LOGOS: A Living Logic for AI Agent Teams That Evolve With Humans

Yuma Ichikawa, Yamato Arai, Kosaku Kimura +2

AI agents are evolving from answer engines into persistent teams that use tools, delegate work, learn from experience, and modify the artifacts that shape their future behavior. Th…

EVE-Agent: Evidence-Verifiable Self-Evolving Agents

Yamato Arai, Yuma Ichikawa

Self-evolving agents should not train on examples they cannot justify. Data-free self-evolving search agents offer a scalable route to systems that generate their own questions, an…

OneComp: One-Line Revolution for Generative AI Model Compression

Yuma Ichikawa, Keiji Kimura, Akihiro Yoshida +11

Deploying foundation models is increasingly constrained by memory footprint, latency, and hardware costs. Post-training compression can mitigate these bottlenecks by reducing the p…

Phase Transitions in a Modified Ising Spin Glass Model: A Tensor-Network-based Sampling Approach

Takumi Oshima, Yamato Arai, Koji Hukushima

Phase transitions in a modified Nishimori model, including the model considered by Kitatani, on a two-dimensional square lattice are investigated using a tensor-network-based sampl…

Quantization Error Propagation: Revisiting Layer-Wise Post-Training Quantization

Yamato Arai, Yuma Ichikawa

Layer-wise PTQ is a promising technique for compressing large language models (LLMs), due to its simplicity and effectiveness without requiring retraining. However, recent progress…

Adaptive Flip Graph Algorithm for Matrix Multiplication

Yamato Arai, Yuma Ichikawa, Koji Hukushima

This study proposes the "adaptive flip graph algorithm", which combines adaptive searches with the flip graph algorithm for finding fast and efficient methods for matrix multiplica…
