Welcome to Moscow LW community makeshift games! In that games, some rationality skills are involved, so you can practise while you playing!

  • Fallacymania: it is a game where you guess logical fallacies in arguments, or practise using logical fallacies yourself (depending on team in which you will be).

  • Tower of Chaos: funny game with guessing the rules of human placement on a Twister mat.

  • Scientific Discovery: modified version of Zendo with simultaneous turns for all players.

It's been a while since we've reflected on questions like: What is this meetup for? What are we getting out of it, and what do we want to get out of it? How could we do better? What are new formats or topics we could try?

This meetup will be partly collection of feedback, partly brainstorming, and partly putting together concrete plans for the future. (And as usual, I expect there will be some casual conversations, too.) For help getting into the building, please call (or text, with a likely-somewhat-slower response rate): 301-458-0764.

Format:

We meet and start hanging out at 6:15, but don’t officially start doing the meetup topic until 6:45-7 to accommodate stragglers. Usually there is a food order that goes out before we start the meetup topic.

About these meetups:

The mission of the SF LessWrong meetup is to provide a fun, low-key social space with some structured interaction, where new and non-new community members can mingle and have interesting conversations. Everyone is welcome.

We explicitly encourage people to split off from the main conversation or diverge from the topic if that would be more fun for them (moving side conversations into a separate part of the space if appropriate). Meetup topics are here as a tool to facilitate fun interaction, and we certainly don’t want them to inhibit it.

WHERE: The Henley Club

Less Wrong Melbourne dojo, 16 July 2017

At the Henley Club in central CBD, Melbourne.

THIS MONTH:

The science of habit formation. Drawing on psychology research, and practical application inspired by the CFAR workshops and researcher BJ Fogg, we discuss how to break and create habits to achieve our goals.

As always, we may draw on the content in the Less Wrong Sequences and top books in relevant fields.

Facilitated by Adam Karlovsky.

BRING:

  • An inquiring mind, and observations you may have on the topic.
  • Perhaps a snack or drink to share. (Bonus points for healthy choices.)
  • Interested friends.

WHEN:

3:30pm to 6:30pm (and then optional dinner). Come early to catch up, and the meeting proper begins at 4pm sharp.

At about 6:30pm some of us generally head for dinner nearby, and you are welcome to join us.

WHERE:

The Henley Club Level 1, 8 Rankins Lane, Melbourne CBD https://goo.gl/maps/vmFL6JeKQSD2

It's down a lane (off Little Bourke, near Elizabeth) and one flight up a stairwell. If you have trouble, text or call Adam on 0412 064 542.

WHO ARE WE AND WHY DO WE MEET?

The Less Wrong Melbourne Rationality Dojos are a chance to polish your planning, motivational, critical thinking and other rationality skills. We welcome new members who are interested in exploring rationality. We're "aspiring rationalists" and always open to learn.

The paper is available here: https://arxiv.org/abs/1705.08417

This is a recent collaboration between DeepMind and Australian National University.

Abstract: << No real-world reward function is perfect. Sensory errors and software bugs may result in RL agents observing higher (or lower) rewards than they should. For example, a reinforcement learning agent may prefer states where a sensory error gives it the maximum reward, but where the true reward is actually small. We formalise this problem as a generalised Markov Decision Problem called Corrupt Reward MDP. Traditional RL methods fare poorly in CRMDPs, even under strong simplifying assumptions and when trying to compensate for the possibly corrupt rewards. Two ways around the problem are investigated. First, by giving the agent richer data, such as in inverse reinforcement learning and semi-supervised reinforcement learning, reward corruption stemming from systematic sensory errors may sometimes be completely managed. Second, by using randomisation to blunt the agent's optimisation, reward corruption can be partially managed under some assumptions. >>

Also see Tom's blog post about this paper here: http://www.tomeveritt.se/paper/2017/05/29/reinforcement-learning-with-corrupted-reward-channel.html

Please do your best to read the paper in advance, so we can have a good discussion about the content.

If necessary, David Krueger will give a run-down of the paper.

Find us on level 2 outside the pizza oven. For this month bring along a suggestion of a book you want more people to read. Come along to our regular monthly pub meetup to talk all things math, science, technology, engineering, thinking, growth, reasoning and beliefs. If you are an aspiring rationalist, a nerd, geek, scientist or just a quiet thinker - we can't wait to meet you to share ideas, discuss, debate, learn and grow together. If you are interested in our rationality dojos, ask us about them in person. See you there! Also, while you are at it - bring a friend along too! We usually get ~15 attendees through various advertising avenues.
