EBOD: An ensemble-based outlier detection algorithm for noisy datasets

Real-world datasets often comprise outliers (e.g., due to operational error, intrinsic variability of the measurements, recording mistakes, etc.) and, hence, require cleansing as a prerequisite to any meaningful machine learning analysis. However, …

Using machine learning to predict concrete's strength: Learning from small datasets

Despite enormous efforts over the last decades to establish the relationship between concrete proportioning and strength, a robust knowledge-based model for accurate concrete strength predictions is still lacking. As an alternative to physical or …

Predicting Concrete’s Strength by Machine Learning: Balance between Accuracy and Complexity of Algorithms

The properties of concretes are controlled by the rate of reaction of their precursors, the chemical composition of the binding phase(s), and their structure at different scales. However, the complex and multiscale structure of the cementitious …
