This paper presents a study on the asymptotic diameter of the preferential attachment model, $\operatorname{PA}\!_n^{(m,\delta)}$, with parameters $m \ge 2$ and $\delta > 0$. The authors prove that the diameter of $G_n \sim \operatorname{PA}\!_n^{(m,\delta)}$ is $(1+o(1))\log_\nu n$ with high probability, confirming a conjecture and closing a gap in understanding the asymptotic diameter of preferential attachment graphs. This result has the potential to impact academic research in a broader range of models.
This paper presents a new approach, called Anomaly-Driven U-Net (adU-Net), for improving the identification of clinically significant prostate cancer (csPCa) in MRI images. By incorporating anomaly maps derived from MRI sequences, the adU-Net model outperforms existing methods and offers a promising direction for automated csPCa identification. This technique has the potential to create a lasting impact in academic research by improving the generalization and performance of automated segmentation methods.
This paper presents an improved Lanczos algorithm that utilizes the matrix product state representation to enhance its convergence and accuracy. This technique has the potential to significantly impact academic research by providing a more efficient and accurate method for finding multiple low-lying eigenstates, as demonstrated through numerical experiments on various models. Its scalability is also highlighted, making it a promising tool for future research in this field.
WebThinker is a deep research agent that enhances the performance of large reasoning models (LRMs) by allowing them to autonomously search the web, navigate web pages, and draft research reports. This is achieved through the integration of a Deep Web Explorer module and an Autonomous Think-Search-and-Draft strategy, as well as an RL-based training strategy. Extensive experiments show that WebThinker significantly outperforms existing methods and has the potential to improve the reliability and applicability of LRMs in complex scenarios, making it a valuable tool for academic research.
The paper presents a task-agnostic semantic communication (TASC) framework that utilizes information bottleneck theory and federated meta-learning to efficiently handle diverse tasks with multiple modalities in resource-constrained wireless networks. The proposed techniques show great potential to improve communication efficiency and provide user-centric services, making a lasting impact in academic research on semantic communication and its applications in pervasive intelligence.
The paper presents SWE-smith, a pipeline for generating large-scale training data for Language Models (LMs) in software engineering. This addresses a major challenge in the field, as existing datasets are small and require significant human labor to curate. With SWE-smith, the authors were able to create a dataset of 50k instances, an order of magnitude larger than previous works. This has the potential to greatly impact research in LM systems for automated software engineering, as it lowers the barrier of entry and allows for more scalable and usable data.
This paper presents a novel approach to modeling event sequences, specifically in electronic health records (EHRs), by combining the flexibility of neural networks with the interpretability of traditional Hawkes processes. The proposed method accurately captures self-reinforcing dynamics and achieves competitive performance on real-world datasets, while also providing clinically meaningful interpretations. This has the potential to greatly impact academic research in the field of healthcare by allowing for more accurate and interpretable modeling of complex event sequences.
The paper presents HetPFL, a method for effectively learning both local and global Pareto fronts in federated learning. By adaptively determining the optimal preference sampling distribution for each client and performing preference-aware fusion of clients' hypernets, HetPFL outperforms existing methods in terms of the quality of learned trade-off curves. This has the potential to greatly impact academic research in federated learning by improving the generalization and performance-fairness trade-offs in this field.
