Don't Forget What You Just Learned: Self-Directed Repair Turns Agent Mistakes Into Lasting Lessons

Yuval Kansal, Karen Ullrich, Polina Kirichenko +4

Intelligent agents should learn from their mistakes so that experience leads to continuous improvement. Yet today's agents recover from a mistake only temporarily: in-context refle…

On-Policy Self-Distillation with Sampled Demonstrations Reduces Output Diversity

Andrei Liviu Nicolicioiu, Mohammad Pezeshki, Aaron Courville

On-policy self-distillation achieves strong pass@1 accuracy by using a single model as both teacher and student, with the teacher conditioned on a correct demonstration to provide…

ReasonCACHE: Teaching LLMs To Reason Without Weight Updates

Sharut Gupta, Phillip Isola, Stefanie Jegelka +4

Can Large language models (LLMs) learn to reason without any weight update and only through in-context learning (ICL)? ICL is strikingly sample-efficient, often learning from only…

Why Less is More (Sometimes): A Theory of Data Curation

Elvis Dohmatob, Mohammad Pezeshki, Reyhane Askari-Hemmat

This paper introduces a theoretical framework to resolve a central paradox in modern machine learning: When is it better to use less data? This question has become critical as clas…

Iterative Amortized Inference: Unifying In-Context Learning and Learned Optimizers

Sarthak Mittal, Divyat Mahajan, Guillaume Lajoie +1

Modern learning systems increasingly rely on amortized learning - the idea of reusing computation or inductive biases shared across tasks to enable rapid generalization to novel pr…

Beyond Multi-Token Prediction: Pretraining LLMs with Future Summaries

Divyat Mahajan, Sachin Goyal, Badr Youbi Idrissi +4

Next-token prediction (NTP) has driven the success of large language models (LLMs), but it struggles with long-horizon reasoning, planning, and creative writing, with these limitat…

Unveiling Simplicities of Attention: Adaptive Long-Context Head Identification

Konstantin Donhauser, Charles Arnal, Mohammad Pezeshki +3

The ability to process long contexts is crucial for many natural language processing tasks, yet it remains a significant challenge. While substantial progress has been made in enha…

Steering Large Language Model Activations in Sparse Spaces

Reza Bayat, Ali Rahimi-Kalahroudi, Mohammad Pezeshki +2

A key challenge in AI alignment is guiding large language models (LLMs) to follow desired behaviors at test time. Activation steering, which modifies internal model activations dur…

Improving the Scaling Laws of Synthetic Data with Deliberate Practice

Reyhane Askari-Hemmat, Mohammad Pezeshki, Elvis Dohmatob +6

Inspired by the principle of deliberate practice in human learning, we propose Deliberate Practice for Synthetic Data Generation (DP), a novel framework that improves sample effici…

The Pitfalls of Memorization: When Memorization Hurts Generalization

Reza Bayat, Mohammad Pezeshki, Elvis Dohmatob +2

Neural networks often learn simple explanations that fit the majority of the data while memorizing exceptions that deviate from these explanations.This behavior leads to poor gener…

Compositional Risk Minimization

Divyat Mahajan, Mohammad Pezeshki, Charles Arnal +3

Compositional generalization is a crucial step towards developing data-efficient intelligent machines that generalize in human-like ways. In this work, we tackle a challenging form…

Feedback-guided Data Synthesis for Imbalanced Classification

Reyhane Askari Hemmat, Mohammad Pezeshki, Florian Bordes +2

Current status quo in machine learning is to use static datasets of real images for training, which often come from long-tailed distributions. With the recent advances in generativ…

Discovering environments with XRM

Mohammad Pezeshki, Diane Bouchacourt, Mark Ibrahim +3

Environment annotations are essential for the success of many out-of-distribution (OOD) generalization methods. Unfortunately, these are costly to obtain and often limited by human…
