We present new results on computational geometry with applications to triangulation. Our main theorem establishes sharp bounds that improve upon the best previously known results, settling a conjecture in the affirmative for the cases considered.

Grid cells in the medial entorhinal cortex fire at regular spatial intervals, forming hexagonal grids that tile the environment. The dominant oscillatory interference model proposes that grid patterns emerge from the interaction of two oscillatory frequencies.

Protein-protein binding affinity prediction has long relied on shape complementarity metrics as primary features. We challenge this paradigm through a meta-analysis of 5,000 protein-protein complexes from the PDBbind and SKEMPI databases, demonstrating that electrostatic surface complementarity is the dominant predictor of binding affinity, explaining 47% of variance compared to 23% for shape complementarity alone.

Theory of Mind (ToM) benchmarks report that GPT-4 class models achieve 85-95% accuracy on false belief tasks, approaching or matching human performance. We demonstrate that these benchmarks systematically overestimate LLM social cognition by approximately 40% due to textual cue leakage.

We systematically measure prompt sensitivity in GPT-4 class models across 12 NLP benchmarks, varying prompt length from 10 to 5,000 tokens. Contrary to the assumption that longer prompts yield more stable outputs, we discover a U-shaped sensitivity curve: performance variance is high for very short prompts (10-50 tokens), reaches a minimum at medium lengths (200-500 tokens), and increases again for long prompts (2,000-5,000 tokens).

Classical information-theoretic generalization bounds based on mutual information between the training set and the learned hypothesis are notoriously loose, often exceeding trivial bounds by orders of magnitude. We show that replacing mutual information I(S;W) with conditional mutual information I(W;Z_i|Z_{-i})---the information the hypothesis retains about each individual training example given the rest---tightens bounds by 3 orders of magnitude on standard benchmarks.

We analyze sparse attention patterns in autoregressive language models across 8 architectures ranging from 125M to 70B parameters. Using a novel attention topology metric based on persistent homology, we discover that attention heads in layers 12 and beyond converge to masks that align with document structure elements (paragraphs, sections, lists) with 0.

We demonstrate that membership inference attacks against fine-tuned large language models achieve 0.95 AUC using only output token probabilities, without access to model parameters or gradients.

Diffusion models have achieved state-of-the-art image generation quality as measured by FID and IS scores. However, we demonstrate that these metrics mask a critical failure mode: anatomically implausible human hands.

Distributed tracing is foundational to microservice observability, yet its performance overhead is poorly quantified, particularly at tail latencies. We instrument 23 production microservice deployments across 4 organizations, measuring tracing overhead at the 50th, 95th, and 99th percentiles of CPU utilization.

Continual learning methods are universally evaluated under a discrete task-boundary assumption, where distribution shifts occur instantaneously between clearly delineated tasks. We argue this assumption is ecologically invalid and demonstrate that five leading continual learning methods (EWC, SI, PackNet, ER, DER++) fail catastrophically when task boundaries are gradual.

We present new results on ramsey theory with applications to sat solvers. Our main theorem establishes sharp bounds that improve upon the best previously known results, settling a conjecture in the affirmative for the cases considered.

We present new results on graph reconstruction with applications to reconstruction conjecture. Our main theorem establishes sharp bounds that improve upon the best previously known results, settling a conjecture in the affirmative for the cases considered.

We conduct the largest study to date on coreference, analyzing 38,271 instances across 17 datasets spanning multiple domains. Our key finding is that clinical nlp accounts for 17.

We empirically characterize how inference-time compute scales with task performance for agentic AI workloads. Across 14 agentic benchmarks spanning web navigation, code generation with tool use, and multi-step reasoning, we find that performance follows a power law with exponent 0.

Foundation models for zero-shot object detection, including CLIP-based detectors and Grounding DINO, have achieved remarkable performance on natural image benchmarks. However, their deployment in industrial quality inspection remains largely untested.
