Yes, you succinctly made the same argument I was trying to make. I think Kaggle is pushing the industry to be more efficient, but in an ironically inefficient way.

Kaggle is a great idea; I actually entered the industry partly through a data mining contest (pre-kaggle). But I think the article overstates Kaggle's influence on industry, at least at this point in time. >the Kaggle ranking has become

Yep, thanks. I clearly don't know much about bitcoins :| In retrospect that makes a lot of sense with bitcoins going for ~200 USD each.

I don't understand the point of the '0-1' option because it completely overlaps with other options. But it's one of the most popular choices so far with 17 votes.

Is there actually any evidence that people get removed from flights more nowadays? With 100s of millions of domestic people-flights a year we're bound to see a small number of absurd events, like airline employees in a bad mood (not uncommo

I agree with you about questionable design choices, I really don't like developing in R. But if you have some data and you want to know more about that data (data analysis), R + a small handful of packages is the best free environment that

For me (in the data world) perl works really well within the unix philosophy. Basically my perl programs are small, simple, reusable, and can be piped together. My typical perl program is less than 200 lines and works on standard input/outp

I think this is actually quite different from random projection, which creates linear combinations of several continuous variables. RP is much more similar to PCA in that respect. OP's method works on a single categorical variable and essen

This is pretty similar to the approach that many predictive modelers already use: compress data down into 'dummy variables', where each variable represents some attribute. For example, you could convert the variable state into 51 dummy vari

Wow, that's an absurdly misleading headline. Here's the editor's analysis: http://en.wikipedia.org/wiki/User:Colin/Introduction_to_Psyc... I see 16 cited cases of supposed plagiarism. How did we go from 16 cases to claiming 85% of people

My issue with both this and the post it's replying to is the underlying sense of entitlement. The "who is hiring process" is great for reducing friction in matching good employers with good employees. All the pride (in the deadly sin way) I

Great point, I'll have to reevaluate how I use R. My training in R was very informal and mostly involved reading other people's code, so my "vocabulary" is probably a union of other peoples' and is probably too large. Actually one thing tha

A large pain point for me is remembering the huge number of useful commands in R - I use at least 5-10x as many keywords in R as I did in C++. As I mention in another comment I basically need a reference (usually google and ?) at all times

As the article discusses, R has a steep learning curve. Mastering R requires knowing dozens of commands and tricks, but once you learn those the language becomes very expressive and quick to work with. I agree it's frustrating. I've been wo

At this point, mostly library support. Python is quickly getting closer to being a viable R replacement, but it's simply not there yet IMO. The two biggest holes in python for me are: * The lack of built-in dataframes and libraries to work
