parameterized_testcase-0.1
by Austin Bingham 10 Aug '11

10 Aug '11

I'm happy to announce the release of parameterized_testcase-0.1. This cunningly-named module allows you to generate unittest-compatible TestCases based on a collection of tests and various sets of parameters. This is an initial release. The code should work just fine, though the API may change/expand in the future. Documentation is a bit lacking, though that will change in future releases. You can get it here: http://code.google.com/p/parameterized-testcase/ Austin Bingham

pypiserver 0.2.0 - minimal pypi server
by Ralf Schmitt 10 Aug '11

10 Aug '11

Hi, I've just uploaded pypiserver 0.2.0 to the python package index. pypiserver is a minimal PyPI compatible server. It can be used to serve a set of packages and eggs to easy_install or pip. pypiserver is easy to install (i.e. just easy_install pypiserver). It doesn't have any external dependencies. http://pypi.python.org/pypi/pypiserver/ should contain enough information to easily get you started running your own PyPI server in a few minutes. The code is available on github: https://github.com/schmir/pypiserver Changes in version 0.2.0: - better matching of package names (i.e. don't install package if only a prefix matches) - redirect to the real pypi.python.org server if a package is not found. - add some documentation about configuring easy_install/pip -- Cheers, Ralf

ffnet-0.7 released
by Marek Wojciechowski 09 Aug '11

09 Aug '11

ffnet version 0.7 has been released and is available for download at: http://sourceforge.net/projects/ffnet/ This release contains couple of important changes: - neural network can be trained now using the power of multi-processor systems (see example mptrain.py) - attributes necessary for calculation of network derivatives are now generated only on demand; - data normalization limits are not changed when re-trainig with new data set; net.renormalize=True have to be set first; - compatibility with newest versions of numpy, scipy and networkx is enhanced; - support for *export to java* and *drawing network with drawffnet* is dropped. Basic API is left almost untouched. Exactly the same trainig scripts as for older versions should work without problems. What is ffnet? -------------- ffnet is a fast and easy-to-use feed-forward neural network training solution for python. Unique features present in ffnet -------------------------------- 1. Any network connectivity without cycles is allowed. 2. Training can be performed with use of several optimization schemes including: standard backpropagation with momentum, rprop, conjugate gradient, bfgs, tnc (with multiprocessing) and genetic alorithm based optimization. 3. There is access to exact partial derivatives of network outputs vs. its inputs. 4. Automatic normalization of data. Basic assumptions and limitations --------------------------------- 1. Network has feed-forward architecture. 2. Input units have identity activation function, all other units have sigmoid activation function. 3. Provided data are automatically normalized, both input and output, with a linear mapping to the range (0.15, 0.85). Each input and output is treated separately (i.e. linear map is unique for each input and output). 4. Function minimized during training is a sum of squared errors of each output for each training pattern. Performance ----------- Excellent computational performance is achieved implementing core functions in fortran 77 and wrapping them with f2py. ffnet outstands in performance pure python training packages and is competitive to 'compiled language' software. Incorporation of multiprocessing capabilities (tnc algorithm so far) makes ffnet ideal for large scale (really!) problems. Moreover, a trained network can be exported to fortran sources, compiled and called from many programming languages. Usage ----- Basic usage of the package is outlined below. See description of ffnet module and its functions (and especially ffnet class) for detailed explanations. >>> from ffnet import ffnet, mlgraph, savenet, loadnet, exportnet >>> conec = mlgraph( (2,2,1) ) >>> net = ffnet(conec) >>> input = [ [0.,0.], [0.,1.], [1.,0.], [1.,1.] ] >>> target = [ [1.], [0.], [0.], [1.] ] >>> net.train_tnc(input, target, maxfun = 1000) >>> net.test(input, target, iprint = 2) >>> savenet(net, "xor.net") >>> exportnet(net, "xor.f") >>> net = loadnet("xor.net") >>> answer = net( [ 0., 0. ] ) >>> partial_derivatives = net.derivative( [ 0., 0. ] ) Usage examples with full description can be found in examples directory of the source distribution. -- Marek Wojciechowski

PyCon US 2012 Survey - We need your input!
by Brian Curtin 09 Aug '11

09 Aug '11

Hi all, As we ramp up our efforts on PyCon US 2012, we wanted to gather some information from the community on what we can do best to serve you at the March 2012 conference in Santa Clara, CA. We've put together a survey about your experiences at past PyCons as well as what your interests are in the upcoming conference. We're interested in what speakers and topics you'd like to have at the tutorials, conference, and the poster sessions, as well as any input you have on what we can improve in other aspects of the event. If you have 5 minutes to spare, the survey is available at https://www.surveymonkey.com/s/pycon2012_launch_survey and results will be used to help us make PyCon 2012 the best conference yet. Thanks, The PyCon Organizers http://us.pycon.org/2012/
