“Most of the past week has been spent convincing myself that it doesn’t really matter how I analyse my data because the results come out the same regardless. This is reassuring for me, but it doesn’t mean that somebody else, looking at my data with fresh eyes and a different perspective, would not come to an entirely different set of conclusions.”

Eureqa looks for possible equations that explain the relation of some likely pieces of data, and then tweaks and tests those equations to see if the results more accurately fit the data. It keeps iterating until it has an equation that works.’

#architecture – IBM’s Architecture for Astronomical Big Data

‘A main design challenge is how to process one Exabyte of raw data per day. This is the data amount anticipated when the SKA system as the world’s largest and most sensitive radio telescope will be ready; it’s construction will start in 2016. IBM claims that this data amount exceeds the entire daily Internet traffic. The amount would suffice to fill over 15 million 64 GB iPods.’


#big_data – Can Data Science predict Hit songs? Hey ya! They say you can ‘score’ your own song real soon. Insights –

  • Before the eighties, the danceability of a song was not very relevant to its hit potential. From then on, danceable songs were more likely to become a hit. Also the average danceability of all songs on the charts suddenly increased in the late seventies.
  • In the eighties slower musical styles (tempo 70-89 beats per minute), such as ballads, were more likely to become a hit.

Which is not to say that the person is a moron, but just that his understanding of the meaning of the word model is much more narrowly focused than mine.’

#analysis1) How they predict bugs at Google

‘Bug prediction uses machine-learning and statistical analysis to try to guess whether a piece of code is potentially buggy or not, usually within some confidence range. Source-based metrics that could be used for prediction are how many lines of code, how many dependencies are required and whether those dependencies are cyclic’

Evil data miners often specialized in “explaining” financial data, especially theUSstock market. Here’s a nice example: we often hear that the results of the Superbowl in January will predict whether the stock market will go up or down for that year. If the NFL wins, the market goes up, otherwise, it takes a dive.’
