Norvig’s claim that programming competitions correlate negatively with being good on the job

Erik Bernhardsson

I saw a bunch of tweets over the weekend about Peter Norvig claiming there’s a negative correlation between being good at programming competitions and being good at the job. There were some decent Hacker News comments on it. Norvig’s statement is obviously not true if we’re drawing samples from the general population – most people can’t code.

Common Probability Distributions: The Data Scientist’s Crib Sheet

Data scientists have hundreds of probability distributions from which to choose. Where to start?

The applied mathematicians have their revenge, because statistics hasn’t been this talked-about since the roaring 20s.

Black Box Machine Learning in the Cloud

Erik Bernhardsson

There’s a bunch of companies working on machine learning as a service. Some old companies like Google , but now also Amazon and Microsoft. Then there’s a ton of startups: PredictionIO ($2.7M funding), BigML ($1.6M funding), Clarifai , etc, etc. Here’s a nice map from Bloomberg showing some of the landscape. As much as I love ML, I’m not super bullish on these companies. I wrote a pretty cynical tweet the other day.

Nearest neighbors and vector models – part 2 – algorithms and data structures

Erik Bernhardsson

This is a blog post rewritten from a presentation at NYC Machine Learning on Sep 17. It covers a library called Annoy that I have built that helps you do nearest neighbor queries in high dimensional spaces. In the first part , I went through some examples of why vector models are useful. In the second part I will be explaining the data structures and algorithms that Annoy uses to do approximate nearest neighbor queries. Let’s start by going back to our point set.

Benchmark of Approximate Nearest Neighbor libraries

Erik Bernhardsson

Annoy is a library written by me that supports fast approximate nearest neighbor queries. Say you have a high (1-1000) dimensional space with points in it, and you want to find the nearest neighbors to some point. Annoy gives you a way to do this very quickly. It could be points on a map, but also word vectors in a latent semantic representation or latent item vectors in collaborative filtering.

The relationship between commit size and commit message size

Wow I guess it was more than a year ago that I tweeted this. Crazy how time flies by. Anyway, here’s my rationale: When I update one line of code I feel like I have to put in a long explanation about its side effects, why it’s fully backwards compatible, and why it fixes some issue #xyz. When I refactor 500 lines of code, I get too lazy to write anything sensible, so I just put “refactoring FooBarController”. Note: don’t do at home!

How Many of Your Organization’s Strategic Initiatives Succeed?

My guess is that your answer is less than half or at least “not enough of them.”. Delivering on strategic initiatives on time, every time, is the hallmark of organizations that are best in the world at executing strategy, and they’re rewarded with a premium put on the value of their company. Organizations that can’t deliver on their strategic initiatives fail at executing their strategy, and organizations that fail at executing strategy will not survive. It is just that simple.
