2026The scaling of Large Language Models (LLMs) has driven significant performance gains but created substantial challenges in inference efficiency. While Mixture of Experts (MoEs) architectures address this by decoupling model size from inference cost, training MoEs from scratch is often unstable and compute intensive. Conversion of pre-trained dense models into sparse MoEs has emerged as an alternative solution

ACM CAIS 2026 Workshop on Agentic and AI Systems2026Compound AI systems that coordinate multiple specialized agents offer a promising path for complex reasoning tasks, yet principled architectural patterns for multi-agent coordination over structured data remain under-explored. We introduce Expansion-Contraction, a multi-agent graph traversal pattern in which an expansion phase walks a domain graph outward from a query origin, dynamically spawning ephemeral

KDD 20262026With the rapid advancement of powerful large language models (LLMs) in recent years, a wide range of software engineering tasks can now be addressed using LLMs, significantly enhancing productivity and scalability. Numerous benchmark datasets have been developed to evaluate the coding capabilities of these models, while they primarily focus on code generation and issue-resolution tasks. In contrast, we

We present ReSuMe, a general framework for mutual enhancement of dense retrieval systems and document summarizers through reinforcement learning. The framework jointly optimizes a language model for generating retrieval-oriented summaries and adapts the retrieval model to these summaries through alternating fine-tuning phases. We employ Group Relative Policy Optimization (GRPO) to fine-tune the language

IEEE SusTech 20262026In this paper, we present a comprehensive system-level approach to advancing device sustainability through power optimization for smart home devices, with a detailed case study of Amazon's Echo Pop. Through Lifecycle Assessment (LCA), we identified that Echo Pop generates an estimated 42 kg CO2e over its product lifetime, with 24 kg CO2e (57%) attributed to use-phase emissions, highlighting the critical
