Deep Learning for Accelerated Long-Horizon Forecasting of Multicomponent Multiphase Microstructure Evolution in High-Entropy Alloys
Hamidreza Razavi, Nele Moelans
The paper introduces a surrogate model combining autoencoders, graph convolutional networks, and LSTM to rapidly predict long‑term microstructure evolution in multicomponent high‑e…
Oracle-Budgeted Molecular Optimization with Short-Term Graph Memory
Jiannan Yang, Veronika Thost, Xiang Ling +1
The paper proposes a short-term graph memory module that uses an online graph neural surrogate to pre‑screen candidate molecules, allowing a fixed oracle budget to be spent on high…
Learning features from Newton's algorithm: a way to accelerate nonlinear parametrized PDE solvers
Rémy Vallot, Florian de Vuyst, Thibault Dairay +1
The paper introduces a two‑stage method that learns features from precomputed Newton trajectories to predict a surrogate solution and then apply a cheap corrective step, providing…
Surrogate assisted diversity estimation in neural ensemble search
Alexandr Udeneev, Petr Babkin, Oleg Bakhteev
The paper proposes a dual‑objective surrogate‑guided method for neural ensemble search that predicts both accuracy and diversity of candidate architectures, enabling efficient cons…
AlphaSchema: Exploring the Space of Trading Semantics for LLM-Based Alpha Mining
Jingyang Yi, Jian Yang, Yifei Jin +2
AlphaSchema is a framework that builds a structured semantic space for trading factor generation, letting large language models explore and implement candidate factors separately w…
From Crop and Energy Data to Optimized Lighting Scheduling: A Surrogate-Based MILP Framework for Vertical Farming
Francesco Ceccanti, Andrea Baccioli, Aldo Bischi
The paper presents a surrogate-based mixed‑integer linear programming framework to schedule artificial lighting in hydroponic vertical farms, reducing electricity use and cost whil…
