ProtInvTree: Deliberate Protein Inverse Folding with Reward-guided Tree Search
Designing protein sequences that fold into a target 3D structure, known as protein inverse folding, is a fundamental challenge in protein engineering. While recent deep learning methods have achieved impressive performance by recovering native sequences, they often overlook the one-to-many nature of the problem: multiple diverse sequences can fold into the same structure. This motivates the need for a generative model capable of designing diverse sequences while preserving structural consistenc…

MHTS: Multi-Hop Tree Structure Framework for Generating Difficulty-Controllable QA Datasets for RAG Evaluation
Existing RAG benchmarks often overlook query difficulty, leading to inflated performance on simpler questions and unreliable evaluations. A robust benchmark dataset must satisfy three key criteria: quality, diversity, and difficulty, which capturing the complexity of reasoning based on hops and the distribution of supporting evidence. In this paper, we propose MHTS (Multi-Hop Tree Structure), a novel dataset synthesis framework that systematically controls multi-hop reasoning complexity by leve…

Functional BART with Shape Priors: A Bayesian Tree Approach to Constrained Functional Regression
Motivated by the remarkable success of Bayesian additive regression trees (BART) in regression modelling, we propose a novel nonparametric Bayesian method, termed Functional BART (FBART), tailored specifically for function-on-scalar regression. FBART leverages spline-based representations for functional responses coupled with a flexible tree-based partitioning structure, effectively capturing complex and heterogeneous relationships between response curves and scalar predictors. To facilitate ef…

Ilford FP4 @ ISO 100 **English:** A black and white photograph showing a vertical white pipe with a black connector in the middle. The pipe is positioned in front of a background of horizontal ropes or wires, with a grassy ground visible below. **Chinese:** 一张黑白照片，展示了一根垂直的白色管道，中间有一个黑色连接器。管道前方的背景是水平的绳索或电线，下方可见草地。
Ilford FP4 @ ISO 80 **English:** A black and white photograph of a bare tree standing alone in an open field. The tree has a twisted trunk and sprawling branches without leaves, suggesting it might be late autumn or winter. The background includes a few more trees and a clear sky. **Chinese:** 一张黑白照片，展示了一棵孤独地站立在开阔田野中的光秃秃的树。这棵树有一个扭曲的树干和蔓延的枝条，没有叶子，表明可能是深秋或冬季。背景中还有一些树木和晴朗的天空。
Ilford FP4 @ ISO 80 **English:** A black and white photograph capturing a curved pathway with a person walking along it. The pathway is lined with shadows cast by a pergola structure overhead. The scene is set in a park-like environment with trees and greenery visible in the background. **Chinese:** 一张黑白照片，拍摄了一条弯曲的小径，一个人正沿着小径行走。小径两旁有由顶部的棚架结构投下的阴影。场景设在一个类似公园的环境中，背景中可见树木和绿地。
Ilford FP4 @ ISO 80 **English:** A black and white photograph of a wooden bench with ornate metal armrests situated on a paved walkway. The bench is empty except for a discarded plastic bottle lying on it. The background shows some greenery and plants, suggesting the bench is located in a park or garden. **Chinese:** 一张黑白照片，展示了一条铺砌的步道上放着一张带有精美金属扶手的木制长椅。长椅上空无一人，只有一个被丢弃的塑料瓶躺在上面。背景中有一些绿色植物，表明长椅位于公园或花园中。
