Breaking a simple text based CAPTCHA

It took me about a week of my Dashain vacation to make this simple captcha breaker (5 days to be exact). I had been reading Image Processing in my CS undergrad for some time then, and wanted to put my skills to use, although, I must admit, its not as overly complicated or full of image processing bits as I'd have likely enjoyed. I had only learned the basics when I started doing this. If I were to do it now, I would have definitely done it differently. read more

Handwritten Devanagari Digit Recognition using Neural Network

Neural Network was one of the electives available during my 5th semester, and knowing that it was available, I was certain that I wanted to study it over any other electives. But, unfortunately (or fortunately), my college, as it is with many other colleges of Nepal, made it a compulsion to take Cryptography as the elective subject. I, obviously, wanted to study Neural Net and could not convince the college on teaching ANN instead of Cryptography. I was left with no choice but to study both, which I did. A few of us studied both the subjects as an elective. Since the teacher was not available during the weekdays, we took classes on every weekend for 3 hours each. So, there were no holidays for us, for 4 months, I think. read more

Devanagari Handwritten Character Dataset

I used this dataset while doing a project for my undergrad coursework of Neural Network. We had to implement a handwritten digit recognition neural net using the MNIST dataset. Upon accomplishing it, I looked around for Devanagari dataset and found one located at, which seems to have expired as of this moment. read more

Grab PacktPub Free Learning eBook Everyday Automatically

Packt Publishing have a lot of good premium books and everyday they put up a premium book for download for free. You could get a premium book a day by going to the Free Learning eBook page.

List of Nepali data sources

Hi guys, its been a long time. I am tired of making empty promises (regarding posting regularly) so, let me not do it again. While I was beginning my data-science journey, I tried to collect as many sources for Nepali datasets as possible, and the following is the listing of the same. The problem is most of these datasets are in PDF (most are in a booklet), so you'd have to use some extraction utilities such as Tabula to convert it into a CSV or workable file format. read more

How To Disable Bing Translator on Twitter

Bing Translator automatically translates non-English posts on Facebook and Twitter. As much as I'd like to appreciate the feature, it is very unreliable service. I'm not sure about you guys, but I have never seen Bing translate even one word of my language (Nepali) correctly. I'd rather not see incorrect translations on my news feed. read more
