I personalize my chat LLMs to avoid human-like speech and to sound as emotionless as possible. The answers are closer now to reading encyclopedia entries.

Except, I still respond "are you serious?" or "no, you idiot" when the answers are off.

We train machine learning models on millions of proteins. But when it comes to making predictions, do we need them to understand all proteins at once? Often, we need an accurate model for the specific protein we are studying or designing. We address this with ProteinTTT arxiv.org/abs/2411.02109 1/🧵

Funny thing, I don’t think my chatbot-boosted productivity is from working faster. It’s from working happier and being focused longer. It’s social interaction. And on the other side is a hyper enthusiastic junior that has been trained slightly wrong, as a joke. I won’t let you down buddy.

After trying all the premium chatbot models I can say that the sweet spot I’m comfortable with is about ~50 words max for writing as a superthesaurus and ~2-3 DSA at a time for refactoring. Generative writing is schlop and vibe coding is hit or miss at any length.

Baidu officially open-sourced its Ernie 4.5 large language model yesterday, marking one of China's biggest AI moves since DeepSeek shook global markets. The release includes 10 different models, ranging from 0.3B to 424B parameters, all available under the Apache License 2.0 for commercial use.

Just sharing this widget I threw together. It's been very helpful for visualizing the input data I've been throwing into a model of DNA systems that I've been working on. Data generated from NUPACK. github.com/dfu99/dna-co...

Claude's coding is suddenly horrible. It's been rewriting code artifacts, mixing the logic in each revision, and then offers a bunch of artifacts as variations, but they all only link to the most recently generated artifact.

Sam Gershman writes beautifully about how theory-free neuroscience prevents the field from reaching its promise. Beautiful and true. Most folks do not test hypotheses. Running a NHST does not a hypothesis make. www.thetransmitter.org/theoretical-...
Breaking the barrier between theorists and experimentalists
Many neuroscience students are steeped in an experiment-first style of thinking. Let’s not forget how theory can guide experiments.

💯. Most aspects of the system subtly (or not-so-subtly) push you back in your lane, making interdisciplinary work very hard.
Expert's Dilemma: the more specialized you become, the less open you are to creative solutions from other fields. But the more you explore other fields, the more you risk losing credibility in your home field.
Interdisciplinary work is still not really embraced by academia.

One main pain point: interdisciplinary work is often judged by the highest standards in *both* disciplines. This creates an almost impossible burden, effectively extinguishing creative work. Sure, some standards are there for a reason, but more often than not, they are just stock critiques.

I hate the direction lab equipment design has gone in recent years.

I don't want touchscreens, I don't want wifi integration, I don't want centrifuges demanding to know what time zone they're in.

I just want reliable instruments - with physical buttons - that do the one task they were made for.
