• Abstract summary: Making reliable property predictions with machine learning can facilitate performance-based specification of concrete. We apply the methodology to specify a concrete mix that has high resistance to carbonation, and another concrete mix that has low environmental impact. Our generic methodology enables the exploitation of noise in machine learning, which has a broad range of applications in structural engineering.

• Abstract: Development of robust concrete mixes with a lower environmental impact is challenging due to natural variability in constituent materials and a multitude of possible combinations of mix proportions. Making reliable property predictions with machine learning can facilitate performance-based specification of concrete, reducing material inefficiencies and improving the sustainability of concrete construction. In this work, we develop a machine learning algorithm that can utilize intermediate target variables and their associated noise to predict the final target variable. We apply the methodology to specify a concrete mix that has high resistance to carbonation, and another concrete mix that has low environmental impact. Both mixes also fulfill targets on the strength, density, and cost. The specified mixes are experimentally validated against their predictions. Our generic methodology enables the exploitation of noise in machine learning, which has a broad range of applications in structural engineering and beyond.

  We introduce Matched Machine Learning, a framework that combines the flexibility of machine learning black boxes with the interpretability of matching. Our framework uses machine learning to learn an optimal metric for matching units and estimating outcomes. We show empirically that instances of Matched Machine Learning perform on par with black-box machine learning methods and better than existing matching methods for similar problems.

  In this paper, we examine a modular, Machine Learning-based approach for fatigue strength estimation.
