The main
outcome of our analysis is that, for classification, the hinge loss appears
to be the loss of choice. Other things being equal, the hinge loss leads to
a convergence rate practically indistinguishable from the logistic loss rate
and much better than the square loss rate. Furthermore, if the hypothesis
space is sufficiently rich, the bounds obtained for the hinge loss are not
loosened by the thresholding stage.

How to process a million songs in 20 minutes « Music Machinery

How to process a million songs in 20 minutes « Music Machinery: "The recently released Million Song Dataset (MSD), a  collaborative project between The Echo Nest and Columbia’s LabROSA is a fantastic resource for music researchers. It contains detailed acoustic and contextual data for a million songs. However, getting started with the dataset can be a bit daunting. First of all, the dataset is huge (around 300 gb) which is more than most people want to download.  Second, it is such a big dataset that processing it in a traditional fashion, one track at a time, is going to take a long time.  Even if you can process a track in 100 milliseconds, it is still going to take over a day to process all of the tracks in the dataset.  Luckily there are some techniques such as Map/Reduce that make processing big data scalable over multiple CPUs.  In this post I shall describe how we can use Amazon’s Elastic Map Reduce to easily process the million song dataset."

fourteen years of pantone colors-of-the-year (tecznotes)

fourteen years of pantone colors-of-the-year (tecznotes): "2000: Cerulean Blue.

This color represents the millennium because of the calming zen state of mind it induces. Blue is known to be a calming color.
Leatrice Eiseman, executive director of the Pantone Color Institute®, said that looking at a blue sky brings a sense of peace and tranquility. “Surrounding yourself with Cerulean blue could bring on a certain peace because it reminds you of time spent outdoors, on a beach, near the water—associations with restful, peaceful, relaxing times. In addition, it makes the unknown a little less frightening because the sky, which is a presence in our lives every day, is a constant and is always there,” Eiseman said."
