    Estimating Missing Unit Process Data in Life Cycle Assessment Using a Similarity-Based Approach by Ping Hou (17213)

    Published 2018
    “…We use the ecoinvent 3.1 unit process data sets to test our method in four steps: (1) dividing the data sets into a training set and a test set; (2) randomly removing certain numbers of data in the test set indicated as missing; (3) using similarity-weighted means of various numbers of most similar processes in the training set to estimate the missing data in the test set; and (4) comparing estimated data with the original values to determine the performance of the estimation. …”
