Super Intelligence for The Stock Market

Numerai is synthesizing machine intelligence to command the capital of an American hedge fund using crowdsourcing and ensembles. This is interesting stuff—I don’t feel qualified to have an opinion on whether it’s as big as they claim, but you definitely need to read this. Here are two more great posts from the team if you’re a finance data geek.

A Concise History of Neural Networks

If you’re anything like me, you know that deep learning isn’t a new concept, that it has its roots many decades ago. You’re probably familiar with the name Marvin Minsky, and you know that today’s breakthroughs rely on these theoretical breakthroughs from the past. This article fills in the gaps, giving you a primer on the history of what may be the most important technology of our time. And it’s only a six-minute read. Do yourself a favor: read it.

100 Billion Records Later, Refining our ETL Service

This post, written by the VP Engineering at Stitch, goes deep into the challenges faced in building a data pipeline that has delivered 100 billion records over its first 10 months. My personal takeaway: data engineers may sometimes be too quick to incorporate open source tools. The Stitch team has now removed Spark from their stack and reduced its usage of Kafka. Very interesting lessons that may save you thousands of engineering hours.

Internet Tracking Has Moved Beyond Cookies

Much of the source data for data science comes from user clickstream data. And the key to the entire clickstream is the cookie: a clever hack invented in the 90’s. But in the ad tech industry, cookies are gradually being shunted in favor of fingerprinting. Read this article if you do (or plan to do) any work with clickstream data.
