Ruby Wrappers: RMagick, RTesseract (image manipulation and image recognition respectively) You can Google how to install those gems. Here was an example page of the dictionary. The shorthand translation was pretty much adjacent to the English word. require 'RMagick' require 'RTesseract' im = Magick::Image.read(file_

Sometimes it is unnecessary to load images in my selenium scripts. It takes time for the images (especially large ones) to load and messes up my sleep functions. Here's how to prevent it from loading. There are more options and it's listed in the All Profile

Part of my RelevantXKCD project writeup After I wrapped a simple Django server and posted it on Reddit in the subreddit /r/xkcd, I got some great feedback! For the Model As /u/drcopus helpfully enlightened me, I should've done data augmentation on the original training set. I

How I loaded the files in python I used joblib to save the files from sklearn.externals import joblib feature_list = count_vect.get_feature_names() model = "model105" joblib.dump(feature_list, model + '_vocabulary.pkl') joblib.dump(tfidf_transformer, model + '_transform.pkl') joblib.dump(
Machine Learning
Part of this entire writeup Goal Find a model to accurately predict a relevant XKCD given multiple words (a reddit comment). This essentially gave me a bunch of positively single-labeled data since each comment usually only had one "relevant XKCD" sub-comment attached. Example: Searching "Python" would
Data
So I embarked on a machine learning quest. Here are my notes on how I obtained the data. My first attempt a few months ago was to download the entire Reddit Corpus (in CSV form) and manually parse the comments. However, it soon became clear the my computer took way

So I embarked on a machine learning quest as a senior project. With all these advances in AI, I wanted to have some fun myself :P. You can view it here. I was inspired by Dan Zhang and Megan Ruthven's Relevant XKCD finder. They used ExplainXKCD to populate

This article requires knowledge of Ruby, the concept of webscraping, and HTML. Make sure you have Ruby installed (use RVM if you don't have it yet) -- I'm using 2.3.1 right now. If you want a reference sheet, I'm in the process
How To
My programming environment is quite nice on a chromebook. Although my chromebook is not the top of the line, ASUS C201 11.6 Inch, it does allow me to push some quick updates and do a bit of local testing for debugging. Note: When I compile and run, there is

Check out IMswimmer here! The thing with big non-profit organizations is that they usually split themselves into regional branches that have their own management and way of doing things. This means that there are very few standards that are permeated to all the regions. I've noticed this problem

So you want to do USACO? Make sure you actually like it and aren't doing it because you want it on your college resume! (See previous article) I'm going to assume that you understand USACO well enough and competed in some competitions/looked at some problems
Random Quips
Signatures are truly a work of art. As they mature through age, they become more flowing, graceful, and elegant. I remember the days during my childhood, when, after meticulously writing my name in cursive, I would broadly proclaim: "Look at this beautiful signature." It was a long journey
