Industrializing Prediction-Powered Inference: The GLIDE Library for Reliable GenAI and Agentic Systems Evaluation
Grégoire Martinon, Ibrahim Merad, Mohammed Raki
Reliable evaluation of agentic systems requires unbiased estimates with valid uncertainty, but standard practice navigates between costly human annotation and biased LLM-as-judge p…
Convergence and concentration properties of constant step-size SGD through Markov chains
Ibrahim Merad, Stéphane Gaïffas
We consider the optimization of a smooth and strongly convex objective using constant step-size stochastic gradient descent (SGD) and study its properties through the prism of Mark…
Language verY Rare for All
Ibrahim Merad, Amos Wolf, Ziad Mazzawi +1
In the quest to overcome language barriers, encoder-decoder models like NLLB have expanded machine translation to rare languages, with some models (e.g., NLLB 1.3B) even trainable…
Robust Stochastic Optimization via Gradient Quantile Clipping
Ibrahim Merad, Stéphane Gaïffas
We introduce a clipping strategy for Stochastic Gradient Descent (SGD) which uses quantiles of the gradient norm as clipping thresholds. We prove that this new strategy provides a…
