Semi-overlapping Multi-bandit for Support Network Learning

Published:Dec 31, 2025 16:42
1 min read
ArXiv

Analysis

This paper introduces a novel framework, Sequential Support Network Learning (SSNL), to address the problem of identifying the best candidates in complex AI/ML scenarios where evaluations are shared and computationally expensive. It proposes a new pure-exploration model, the semi-overlapping multi-bandit (SOMMAB), and develops a generalized GapE algorithm with improved error bounds. The work's significance lies in providing a theoretical foundation and performance guarantees for sequential learning tools applicable to various learning problems like multi-task learning and federated learning.
Reference

“The paper introduces the semi-overlapping multi-(multi-armed) bandit (SOMMAB), in which a single evaluation provides distinct feedback to multiple bandits due to structural overlap among their arms.”

BOAD: Hierarchical SWE Agents via Bandit Optimization

Published:Dec 29, 2025 17:41
1 min read
ArXiv

Analysis

This paper addresses the limitations of single-agent LLM systems in complex software engineering tasks by proposing a hierarchical multi-agent approach. The core contribution is the Bandit Optimization for Agent Design (BOAD) framework, which efficiently discovers effective hierarchies of specialized sub-agents. The results demonstrate significant improvements in generalization, particularly on out-of-distribution tasks, surpassing larger models. This work is important because it offers a novel and automated method for designing more robust and adaptable LLM-based systems for real-world software engineering.
Reference

“BOAD outperforms single-agent and manually designed multi-agent systems. On SWE-bench-Live, featuring more recent and out-of-distribution issues, our 36B system ranks second on the leaderboard at the time of evaluation, surpassing larger models such as GPT-4 and Claude.”

1 min read
ArXiv

Analysis

This paper addresses the computational bottleneck of training Graph Neural Networks (GNNs) on large graphs. The core contribution is BLISS, a novel Bandit Layer Importance Sampling Strategy. By using multi-armed bandits, BLISS dynamically selects the most informative nodes at each layer, adapting to evolving node importance. This adaptive approach distinguishes it from static sampling methods and promises improved performance and efficiency. The integration with GCNs and GATs demonstrates its versatility.

SIC-Aided Bandit for Dynamic LoRa Resource Allocation

Published:Dec 26, 2025 17:27
1 min read
ArXiv

Analysis

This paper addresses the challenge of dynamic environments in LoRa networks by proposing a distributed learning method for transmission parameter selection. The integration of the Schwarz Information Criterion (SIC) with the Upper Confidence Bound (UCB1-tuned) algorithm allows for rapid adaptation to changing communication conditions, improving transmission success rate and energy efficiency. The focus on resource-constrained devices and the use of real-world experiments are key strengths.

      BanditPAM: Almost Linear-Time k-medoids Clustering via Multi-Armed Bandits

      Published:Dec 17, 2021 08:00
      1 min read
      Stanford AI

      Analysis

      This article announces the public release of BanditPAM, a new k-medoids clustering algorithm developed at Stanford AI. The key advantage of BanditPAM is its speed, achieving O(n log n) complexity compared to the O(n^2) of previous algorithms. This makes k-medoids, which offers benefits like interpretable cluster centers and robustness to outliers, more practical for large datasets. The article highlights the ease of use, with a simple pip install and an interface similar to scikit-learn's KMeans. The availability of a video summary, PyPI package, GitHub repository, and full paper further enhances accessibility and encourages adoption by ML practitioners. The comparison to k-means is helpful for understanding the context and motivation behind the work.
      Reference

      “In k-medoids, however, we require that the cluster centers must be actual datapoints, which permits greater interpretability of the cluster centers.”
