Reconstructing Waddington’s Landscape from Data

Kavli Affiliate: Eric D. Siggia | Authors: Dillon J. Cislo, M Joaquina Delás, James Briscoe and Eric D. Siggia | Summary: The development of a zygote into a functional organism requires that this single progenitor cell gives rise to numerous distinct cell types. Attempts to exhaustively tabulate the interactions within developmental signaling networks that coordinate […]

Fundamental Physics with Pulsars around Sagittarius A$^star$

Kavli Affiliate: Lijing Shao | First 5 Authors: Lijing Shao, Lijing Shao, , , | Summary: Searching for radio pulsars orbiting around the Galactic centre black hole (BH), Sagittarius A$^star$ (Sgr A$^star$), represents a holy grail goal for large-area radio telescopes, in particular for the Square Kilometre Array. Follow-up timing observation of such a PSR-Sgr […]

Teaching LLMs to Speak Spectroscopy

Kavli Affiliate: Salman Habib | First 5 Authors: Nesar Ramachandra, Nesar Ramachandra, , , | Summary: Pre-trained Large Language Models (LLMs) have revolutionized text processing, yet adapting Transformer-based neural networks to non-textual scientific modalities typically requires specialized architectures and extensive computational resources. We demonstrate that LLaMA-3.1-8B can be efficiently repurposed to predict galaxy redshifts from […]

Structure-Adaptive Topology Optimization Framework for Photonic Band Gaps with TE-Polarized Sources

Kavli Affiliate: Feng Wang | First 5 Authors: Sukhad Dnyanesh Joshi, Sukhad Dnyanesh Joshi, , , | Summary: Leveraging our structure-adaptive topology optimization framework based on the integration of the photonic density of states over a frequency window for the TM polarization of light [see A. Bahulikar et al., arXiv:2411.09165 (2025)], we show that the […]

Exploring the Equivalence of Closed-Set Generative and Real Data Augmentation in Image Classification

Kavli Affiliate: Xiang Zhang | First 5 Authors: Haowen Wang, Haowen Wang, , , | Summary: In this paper, we address a key scientific problem in machine learning: Given a training set for an image classification task, can we train a generative model on this dataset to enhance the classification performance? (i.e., closed-set generative data […]

Episodic Memory Representation for Long-form Video Understanding

Kavli Affiliate: Long Zhang | First 5 Authors: Yun Wang, Yun Wang, , , | Summary: Video Large Language Models (Video-LLMs) excel at general video understanding but struggle with long-form videos due to context window limits. Consequently, recent approaches focus on keyframe retrieval, condensing lengthy videos into a small set of informative frames. Despite their […]

A Unified Contrastive-Generative Framework for Time Series Classification

Kavli Affiliate: Xiang Zhang | First 5 Authors: Ziyu Liu, Ziyu Liu, , , | Summary: Self-supervised learning (SSL) for multivariate time series mainly includes two paradigms: contrastive methods that excel at instance discrimination and generative approaches that model data distributions. While effective individually, their complementary potential remains unexplored. We propose a Contrastive Generative Time […]
