1 giorno fa · Comparison results demonstrate that (1) the source data selection method is general and supports integration with various TL methods and distance metrics, (2) compared with using all source data, the proposed method can find a subset of source data from the same domain with better TL performance in metal AM regression tasks involving different processes and machines, and (3) when multiple ...
5 giorni fa · In many cases, we are working with data sets that contain more data than we need, or we want to inspect certain parts of the data set before we continue. Subsetting data sets can be challenging in base R, because there is a fair bit of repetition. This can make code difficult to readn and understand.
