Continuing the succession of immensely successful dojos, Gus will run a session on Introduction to Ethics.

As always, we will review the personal goals we committed to at the previous Dojo (I will have done X by the next Dojo). Our goals are now being recorded via Google Forms here -https://docs.google.com/forms/d/1MCHH4MpbW0SI_2JyMSDlKnnGP4A0qxojQEZoMZIdopk/viewform, and Melbourne Less Wrong organisers have access to the form results if you wish to review the goals you set last month.

This month, we are also seeking 2-3 lightning talks from members. Have you learned something cool? Gained an insight from one of the Less Wrong sequences? Give a lightning talk and share it with Melbourne LW! Speakers will be limited to 5 minutes with room for questions. If you have something you would like to present a lightning talk on, please contact Louise with your topic at lvalmoria@gmail.com or talk to Richard on the day.

The Dojo is likely to run for 2-3 hours, after which some people will get dinner together.

The Role of Attractiveness in Mate Selection: Individual Variation

13 JonahSinick 23 January 2015 11:21AM

This post reports on a portion of my analysis of Fisman and Iyengar's speed dating dataset which bears on the question of how people select romantic partners. 


Note:
 I made very substantial edits to the second to last section of this post having posted it, addressing questions of generalizabilityI've also cross-posted to my blog.

Summary

  • Participants rated one another on several dimensions. The majority of variation in the ratings is captured by the average of the different rating types: some people were regarded as good overall, and others were regarded as not good overall.
  • The second most important source of variation in the ratings given to participants is that some were regarded as more attractive and fun than they were intelligent/sincere, and for others, the situation was reversed. 
  • Broadly, when people had to chose between partners who were seen as attractive and fun and partners who were seen as intelligent and sincere, they had a moderately strong preference for partners who were seen as attractive and fun.
  • Individuals varied substantially in how they responded to the tradeoff, with some showing very strong preference for people who were seen as attractive and fun people, and others showed virtually no such preference.

 

The speed dating context may be unusual in that people make a decision on whether or not to see somebody again after only 4 minutes of interaction. On the other hand, some people do meet their partners in contexts such as bars and speed dating events where decisions are made based on brief interactions. To this extent, the empirical phenomena in data from the study are relevant to understanding mate selection in general.

Formalizing Two Problems of Realistic World Models

14 So8res 22 January 2015 11:12PM

I'm pleased to announce a new paper from MIRI: Formalizing Two Problems of Realistic World Models.

Abstract:

An intelligent agent embedded within the real world must reason about an environment which is larger than the agent, and learn how to achieve goals in that environment. We discuss attempts to formalize two problems: one of induction, where an agent must use sensory data to infer a universe which embeds (and computes) the agent, and one of interaction, where an agent must learn to achieve complex goals in the universe. We review related problems formalized by Solomonoff and Hutter, and explore challenges that arise when attempting to formalize analogous problems in a setting where the agent is embedded within the environment.

This is the fifth of six papers discussing active research topics that we've been looking into at MIRI. It discusses a few difficulties that arise when attempting to formalize problems of induction and evaluation in settings where an agent is attempting to learn about (and act upon) a universe from within. These problems have been much discussed on LessWrong; for further reading, see the links below. This paper is intended to better introduce the topic, and motivate it as relevant to FAI research.

  1. Intelligence Metrics with Naturalized Induction using UDT
  2. Building Phenomenological Bridges
  3. Failures of an Embodied AIXI
  4. The Naturalized Induction wiki page

The (rather short) introduction to the paper is reproduced below.

Meetup : Czech's first Meetup Prague

WHEN: 16 February 2015 06:00:00PM (+0100)

WHERE: Václavské náměstí 778/14, Praha 110 00

Hello, this is going to be the first meetup I know about in Czech Republic. Since I don't know any other LessWrongers here, I'll be waiting in Dobrá Čajovna s.r.o. (tea-room) for at least one hour. Look for 22-year-old, tall, skinny, brown curly haired guy.

Please contact me if you are interested in a meeting, but the time just doesn't fit you - it will be at least some sign for me that someone is at least interested.

Feel free to ask if you have any questions.

I decided to try to make a meetup from time to time (this is the second try) to see if someone will ever show up. It's a pity (and shame) that there are no meetups here. My goal is to estabilish regular meetings of stable core of LessWrongers.

Control Theory Commentary

9 Vaniver 22 January 2015 05:31AM

This is the third and final post in a sequence on control theory. In the first post I introduced the subject of control theory and stepped through some basics. In the second post I outlined Powers's model, as presented in Behavior: The Control of Perception. This post is a collection of comments on the subject that are only somewhat related, and so I'll use section headings to separate them. I'll also explicitly note the absence of a section on the design of control systems, which is where most of the effort used in talking about them in industrial settings goes, and is probably relevant to philosophical discussions surrounding them.
