated'' along the corresponding dimension to emulate a larger {{{Tensor}}}.
A value of {{{False}}} means that the corresponding dimension can take any nonnegative value and that the {{{Tensor}}} cannot be replicated along it (regardless of whether it is 1 or not).
Example: to define a ''row'' type, set broadcastable to {{{(True, False)}}}: this means the shape must be like {{{(1, n)}}}. If you add a row of shape {{{(1, n)}}} to a matrix of shape {{{(m, n)}}}, the row will be "broadcasted" or "replicated" {{{m}}} times along the first dimension, producing a virtual matrix of the correct size {{{(m, n)}}}. Therefore, adding a row to a matrix will add the row to each row of the matrix. If the value of {{{broadcastable}}} for the first dimension of the row was {{{False}}}, the operation would instead raise an exception complaining that the dimensions are not the same.
Similarly, the broadcastable pattern for a column is {{{(False, True)}}}: this means the shape must be like {{{(m, 1)}}}, therefore adding a column to a matrix will add that column to each column of the matrix. Several Ops, such as {{{DimShuffle}}}, can add or remove broadcastable dimensions.
The length of {{{broadcastable}}} is the number of dimensions of the {{{Tensor}}}.

- reliability of hosting service
Currently, [http://sharesource.org/ sharesource] and [http://www.assembla.com/ assembla] are the only hosting services that support mercurial that I know of. Sharesource is young, but supports all the required features. I'll make an account, and see what I can do with it...
Should we get a domain name? To my dismay, theano.org, theano.com and theano.net are all taken. The first two seem legit, but theano.net doesn't look like it has anything on it and expires on May 29, so maybe there's a chance we can snag it? -ob
We could also get [http://www.theano.io]. -jpt

There are instructions for how to backup a Trac site, i just haven't gotten
around to it. Currently, the whole directory is rsynced to the lisa account,
which is close to ok, but not quite.

Writing scripts to update p-omega1/.ssh/authorized_keys2 automatically from
certain user accounts' authorized_keys2 file. I've written this script, but not
really tested it.
Hooking up mercurial to trac would be nice, so we can associate commits and
tickets.
lgcm's uptime is usually about a week or two at max, so there's the pain in the
ass of having to re-log in, start up a screen session, find the directories,
restart trac, restart hg serve. We should be restarting hg serve for tlearn too
soon.
Even if I do set up the authorized_keys2 script to do the right thing, the users
on TRAC and the users on the system are totally independent, so adding a new
user is non-standard and only I can do it right now.
My choices seem to be:
- document all these hoops and good ideas
- fix them so they are easier to use and document
- replace them with hosting service
All of these options take time, mental effort, and the support of our
development group (look the large number of messages today on the topic)... so
i'm trying to find the least of all evils. The Right Thing doesn't seem to have
appeared yet.

Theano uses several tricks to obtain good performance:
* common sub-expression elimination
* [custom generated] C code for many operations
* pre-allocation of temporary storage
* loop fusion (which gcc normally can't do)
On my neural net experiments for my course projects, I was getting around 10x
speed improvements over basic numpy by using theano.
[More specific speed tests would be nice.]
With a little work, Theano could also implement more sophisticated
optimizations:
* automatic ordering of matrix multiplications
* profile-based memory layout decisions (e.g. row-major vs. col-major)
* gcc intrinsics to use MMX, SSE2 parallelism for faster element-wise arithmetic
* conditional expressions

Other software to look at and maybe recommend to users:
* [http://www.pytables.org/moin PyTables] - This is looking really
promising for dataset storage and experiment logging... This might
actually be useful for large data sets.
* [http://matplotlib.sourceforge.net/ MatPlotLib] - visualization tools
(plot curves interactively, like matlab's figure window)
* [http://www.pythonware.com/products/pil/ PIL] - Python Image Library:
write your matrices out in png! (Kinda a weird recommendation, I think)
* [http://www.logilab.org/857 pylint] - Syntax checker for python to
help beautify your code. (We'd be hypocrites to recommend this :)
* [http://www.winpdb.org/ Winpdb] - A Platform Independent Python
Debugger. (Except it doesn't really help you debug Theano graphs)
* [http://wiki.python.org/moin/IntegratedDevelopmentEnvironments Python Integrated Development Environments] - for all your coding needs

* Operators: "Since conversions to and from the COO format are
