Jacob Hilton - Miniature mathematical mysteries: uninterpreted models w/ fewer than 1,500 parameters
Recorded 31 August 2026. Jacob Hilton of the Alignment Research Center presents "Miniature mathematical mysteries: uninterpreted models with fewer than 1,500 parameters" at IPAM's Foundations of Interpretability Workshop.Abstract: What would it mean to completely understand the internal computation of a frontier model? We approach this question by starting with models containing only dozens to hundreds of parameters. These models are trained on simple algorithmic tasks, such as identifying the position of the second-largest number in a sequence, but they can be remarkably challenging to fully interpret. We argue for a practical intermediate target: producing "deductive" (i.e., sample-free) estimates of the model’s loss that are at least as accurate as sampling-based estimates given the same computational budget. This target can be surprisingly difficult to achieve, and offers a concrete way for theoretical research to clarify and extend the limits of ambitious mechanistic interpretability.

TubeReader video aggregator is a website that collects and organizes online videos from the YouTube source. Video aggregation is done for different purposes, and TubeReader take different approaches to achieve their purpose.
Our try to collect videos of high quality or interest for visitors to view; the collection may be made by editors or may be based on community votes.
Another method is to base the collection on those videos most viewed, either at the aggregator site or at various popular video hosting sites.
TubeReader site exists to allow users to collect their own sets of videos, for personal use as well as for browsing and viewing by others; TubeReader can develop online communities around video sharing.

What is YouTube?
YouTube is a free video sharing website that makes it easy to watch online videos. You can even create and upload your own videos to share with others. Originally created in 2005, YouTube is now one of the most popular sites on the Web, with visitors watching around 6 billion hours of video every month.
