Neural networks for topology optimization [PDF]
Russian Journal of Numerical Analysis and Mathematical Modelling, 2019 Abstract In this research, we propose a deep learning based approach for speeding up the topology optimization methods. The problem we seek to solve is the layout problem. The main novelty of this work is to state the problem as an image segmentation task.

Topological Portfolio Selection and Optimization
4th ACM International Conference on AI in Finance, 2023 Modern portfolio optimization is centered around creating a low-risk portfolio with extensive asset diversification. Following the seminal work of Markowitz, optimal asset allocation can be computed using a constrained optimization model based on empirical covariance. However, covariance is typically estimated from historical lookback observations, and
