Percolation Dynamics in Optimization: Variance Cascades and Nested Symmetry

Sai Niranjan Ramachandran, Suvrit Sra

We study the dynamics of Stochastic Gradient Descent (SGD), which is known to steer deep neural networks toward invariant sets that correspond to simpler subnetworks. How this stee…

Active Inference as Context Acquisition for AI Agents

Sanchayan Dutta, Sai Niranjan Ramachandran, Suvrit Sra

Interactive AI agents must acquire the right context as efficiently as possible. When a user omits a constraint, preference, file, or task variable, an agent can proceed with a def…

Trees to Flows and Back: Unifying Decision Trees and Diffusion Models

Sai Niranjan Ramachandran, Suvrit Sra

Decision trees and diffusion models are ostensibly disparate model classes, one discrete and hierarchical, the other continuous and dynamic. This work unifies the two by establishi…

KELP: Robust Online Log Parsing Through Evolutionary Grouping Trees

Satyam Singh, Sai Niranjan Ramachandran

Real-time log analysis is the cornerstone of observability for modern infrastructure. However, existing online parsers are architecturally unsuited for the dynamism of production e…

Cross-fluctuation phase transitions reveal sampling dynamics in diffusion models

Sai Niranjan Ramachandran, Manish Krishan Lal, Suvrit Sra

We analyse how the sampling dynamics of distributions evolve in score-based diffusion models using cross-fluctuations, a centered-moment statistic from statistical physics. Specifi…

Towards disease-aware image editing of chest X-rays

Aakash Saboo, Sai Niranjan Ramachandran, Kai Dierkes +1

Disease-aware image editing by means of generative adversarial networks (GANs) constitutes a promising avenue for advancing the use of AI in the healthcare sector. Here, we present…
