Social Media Demographics for Marketers in 2020

We get it, fellow marketers —sometimes, you just need the numbers. 
The new year means a lot of things: new life changes, new opportunities, chances to change lives, and, for marketers, new campaigns to plan. 
The juggernaut known as social media only gets bigger with every new year, and because of that, demographics shift with it.

Formatting numbers at the command line

The utility numfmt, part of Gnu Coreutils, formats numbers. The main uses are grouping digits and converting to and from unit suffixes like k for kilo and M for mega. This is somewhat useful for individual invocations, but like most command line utilities, the real value is using it as part of pipeline.
The –grouping option will separate digits according to the rules of your locale.

Four years ago (more or less) — something to remember when reading the latest analysis from Nate Cohn (and a lot of others)

Track records matter. Like it or not, unless you’re actually working with the numbers, you have to rely to some degree on the credibility of the analysts you’re reading. Three of the best ways to build credibility are:1. Be right a lot.2. When you’re wrong, admit it and seriously examine where you went off track, then…3. Correct those mistakes.

Statistical Self-Defense

No day without numbers in (social) media, in everyday life. And they not only want to inform us, they also want to orient us in one direction or the other.
And every day are among them deliberately or unintentionally false or misleading numbers.
Therefore, statistics must arm themselves against incorrect use of data and repeatedly teach the correct handling of statistical data.

How much compute do we need to train generative models?

Update (09/01/17): The post is written to be somewhat silly and numbers are not meant to be accurate. For example, there is a simplifying assumption that training time scales linearly with the # of bits to encode the output; and 5000 is chosen arbitrarily given only that the output’s range has 65K*3 dimensions and each takes one of 256 integers.
Discriminative models can take weeks to train.

Jesse or Celine? Text Classification on Before Sunrise Dialog: Part II

In the last article, we converted movie dialog into numbers using a bag-of-words approach. Here we go in another direction and use an embedding model to represent text in a dense manner. So instead of capturing stylistic tendencies of Jesse and Celine (via word choice in a bag-of-words model), we will try to capture the semantic differences between their words (via an embedding model).

Dissecting Diophantine Equations

The word Diophantine refers to Diophantus, the third century mathematician from Alexandria. Numbers are the fundamental building blocks of mathematics, so he started thinking about problems for which we need integer solutions. For example, how many horses do we need to achieve a particular task? Even if the exact answer is 15.5, we cannot really cut the last horse into half.

Understanding Catalan’s Conjecture

Numbers are deceptively simple. We use them everyday in a variety of contexts. It’s beautiful how there are so many mysteries hidden inside these numbers. Catalan’s Conjecture is a mathematical problem that’s really easy to understand, but extremely difficult to prove. In fact, it took around 158 years to come up with a mathematical proof.
