The Ledger

Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.

clear all ✕

why aren't all 7 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable

Rumbelow: Leap Labs' Discovery Engine Automates Novel Scientific Discovery via Interpretability
“Discovery Engine is an end-to-end system, takes in arbitrary scientific data set, automatically trains a bunch of neural networks on it, and then We systematically, with our interpretability methods, which is the real secret extract the patterns that have been…”

Rumbelow: Standalone Claude Opus Hallucinated Materials Science Data Findings
“So, so Claude, lovely Claude. I'm sorry Claude, but you did a terrible job. It hallucinated some stuff. It made some like big sweeping over, over generalizations. It like over indexed the few outliers. Like, it's fine. It's not Claude's fault. Like Claude is j…”

Rumbelow: Multimodal analysis is impossible without fine labeling or interpretability
“It's largely impossible to do good data analysis on multimodal data of this kind, unless you have really fine grained labeling of your images. For example, which is just very, very burdensome, but obviously deep learning, we can let the model figure out its ow…”

Rumbelow: Leap Labs Found Soil Manganese and Genotype Synergy Impacting Root Architecture
“We found a bunch of new things actually. This is one of them, which is a particular like synergistic effect between manganese content in the soil and a particular genotype. Of this test crop, which actually has a really profound effect on the root architecture…”
