It is important to note that all the "running" calculations are done for full windows. Here is a simple example:</p> <p>y = [1, 2, 3, 3, 1, 4], with a sliding window of size = 3 for the running estimations, means = 2, 2.6667, 2.3333, 2.6667 medians = 2, 3, 3, 3 modes = 1, 3, 3, 1</p> Simple Back-propagation Neural Network in Python source code (Python) 2012-05-30T17:09:49-07:00David Adlerhttp://code.activestate.com/recipes/users/4182015/http://code.activestate.com/recipes/578148-simple-back-propagation-neural-network-in-python-s/ <p style="color: grey"> Python recipe 578148 by <a href="/recipes/users/4182015/">David Adler</a> (<a href="/recipes/tags/back/">back</a>, <a href="/recipes/tags/back_propagation/">back_propagation</a>, <a href="/recipes/tags/neural/">neural</a>, <a href="/recipes/tags/neural_network/">neural_network</a>, <a href="/recipes/tags/propagation/">propagation</a>, <a href="/recipes/tags/python/">python</a>). </p> <p>This is a slightly different version of this <a href="http://arctrix.com/nas/python/bpnn.py" rel="nofollow">http://arctrix.com/nas/python/bpnn.py</a></p> Backpropagation-ANGN source code (Python) 2012-10-03T20:59:44-07:00David Adlerhttp://code.activestate.com/recipes/users/4182015/http://code.activestate.com/recipes/578278-backpropagation-angn-source-code/ <p style="color: grey"> Python recipe 578278 by <a href="/recipes/users/4182015/">David Adler</a> .

They can be displayed via help(obj). However, they can not contain images. This recipe allows the inclusion of images (encoded in base 64 in the Python file) inside docstrings in a transparent way. The images are indicated as "docpicture = file_name.ext" inside the docstring, and the encoded data is in variable "file_name" inside the same module.</p> sshfs mount tool (Python) 2008-06-24T07:31:22-07:00Sven BrĂ¶cklinghttp://code.activestate.com/recipes/users/4158983/http://code.activestate.com/recipes/573473-sshfs-mount-tool/ <p style="color: grey"> Python recipe 573473 by <a href="/recipes/users/4158983/">Sven BrĂ¶ckling</a> . </p> <p>This script uses sshfs ans fusermount to mount ssh ressources to local filesystems.

This is a base class that you use to define your class (and methods for each function). It uses Sam Rushings calldll, cstring and membuf modules but I think it will make interfacing with any DLL much easier for the beginner (especially for the first time).</p>
