To eliminate these issues, this thesis introduces the use of algorithms as modeling priors to integrate specialized knowledge of domain experts into deep learning models. From both the empirical and theoretical perspective, this thesis explains how such algorithm inspired deep learning models can achieve improved interpretability and sample efficiency.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E2.\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp;Deep learning based algorithm design\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn conventional algorithm design, domain experts will first develop a model to describe the mechanism behind it and then establish a mathematical algorithm to find the solution. Notwithstanding its interpretability, this model-based method is inferior in terms of its limited effective range and accuracy. This is mostly due to the simplifying assumptions of the models which\u0026nbsp;often deviate from real-world problems. To address these issues, this thesis investigates the potential of deep learning based methods for discovering data-driven algorithms that adapt better to the interested problem distribution, from both the empirical and theoretical perspectives.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EDeep learning is a data-driven method, whereas conventional algorithm design is a knowledge-driven method.
