Memora: A Harmonic Memory Representation Balancing Abstraction and Specificity

ICML 2026poster

Agent memory systems must accommodate continuously growing information while supporting efficient, context-aware retrieval for downstream tasks. Abstraction is essential for scaling agent memory, yet it often comes at the cost of specificity, obscuring the fine-grained details required for effective…

BEST-Route: Adaptive LLM Routing with Test-Time Optimal Compute

ICML 2025poster

Large language models (LLMs) are powerful tools but are often expensive to deploy at scale. LLM query routing mitigates this by dynamically assigning queries to models of varying cost and quality to obtain a desired tradeoff. Prior query routing approaches generate only one response from the select…

Minerva: A Programmable Memory Test Benchmark for Language Models

ICML 2025poster

How effectively can LLM-based AI assistants utilize their memory (context) to perform various tasks? Traditional data benchmarks, which are often manually crafted, suffer from several limitations: they are static, susceptible to overfitting, difficult to interpret, and lack actionable insights--fail…

On Evaluating LLMs’ Capabilities as Functional Approximators: A Bayesian Evaluation Framework

COLING 2025main

Recent works have successfully applied Large Language Models (LLMs) to function modeling tasks. However, the reasons behind this success remain unclear. In this work, we propose a new evaluation framework to comprehensively assess LLMs’ function modeling abilities. By adopting a Bayesian perspective…

LLMLingua-2: Data Distillation for Efficient and Faithful Task-Agnostic Prompt Compression

ACL 2024findings

This paper focuses on task-agnostic prompt compression for better generalizability and efficiency. Considering the redundancy in natural language, existing approaches compress prompts by removing tokens or lexical units according to their information entropy obtained from a causal language model suc…
