You may begin by importing your data into Alteryx using the "Input Data" feature. The tools "Filter," "Cleanse," "Formula," and "Join" may then be used to clean and prepare your data. You may eliminate unnecessary rows using the "Filter" tool, and you can standardise formats and get rid of unusual characters with the "Cleanse" tool. You may add additional columns and carry out mathematical operations with the "Formula" tool, and you can combine data from several sources with the "Join" tool.
To determine which learning techniques or tools to use in Alteryx for a specific dataset, you should first understand the problem you are trying to solve and the characteristics of your data. For example, if you are working with a large dataset, you may want to use tools such as "Sort" and "Sample" to manage the size of your data. If you are working with text data, you may want to use tools such as "Tokenize" and "Parse" to extract relevant information.
It would rely on the individual use case and data involved to identify a particularly difficult data-cleansing activity that Alteryx was able to complete. Nonetheless, coping with missing numbers, uneven formatting, and outliers are some typical difficulties in data cleansing. To assist you in overcoming these obstacles, Alteryx offers a number of tools, including the "Impute" tool for replacing missing data and the "Multi-Field Formula" tool for establishing uniform formatting across numerous columns.
