With our v1.0 release, dream-stream now comes in Android 🤖!

context-lab.com/dream-stream...

I made a quirky little web app to help guide your lucid dreams: context-lab.com/dream-stream/

It's kind of like a "netflix" or "spotify" for lucid dreaming-- you select different narratives to form a playlist, and then it uses your device's microphone to start playing when it detects you're in REM.

Excited to be teaching a new undergraduate course on Models of Language and Conversation this term!

I've added lots of fun interactive demos of chatbots and NLP techniques that let students dig into the approaches.

Remember when grinding leetcode was still a thing? If you'd like to hone your coding skills, or even just return to that simpler time for nostalgia's sake, you might enjoy this project from our group: github.com/ContextLab/l...

Happy hacking! 👩‍💻

🚨 New preprint alert!

We use trained-from-scratch GPT-2 models to characterize & capture the unique writing styles of individual authors. We also develop a new LLM-based relative stylometric measure.

🤠 New release announcement for our datawrangler package! Try it using:

pip install --upgrade pydata-wrangler

Lots of awesome performance improvements (including native polars support!), simplified API, support for @hf.co text embeddings, etc. More info here: data-wrangler.readthedocs.org

We're super excited to announce that we've officially convinced @cgonciulea.bsky.social to join our rag-tag (but VERY classy) team of science nerds this fall as a @dartmouthpbs.bsky.social PhD student 🎉🥳🤓🧠🧑‍🔬🎓!!

Just finished a draft of my Models of Memory (grad) course that I'm teaching this spring! Please share/borrow/re-use/follow along as desired, and if you have feedback or suggestions I'd really love to hear (especially while I can still change it)!

All materials are here: github.com/ContextLab/m...

Re-sharing from Xitter-- new paper out in @pnas.org (lead: Lucy Owen)!

We show how the informativeness and compressibility of brain activity patterns change under different levels of cognitive engagement: www.pnas.org/doi/10.1073/...

Lots of neat stuff in there!

Excited to have this out in @natureportfolio.bsky.social!

We found that real & fictional people communicate roughly 1.5x more about the past than the future.

In turn, this influences the interferences we make about past & future events in *other* people's lives.

Imagine Google Colab notebooks that support:
✔️ Automatic dependency installs
✔️ Pinned package versions
✔️ Ability to download/run locally without additional setup

"pip install davos" today!

🚨 Updated preprint (lead: @xxming.bsky.social) on how inferences about unobserved past/future events are informed by conversations! osf.io/yp2qu/ 🚨

This update includes a new pre-registered replication + meta analysis. We think we've found some neat fundamental properties of human conversation!

🧪🧠

📣: Just updated our "modeling Khan Academy learning" preprint (lead: @paxt0n4.bsky.social)!

We're excited about this revision and grateful to our reviewers-- lots of neat new analyses using text embeddings to show how knowledge changes over time + conceptual content.

Link: osf.io/preprints/ps...

This release adds an awesome (automated!) system for managing notebook dependencies that's isolated from the runtime environment.

Importing Davos into your notebook makes your notebook a "fully enclosed" + shareable doc (w/ code/figures/data/text) that installs its own dependencies!

Check it out!

Excited to announce the latest release of our "Davos" #python package (v0.2.3)! 🎉🥳

Add Davos to a Jupyter notebook by:
- inserting a new cell with this code at the top:

%pip install davos
import davos

- replacing all uses of "import" with "smuggle"

Hello blue sky! Our lab studies #learning & #memory. We do roughly 50% cog sci style studies and 50% brain networky things, with some overlap where possible. Lately we've been excited about real-world memory in classrooms and conversations. We'll use this account to share our papers/software!
