SubSearch: Robust Estimation and Outlier Detection for Stochastic Block Models via Subgraph Search

Leonardo Bianco, Christine Keribin, Zacharie Naulet

AISTATS 2025poster

Community detection is a fundamental task in graph analysis, with methods often relying on fitting models like the Stochastic Block Model (SBM) to observed networks. While many algorithms can accurately estimate SBM parameters when the input graph is a perfect sample from the model, real-world graph…

Decoding-time Realignment of Language Models

Tianlin Liu, Shangmin Guo, Leonardo Bianco, Daniele Calandriello, Quentin Berthet, Felipe Llinares-López +4

ICML 2024spotlight

Aligning language models with human preferences is crucial for reducing errors and biases in these models. Alignment techniques, such as reinforcement learning from human feedback (RLHF), are typically cast as optimizing a tradeoff between human preference rewards and a proximity regularization term…
