Machine Learning: 6 hours progress

Capture-6hrs17 March 2016

In CZ4041 Machine Learning assignment, my group has chosen to do a quite difficult data science challenge from Kaggle. I’ve been approaching it using Artificial Neural Network (Multi-layer perceptron to be exact). I’ve switched from using Pybrain library to Keras.io library. And since the raw training data is 10 GB, I pre-processed the data first and suddenly it became 26 GB. Phew, luckily I have lots of space in my hard drive. Now the challenge is how to fit those data in my 12-GB RAM. When I ran using Pybrain, I naively loaded the 10-GB raw data to the program and my computer frozen, like the good old days. Switching to Keras, it is more difficult to understand since there are much more configurations to set, but yeah I’ve been copy-pasting codes and doing trial-and-error with smaller dataset before doing this. So far, it seemed to be quite promising. Assuming the same speed, it will take 30+ hours to go. Hopefully it works.

I’ve woke up to a strange dream.

In this dream, I and some friends were preparing to celebrate someone’s birthday. And the theme was Star Wars! There was a simulation of a war just like Star Wars in a Virtual Reality, ’till the real fighting came, starting with one of us was shot dead in the head by a real bullet.

It’s just too violent, right?

Then, I realized that it was all in TV, while me watching it from my living room. Yet, the fighting scene was skipped “due to violence censorship in Indonesia” -_- You don’t censor my dream! :P

 

The Tale of Night Cycling

So, it was one of NTUBS Fellowship team’s initiative to do a night cycling starting on the night of 4 March 2016 till early morning of 5 March 2016. Nice experience, but cycling aside, I think that it gave us opportunity to see what Singapore at midnight looks like. …

Wikimedia Indonesia’s Pywikibot & Wikidata training

28 February 2016

On one fine day in January 2016, I was e-mailed by Siska Doviana, Wikimedia Indonesia’s Chairperson, an invitation to attend a workshop about Pywikibot and Wikidata on early March, in which the trip will be paid for by them. Initially I declined as the session date clashed with one of a planned NTUBS activity, but then there was an update that the workshop was shifted to 27 February, and it was great since it is the beginning of my recess week but I can’t stay there for long as there was NTUBS activity before (Dharma class) and after (meditation retreat) the workshop, and so I told them: I can only be there on Saturday morning and need to leave on Sunday. …

Coldplay at Super Bowl 50 Halftime Show

Such a short performance (~13 minutes), and yet ~4 minutes are “stolen” by Beyonce & Bruno Mars. Initially, I don’t really like it when they cut short the songs and skipping here & there. But after the show was given back to Coldplay in the end, I really love it, starting at around minute 10 they performed Clocks which transitioned into Fix You, and while on Fix You’s riff, they sang Up&Up chorus. This was really amazing. And it all ended with a grand “just believe in love”. :o :o :o
