The data should be cleaned, pre processed and converted into the required format necessary for the specific ML algorithm being used. For example, in case of numeric or categorical data there could be missing values that should be imputed. Values in certain columns may need to be bucketed. Unstructured data has to be formatted in the required input format. In case of text data, we may have to tokenize, lematize and perhaps also create an embedding of the text data. The possibilities are many and depends on the specific task at hand.

  • Could you walk me through the typical workflow you follow when cleaning and preparing data for use in machine learning models?
  • Explain the steps you typically take for data wrangling and cleaning prior to applying machine learning algorithms?
  • How do you approach cleaning and restructuring data to optimize its use in machine learning?
  • How do you ensure data cleanliness before feeding it into a machine learning model?
  • How do you ensure that the data you are feeding into machine learning algorithms is representative and unbiased?
  • Please explain the steps you take to turn raw data into something that a machine learning algorithm can interpret.
  • What are some of the prerequisites for clean data when it comes to machine learning, and how do you ensure they are all met?
