COIN Seminar · Fall 2026

HiddenSignals

Reading the honest signals of every living thing — with AI.

A plant has no face and no voice. But voltage runs through its leaves, and it changes when you touch it, when the light shifts, when you come near. This seminar teaches you to read that language — and the honest signals of humans, animals, and crowds — with machine learning you build yourself.

01 · The Frontier

Everyone talks about flying to Mars. The real unexplored frontier is right beneath our feet.

Mars is escape — the idea that if we ruin this planet we start over somewhere else. Learning to read the other living things that share it is the opposite: integration, learning to live as part of Earth's system rather than its exploiter.

This isn't science fiction. Cheap sensors, fast models, and the same machine-learning trick that cracked image recognition now let us reach signals that were always there and never readable — a face's micro-expressions, a cat's call above our hearing, the voltage in a leaf. AI here is a new sense organ.

You'll work with real research data and, in the best case, contribute to publications. No prior deep-learning experience is required. The path is deliberately scaffolded: everyone reaches a working result, and there's a steeper track for those who want it.

The course text — Hidden Signals: From Paracelsus to Plant Sensors — carries the whole arc, from a rebel physician who burned his textbooks to a mathematician who read the future of a crowd.

Humans

Face · Voice · Text

Emotion and stress read from expression, tone, and the rhythm of give-and-take.

Animals

Calls · Posture

Cat calls, dog and horse emotion — a language never meant as language.

Plants

Bioelectric

Leaf voltage that answers to touch, sound, light — and human presence.

Crowds

The Swarm

Collective mood from millions of messages, laid against events and markets.

01.1 · Four Visionaries

Four dreamers across five centuries — who imagined reading a hidden layer of the world before the tools existed.

1527

Paracelsus

The Physician

Read nature directly, not the old books. Every body wears its inner state as a signature.

1614

The Rosicrucians

The Invisible College

Knowledge shared freely across borders — the seed of open science, Wikipedia, open source.

1951

Isaac Asimov

Psychohistory

You can't predict one person. A crowd of millions bends into a smooth, readable curve.

1979

Douglas Adams

The Babelfish

Perfect understanding across every species. Could a machine be that translator?

02 · Creating COINs — the team method

The best ideas don't come from the single head. They come from between the heads.

You'll form Collaborative Innovation Networks — small, self-organizing teams built on 20+ years of research into how real innovation happens, from Linux to Wikipedia to the Transformer behind ChatGPT.

The finding, in one line from our study of sixteen medical online communities: it is rotating leaders who build the swarm. Teams grew when leadership moved from person to person, when there were clear connectors, and when people wrote simply.

And we practice what we measure. We use AI to analyze your team's own communication — who answers whom, who connects, whether one voice pulls everything toward itself — and mirror it back to you.

That mirror alone changes teams. Groups shown how they collaborate become more open and attentive; in a two-year field study, their customer satisfaction measurably rose. Measurement here isn't surveillance — it's an invitation to self-knowledge.

→ signals

Six honest signals

Rotating leadership, fast responsiveness, balanced contribution, honest sentiment, strong connectors, shared attention — measured for a whole team, not just one person.

→ tools

SocialCompass

Draw the living network of a group from its communication patterns and watch it change over time — the same map, in motion.

→ groupflow

Reaching groupflow

The state where a team clicks. You'll learn to recognize it, measure it, and steer your own team toward it across the term.

03 · Projects

Every activity in the book runs on two tracks. No one drowns; no one coasts.

Base track

Everyone gets a working result

Hands-on, scaffolded, guided step by step. You finish with something that runs.

  • Build the Biolingo plant sensor and see the first voltage curve
  • Classify cat calls with a small two-stage audio model
  • Find the "queen bee" in an open-source community (networkx)
  • Read the swarm's mood from social-media data over time
Master track

A steeper climb for those who want it

Deeper methods, real research questions, publication potential.

  • Predict personality & values from facial reactions — and probe the limits
  • Fine-tune a mini language model into your own digital twin
  • Full spectral analysis of heart-rate → plant coupling
  • Lay collective sentiment against markets and elections
Plants

Plant emotion classifier

Turn a leaf's signal into a spectrogram and let a model read touch, light, and nearby human mood.

Networks

Reading an invisible college

Map who connects whom in a real open-source project — centrality, rotating leaders, the hidden hubs.

Animals

The Babelfish for pets

Emotion from a dog's or horse's posture; compare the model's guess with your own read.

Crowds

Asimov's psychohistory

Does the collective mood of a swarm forecast tomorrow's market or vote? Test it.

Teams

Collaboration booster

Diarize and analyze a real team meeting; mirror its network back and measure the change.

Digital twin

A model of a person

The boldest activity — and the sharpest ethical edge. Build one, then argue its limits.

// These are starting points. Teams propose and shape their own projects.

04.1 · Pre-work

Before you join a team, you do the reading — and you run the tools on yourself.

To join, contact the local administrator at your university before the start date. Work through Hidden Signals: From Paracelsus to Plant Sensors to get familiar with the concepts, tools, and research questions, then complete the five steps below and present your results at the block course. You can join any project on the Projects page.

→ Complete all five steps before the block course (14.10). Steps 1–5 take roughly 60–90 minutes in total.

1

Read the book & sign up for a chapter

Read Hidden Signals, then claim one chapter in the shared sign-up sheet. Teams are two students (a few chapters need three, flagged in the sheet); first come, first served. Your team presents and leads discussion on that chapter at the block course — you're the resident experts on it.

2

Run the Symbiont Analyzer — now in Beecome

WhatsApp — the Symbiont Analyzer is now built into Beecome. Export a group chat you're active in (Menu → More → Export chat, without media) and load it in the app. You get a mix of the five collaboration archetypes — Bee, Ant, Butterfly, Capybara, Leech — plus the word patterns behind it. Note yours, and come ready to say whether it fits.

3

Run Perceptiface

On-phone · interactive — no upload. The app plays a short video while your front camera reads your micro-expressions, and returns your dominant emotion and a predicted Big Five profile. Note your result and one thing that surprised you.

4

Play the Beecome game

On-phone · interactive — no questionnaire. Swipe through a branching story; the model infers your Big Five from your choices. Compare it with your Perceptiface result — where do the two models agree, where do they diverge?

5

Enter your results in the shared spreadsheet

One row per student. Fill in each tool's output — archetype and percentage, the labels and personality profiles, your dominant emotion — and leave blank whatever a tool didn't show.

At the block course — present & facilitate

Each team gets a 30-minute slot
15 min · present

The argument, not a summary

Identify your chapter's single most important claim, its strongest evidence, and where it meets the seminar's themes — honest signals and swarm creativity. Empirical chapters need at least one slide on the method or data.

15 min · facilitate

You lead the room

Prepare exactly three discussion questions:

  • Clarify — something genuinely ambiguous the class resolves together
  • Challenge — a claim you find weak. Push back.
  • Connect — a link outside the book: an event, a tool result, a team dynamic you've lived

"Here is what the tool said about us. Here is what the chapter predicts it should say. Here is where they disagree — and that disagreement is our discussion question."

05 · Team

Frontier research. Nobody has all the answers — that's the point.
