Status of the SMArtInt Library: Simple Modelica Artificial Intelligence Interface

Abstract

This paper presents the current status of the open-sourceModelica library SMArtInt (Simple Modelica ArtificialIntelligence Interface), which offers users astraightforward and efficient approach of integratingartificial intelligence via neural networks directly intoModelica models. We provide a detailed overview of thelibrary’s features, area of application, and developmentprocess. The primary focus is on the diverse use cases ofSMArtInt. The new version 0.5.1 brings an exciting featurewith the support of the ONNX format. ONNX (Open NeuralNetwork Exchange) is an open, cross-platform format for therepresentation and exchange of deep learning models. Thismeans that in addition to TensorFlow models (TFLite), manyother models, such as PyTorch can now also run in SMArtIntvia the ONNX format.
