"Decoding EEG for optimizing naturalistic memory" out now in Journal of Neuroscience Methods!! @ELSneuroscience TLDR; we trained neural decoders to predict memory success, then applied them to present items when people were predicted to learn well doi.org/10.1016/j.jneu…

I've plotted the most expensive McDonald's burger and the least expensive MacBook over time. This analysis projects that the most expensive burger will be more expensive than the cheapest laptop as soon as 2081

@_helenqu awesome blog name :)

like i mentioned, i plan to use this substack for higher-level, less technical thoughts about how i want to live my life, the role of career/relationships in my life, etc. yes, the irony of the fact that i titled my first post "value function learning" is not lost on me 2/3

ok yall i also started a substack 🤭 i wanted my more personal writing to live somewhere separate from my technical blog. my first post is a retrospective on 2025 and how i might finally be figuring out the value function for my life/career: open.substack.com/pub/sphericalc… 1/3

amazingly apt description of AI use for technical problems

Of course I follow lots of academic thought leaders and read technical papers too, which help a ton and give me context for understanding and filtering the above. I wonder A) if the above are understandable without said context and B) if so, how sufficient they are

I think you can get a surprisingly solid intuition for the current state of AI by following @karpathy, Yann Lecun, and @dwarkesh_sp podcast. Super high SNR relative to most stuff on twitter / LinkedIn, which are dominated by grifters and people hyping specific labs.

Easy to forget how much hidden prompt engineering is wrapped up in frontier LLM's... until your requests create a conflict 😅

@yihaoli_0302 awesome Yihao!!!

🧵[1/8] Excited to share our NeurIPS 2025 Spotlight paper “Does Object Binding Naturally Emerge in Large Pretrained Vision Transformers?” ✨ To add to the broader discussion of binding in neural networks, we ask whether and how Vision Transformers perform object binding (the ability to bind an object’s many features together as a coherent whole).💡 📄 Paper: openreview.net/pdf?id=5BS6gBb…

I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far).

Frontier models are still so weird in how sycophantic and overly-validating they are... Gemini 3 seems quite good from my usage so far, but it just began a response a technical question with "You are asking exactly the right questions for a PhD student" ...thanks...?

This is the single most massive factual error in a major book I've ever personally noticed on my own, and I think I'm the first person to notice it? Empire of AI asserts that a data center is using 1000x as much water as a city. In reality, it's 22% of the city's water.

✨ It’s hard to write an abstract. It’s harder to write a glamorous one that tells your story without overselling your results. 🛠️ Join us on Tuesday, December 2 @ 12 pm ET for a live abstract-writing workshop led by our P.I., Konrad Kording @koerding

In Philly, Philabundance is known for doing awesome work to fight food insecurity. philabundance.org If you have a PennKey you can double your donation by donating through the Penn's Way platform.

With the government shutdown threatening SNAP and other benefits, reminder to academics to check if your university will match donations to food pantries and the like! e.g. @Penn is currently doubling donations to local charities through: pennsway.upenn.edu #OurWayPennsWay

Thrilled to spend the next 4 months visiting @nadavcohen and the Foundations of Deep Learning group at Tel Aviv University. Extra grateful to witness today’s joyful return of the Israeli hostages captured on 10/7 and what is hopefully the start of enduring peace

We had a better season than the Mets at least

crazy that they called it context window when attention span was right there

@RyanBrill_ Congrats Ryan!! My sports analytics 🐐 Jazz stock 📈

Finally graduated after 5 wonderful years at Penn & excited to share that next week I begin as a Basketball Data Scientist w/ Utah Jazz! Grateful to the Penn community & broader sports analytics world for cultivating such an amazing & friendly space to continually learn & work:

baseball is pretty hard. go phils

dad asked how i was, told him my training run was crash looping, he said "have you tried turning it on and off again," i laughed and said haha dad i'm a serious engineer i don't do that, i hung up, did that, and it fixed the problem
