Kalman filter - Wikipedia
Kalman filtering, also known as linear quadratic estimation (LQE), is an algorithm that uses a series of measurements observed over time, containing statistical noise and other inaccuracies, and produces estimates of unknown variables that tend to be more accurate than those based on a single measurement alone

‘I made Steve Bannon’s psychological warfare tool’: meet the data war whistleblower | News | The Guardian
Its expertise was in “psychological operations” – or psyops – changing people’s minds not through persuasion but through “informational dominance”, a set of techniques that includes rumour, disinformation and fake news.

He believes in the whole Andrew Breitbart doctrine that politics is downstream from culture, so to change politics you need to change culture. And fashion trends are a useful proxy for that. Trump is like a pair of Uggs, or Crocs, basically. So how do you get from people thinking ‘Ugh. Totally ugly’ to the moment when everyone is wearing them? That was the inflection point he was looking for.”

a new kind of political message-targeting based on an influential and groundbreaking 2014 paper researched at Cambridge’s Psychometrics Centre, called: “Computer-based personality judgments are more accurate than those made by humans”.

How Cambridge Analytica turned Facebook ‘likes’ into a lucrative political tool | Technology | The Guardian
When users liked “curly fries” and Sephora cosmetics, this was said to give clues to intelligence; Hello Kitty likes indicated political views; “Being confused after waking up from naps” was linked to sexuality.

“Commercial companies, governmental institutions, or even your Facebook friends could use software to infer attributes such as intelligence, sexual orientation or political views that an individual may not have intended to share.”

Within months, Kogan and Cambridge Analytica had a database of millions of US voters that had its own algorithm to scan them, identifying likely political persuasions and personality traits. They could then decide who to target and craft their messages that was likely to appeal to them for those individuals – a political approach known as “micro-targeting”.

IDEA – nonverbal algorithm assembly instructions
IDEA is a series of nonverbal algorithm assembly instructions by Sándor P. Fekete, Sebastian Morr, and Sebastian Stiller. They were originally created for Sándor's algorithms and datastructures lecture at TU Braunschweig, but we hope they will be useful in all sorts of context. We publish them here so that they can be used by teachers, students, and curious people alike. Visit the about page to learn more.
