Blogger: format your code (java, python, etc.) in your blog

I used prettyPrint to auto-format codes in my blogger. You don't need to download but link to it as follows:

Step 1:
Go to Customize -> Edit HTML, paste the following code inside tag <head> </head>


<link href='http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.css' rel='stylesheet' type='text/css'/>
<script src='http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.js' type='text/javascript'/>

Step 2:
Change tag <body> to <body onload='prettyPrint()'>

Step 3: How to use:
Put your code inside the following tag:

 <pre class="prettyprint"> 
<!-- your code here --> </pre>

Note that you can also change and upload your own css file and link to that address to format your code.

Pytorch and Keras cheat sheets

Sigmoid, tanh, ReLU functions. What are they and when to use which?

If you are working on Deep Learning or Machine Learning in general, you have heard of these three functions quite frequently. We know that they can all be used as activation functions in neural networks. But what are these functions and why do people use for example ReLU in this part, sigmoid in another part and so on? Here is a friendly introduction to these functions and a brief explanation of when to use which. Sigmoid function Output from 0 to 1 Exponential computation (hence, slow) Is usually used for binary classification (when output is 0 or 1) Almost never used (e.g., tanh is a better option) Tanh function A rescaled logistic sigmoid function (center at 0) Exponential computation Works better than sigmoid ReLU function (Rectified Linear Unit) and its variants Faster to compute Often used as default for activation function in hidden layers ReLU is a simple model which gives 0 value to all W*x + b < 0. The importance is that it introduces t...

Python Tkinter: Changing background images using key press

Let's write a simple Python application that changes its background image everytime you click on it. Here is a short code that helps you do that: import os, sys import Tkinter import Image, ImageTk def key(event): print "pressed", repr(event.char) event.widget.quit() root = Tkinter.Tk() root.bind_all(' ', key) root.geometry('+%d+%d' % (100,100)) dirlist = os.listdir('.') old_label_image = None for f in dirlist: try: image1 = Image.open(f) root.geometry('%dx%d' % (image1.size[0],image1.size[1])) tkpi = ImageTk.PhotoImage(image1) label_image = Tkinter.Label(root, image=tkpi) label_image.place(x=0,y=0,width=image1.size[0],height=image1.size[1]) root.title(f) if old_label_image is not None: old_label_image.destroy() old_label_image = label_image root.mainloop() # wait until user clicks the window except Exception, e: # Skip a...
