DeltaEvolve: Accelerating Scientific Discovery through Momentum-Driven Evolution

ICML 2026poster

LLM–driven evolutionary systems have shown promise for automated science discovery, yet existing approaches such as AlphaEvolve rely on full-code histories that are context-inefficient and potentially provide weak evolutionary guidance. In this work, we first formalize the evolutionary agents as a g…

ProCrop: Learning Aesthetic Image Cropping from Professional Compositions

AAAI 2026technical

Image cropping is crucial for enhancing the visual appeal and narrative impact of photographs, yet existing rule-based and data-driven approaches often lack diversity or require annotated training data. We introduce ProCrop, a retrieval-based method that leverages professional photography to guide c

Understanding Task Vectors in In-Context Learning: Emergence, Functionality, and Limitations

ICLR 2026poster

Task vector is a compelling mechanism for accelerating inference in in-context learning (ICL) by distilling task-specific information into a single, reusable representation. Despite their empirical success, the underlying principles governing their emergence and functionality remain unclear. This wo…

Analyzing Fine-Grained Alignment and Enhancing Vision Understanding in Multimodal Language Models

NeurIPS 2025poster

Achieving better alignment between vision embeddings and Large Language Models (LLMs) is crucial for enhancing the abilities of Multimodal LLMs (MLLMs), particularly for recent models that rely on powerful pretrained vision encoders and LLMs. A common approach to connect the pretrained vision encode…

Tracing Representation Progression: Analyzing and Enhancing Layer-Wise Similarity

ICLR 2025poster

Analyzing the similarity of internal representations within and across different models has been an important technique for understanding the behavior of deep neural networks. Most existing methods for analyzing the similarity between representations of high dimensions, such as those based on Center…

DREAM: Diffusion Rectification and Estimation-Adaptive Models

CVPR 2024poster

We present DREAM a novel training framework representing Diffusion Rectification and Estimation-Adaptive Models requiring minimal code changes (just three lines) yet significantly enhancing the alignment of training with sampling in diffusion models. DREAM features two components: diffusion rectific…

Generalized Neural Collapse for a Large Number of Classes

ICML 2024poster

Neural collapse provides an elegant mathematical characterization of learned last layer representations (a.k.a. features) and classifier weights in deep classification models. Such results not only provide insights but also motivate new techniques for improving practical deep models. However, most o…
