Pathway toward prior knowledge-integrated machine learning in engineering

no code implementations10 Jul 2023 Xia Chen, Philipp Geyer

Despite the digitalization trend and data volume surge, first-principles models (also known as logic-driven, physics-based, rule-based, or knowledge-based models) and data-driven approaches have existed in parallel, mirroring the ongoing AI debate on symbolism versus connectionism.

A Dynamic Feedforward Control Strategy for Energy-efficient Building System Operation

1 code implementation23 Jan 2023 Xia Chen, Xiaoye Cai, Alexander Kümpel, Dirk Müller, Philipp Geyer

The framework is integrated with a feedforward loop that embedded a dynamic building environment with leading and lagging system information involved: The simulation combined with system characteristic information is imported to the ML predictive algorithms.

Utilizing Domain Knowledge: Robust Machine Learning for Building Energy Prediction with Small, Inconsistent Datasets

no code implementations23 Jan 2023 Xia Chen, Manav Mahan Singh, Philipp Geyer

In this study, component-based machine learning (CBML) as the knowledge-encoded data-driven method is examined in the context of energy-efficient building engineering.

How Many Grid-Forming Converters Do We Need? A Perspective From Small Signal Stability and Power Grid Strength

no code implementations21 Sep 2022 Huanhai Xin, Chenxi Liu, Xia Chen, Yuxuan Wang, Eduardo Prieto-Araujo, Linbin Huang

Based on our analysis, we further study the problem of how to configure GFM converters in the grid and how many GFM converters we will need.

Explainable AI for engineering design: A unified approach of systems engineering and component-based deep learning

no code implementations30 Aug 2021 Philipp Geyer, Manav Mahan Singh, Xia Chen

Third, we evaluate explainability by qualitative and quantitative methods demonstrating the matching of preliminary knowledge and data-driven derived strategies and show correctness of activations at component interfaces compared to white-box simulation results (envelope components: R2 = 0. 92.. 0. 99; zones: R2 = 0. 78.. 0. 93).

PanoNet3D: Combining Semantic and Geometric Understanding for LiDARPoint Cloud Detection

no code implementations17 Dec 2020 Xia Chen, Jianren Wang, David Held, Martial Hebert

Visual data in autonomous driving perception, such as camera image and LiDAR point cloud, can be interpreted as a mixture of two aspects: semantic feature and geometric structure.
