Phil 7.8.18

Scott Klemmer Keynote 2

  • What are interesting things that we can do with computers and teaching – 2011
  • Objective truth <-> Contextual truth
  • Design is in the middle, between objective and subjective truth
  • The act of assessing work is a good way to improve understanding
  • Problem finding as opposed to problem solving
  • “A negotiation around the valuation criteria” Jeff Nicholson
  • Negotiations also happen between the creators and the users, particularly in software design. The initial design is the starting point of that journey
  • What counts as preferred shifts over time
  • Talkabout – The subway model. Pick a time that you’re going to show up, and we’ll put you in a group. Small groups discuss topics.
  • Assigning to globally diverse discussion groups increase grades by greater amounts than more local, less diverse groups. Open-ended questions
  • DSCN0348DSCN0349DSCN0350DSCN0351DSCN0352

Participated in the panel on innovation in crowds (invited). There is a video, so I can figure out who to add:

  • Christopher Tucci,
  • Gianluigi Viscusi (GG)
  • Rosy Mondardini
  • Thomas Malone
  • Joel Chan
  • Philip Feldman

Eszter Hargitti – U of Zurich

  • Awareness of what is possible
  • The ability to create and share content
  • Wikigroan?
  • DSCN0353DSCN0354DSCN0355

When Ties Bind And When Ties Divide: The Effects Of Communication Networks On Group Processes And Performance DSCN0356.JPG_1DSCN0357.JPG_2

  • Network structural variance

Enhancing Collective Intelligence of Human-Machine Teams DSCN0358DSCN0359

  • Cognitive and ethnic diversity predict collective intelligence
  • Group structure, high level communication and equality of communication
  • It’s the quality of the individuals and the quality of the connections
  • Coordination technologies – connect humans

Implicit Coordination in Peer Production Networks DSCN0360DSCN0361DSCN0362DSCN0363

Collective Intelligence Systems for Analogical Search (must read! Joel Chan is at UMD)

  • Really interesting, worth reading. Purpose and mechanism may be related to belief spaces. Definitely trainable using NN to find purpose mechanism

Rational Collective Learning in the Laboratory

  • Groupthink. as a failure of design
  • Randomy constructed groups can make good design choices given failing parts with a history.

8:00 – 9:00 ASRC MKT

  • At CI 2018. Hell of a time setting up eduroam. Nice venue, though. Winston Churchill called for the unification of Europe from that podium. Probably without PowerPoint DSCN0310
  • Patrick Meier – keynote – Digital humanitarian efforts
    • Mission is to pioneer the next generation of humanitarian technology
    • DSCN0313
    • DSCN0315
  • Poster pitches
    • Multiple barriers to crowdsourcing, ranging from operational to strategic
    • Anita Wollie – trust in AI Embedded agency, Virtual agency, Physical Agency
    • Croudoscope – qualitative and quantitative surveys – open coments. Not lists, but graphs
    • Market volitility with High-Frequency trading an hmans
    • How many people constitutes a ‘crowd’
    • Is novelty an advantage in crowdfunding
    • QUEST – annotating questions on stackoverflow-style probles’
    • Cyber-physical systems – e.g. smart transportation systems
  • Papers
  • Keynote 2
    • Optimizing the Human-Machine Partnership with Zooniverse DSCN0321 DSCN0322
      • Lucy Fortson
      • Galaxy Zoo
      • Zooniverse is on its third iteration and now supports project building
      • Can also point to a project
  • Session 2
    • Collective Intelligence for Deep Reinforcement Learning (MIT, mostly)
      • Evolutionary strategies (Salimans 2017) DSCN0327
    • Social learning strategies for matters of taste (This is a must-read!)
      • DSCN0326DSCN0325DSCN0324
    • Photo Sleuth: Combining Collective Intelligence and Computer Vision to
      Identify Historical Portraits

      • Good discussion of how to blend human and ML person identification
    • Toward Safer Crowdsourced Content Moderation
    • How Intermittent Breaks in Interaction Improve Collective

Phil 7.1.18

On vacation, but oddly enough, I’m back on my morning schedule, so here I am in Bormio, Italy at 4:30 am.

I forgot my HDMI adaptor for the laptop. Need to order one and have it delivered to Zurich – Hmmm. Can’t seem to get it delivered from Amazon to a hotel. Will have to buy in Zurich

Need to add Gamerfate to the lit review timeline to show where I started to get interested in the problem – tried it but didn’t like it. I’d have to redo the timeline and I’m not sure I have the excel file

Add vacation pictures to slides – done!

Some random thoughts

  • When using the belief space example of the table, note that if we sum up all the discussions about tables, we would be able to build a pretty god map of what matters to people with regards to tables
  • Manifold learning is what intelligent systems do as a way of determining relationships between things (see curse of dimensionality). As groups of individuals, we need to coordinate our manifold learning activities so that we can us the power of group cognition. When looking at how manifold learning schemes like t-sne and particularly embedding systems such as word2vec create their own unique embeddings, it becomes clear that our machines are not yet engaged in group cognition, except in the simplest way of re-using trained networks and copied hyperparameters. This is very prone to stampedes
  • In conversation at dinner, Mike M mentioned that he’d like a language app that is able to indicate the centrality of a term an order that list so that it’s possible to learn a language in a “prioritized” way that can be context-dependent. I think that LMN with a few tweaks could do that.

Continuing the Evolution of Cooperation. A thing that strikes me is that once a TIT FOR TAT successfully takes over, then it becomes computationally easier to ALWAYS COOPERATE. That could evolve to become dominant and be completely vulnerable to ALWAYS DEFECT
