Abstract

fetched live from OpenAlex

AI and Optimization through a geometric lensGeometry arises in a myriad ways across the sciences, and quite naturally within AI and optimization too.I'd like to share with you examples where geometry helps us understand problems in machine learning and optimization.Time permitting, I'd like to also mention new results in geometric sampling, e.g., when sampling from densities supported on a manifold, understanding geometry and the impact of curvature are crucial; surprisingly, progress on geometric sampling theory helps us understand certain generalization properties of SGD for deep-learning.Another fascinating viewpoint aorded by geometry is in non-convex optimization: geometry can either help us make training algorithms more practical (e.g., in deep learning), it can reveal tractability despite non-convexity (e.g., via geodesically convex optimization), or it can simply help us understand important ideas better (e.g., eigenvectors, LLM training, etc.).Ultimately, my hope is to oer the audience insights into geometric thinking, and to share with them some new tools that can help us make progress on modeling, algorithms, and applications.To make my discussion concrete, I will recall a few foundational results arising from our research, provide several examples, and note some open problems.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
