STRIDE: Training Data Attribution via Sparse Recovery from Subset Perturbations
Announce Type: new Abstract: Training Data Attribution (TDA) seeks to trace a model's predictions back to its training data. The gold standard for TDA relies on causal interventions, observing how a model changes when data is added or removed, but repeated retraining is computationally challenging for Large Language Models (LLMs). Consequently, most approaches approximate this effect in the parameter space using gradients.
Topological texture analysis of microscopy images of dynamic casein gelation and its relation to rheological properties
arXiv:2606.02048v1 Announce Type: cross Abstract: We propose a novel computational toolbox that integrates Topological Data Analysis (TDA), Differential Box Counting (DBC), Multifractal Partition (MFP), and Local Binary Patterns (LBP), applied to time-lapse super-resolution STED microscopy images of sodium caseinate gelation induced by glucono-delta-lactone (GDL) at 30 {\deg}C and 40 {\deg}C and two GDL concentrations (1.8% and 3.5% w/v). TDA tracked topological loops, closed ring-like...

Venezuelan gang members who entered US illegally plead guilty to gunning down two unarmed Americans
Federal authorities announced on Wednesday that four members of the notorious Venezuelan street gang Tren de Aragua (TdA) pleaded guilty to the May 2024 murders of two unarmed American citizens in New York City. The gang members, who entered the U.S. illegally, allegedly gunned down Claretha LaQuesha Daniels, 44, and Justin Lawless, 36, in the middle of a residential Bronx street, while also shooting and wounding a third victim, according to a statement from the U.S. Department of Justice...
Symmetric Divergence and Normalized Similarity: A Unified Topological Framework for Representation Analysis
arXiv:2606.06342v1 Announce Type: cross Abstract: Topological Data Analysis (TDA) offers a principled, intrinsic lens for comparing neural representations. However, existing paired topological divergences (e.g., RTD) are limited by heuristic asymmetry and, more critically, unbounded scores that depend on sample size, hindering reliable cross-scenario benchmarking. To address these challenges, we develop a unified topological toolkit serving two complementary needs: fine-grained structural...
Data Attribution in Large Language Models via Bidirectional Gradient Optimization
Announce Type: new Abstract: Large Language Models (LLMs) are increasingly deployed across diverse applications, raising critical questions for governance, accountability, and data provenance. Understanding which training data most influenced a model's output remains a fundamental open problem. We address this challenge through training data attribution (TDA) for auto-regressive LLMs by expanding upon the inverse formulation: How would training data be affected if the model had seen the...
