I used to build fraud models where we had insane amounts of negative data and precious positive data. Our performance metric was well-reasoned; as you mention, we cared about the happiness of our customer, and baked all sorts of useful info

I realize the point, I think it's the wrong way to lose weight (and I say this as someone who lost considerable weight and has kept it off for more than ten years). Counting calories temporarily tells someone how much he is overeating, but

How do you know what range of calories to target? Or that the labels are correct? How many calories are in the burger from that food truck? That the calories you are eating are healthy? I agree with you that it's good to know roughly how ma

Good article on why counting calories precisely is pointless and misleading. Another factor is that food labels are often incorrect - the FDA allows them to be up to 20% off in the USA. Even if you could figure out how many calories you con

It's up to them to prove you did anything wrong, which they won't be able to. The RIAA only targets people who illegally distribute digital media (something they can prove).

Well, that's why I said "take" on it. These companies are actually doing quite a bit that a traditional label would do: they store the media (the digital version of manufacturing it), distribute it, and market it. I don't think a traditiona

Spotify already lets unsigned artists add their music through music aggregators like cdbaby: http://www.spotify.com/us/work-with-us/labels-and-artists/ar... I suppose the music aggregators are a modern day take on record labels.

It's not about small tweaks, it can be substantial additions to a model that improve its actual, out-of-sample performance. A popular method in these contests is ensembling, which involves building many sub-models and combining their scores

You're right, the article argues that copying doesn't stifle innovation, but it goes beyond this and argues companies innovate because they are being copied. For example, this quote argues a correlation between copying and innovation, and h

Pretty cool, something simple like this built-in to phones would be great. If your friend knows much about the iphone he can go to the maps app and "share location" with you via text or e-mail. Is there something similar in Android?

by rm999 14y ago
I don't think the article rigorously defends its position. Just because a company innovates after being copied does not mean it is innovating because it was copied. The article doesn't give one example of a situation where a company was mot
