The principle of the Parser can be as follows:
路 Firstly, the Parser reads the chemical formula of an alloy (which is the first column in the mechanical property dataset).
路 Secondly, it cleans redundant symbols in the chemical formula (such as spaces and brackets).
路 Thereafter, it will normalise the proportion of different elements in the alloy composition. It will then provide the ratio for corresponding element and output a CSV file. The CSV file contains the 27 elements that appear in the dataset, along with the proportion of each element for each MPEA.
路 The final output is utilised in machine learning processes.
