AI training data sets: Best practices and tips

18 Jan. 2023

The key to successful machine learning is the high level of quality of the data sets required to perform it. Before you start, you will need to prepare and process a certain amount and set of data. Let's figure out how to make this a reality!

The Significance of Preparing and Processing Data

Before diving into the details, it is important to understand that the information for data preprocessing must be up-to-date and well-selected. This criterion will certainly increase the arbitrariness of the model and improve the quality of work. Cleaning and normalizing data help to significantly reduce the level of errors and inaccuracies. And the ability to focus on the main data elements grows thanks to the function of generalizing new situations.


What are the typical steps taken to prepare and process data sets? 

  • Cleaning and normalizing data entail correcting errors or inconsistencies and preserving format uniformity. It may be essential to remove any missing or corrupted data or to convert all data to a similar scale or unit of measurement.
  • Data often contains a range of properties that may be used to train a model, but not all of these features are equally important or valuable. The model's performance may be improved, but the risk of over-fitting can be decreased by determining the most crucial characteristics.
  • Controlling defective or erroneous data: There are times when data is incomplete or contains errors that must be corrected. Methods such as interpolation and imputation can be used to fill gaps or correct errors.
  • Encoding data sets: Categorical variables, such as names or labels, may need to be turned into numerical form before the model can understand them. Label encoding and one-hot encoding are two techniques that may be utilized for this.

Data sets processing strategy

  1. Choose the right tools and preprocessing techniques: There are a variety of tools and preprocessing techniques available, so it's important to choose the ones that are most suited to your unique requirements. Consider elements including the nature and complexity of your data, the goals of your project, as well as your personal abilities and resources.
  2. Test your preprocessing procedures: It's a good idea to test your preprocessing procedures to make sure they are operating as intended before utilizing a preprocessed dataset to train a model. To accomplish this, you may compare the original and preprocessed datasets or train a straightforward model on the preprocessed data and assess how well it performs.
  3. Optimize for performance and efficiency: Try to optimize for performance and efficiency while assembling and preprocessing your datasets. This might entail adopting methods that are quicker or more memory-efficient, or it could entail utilising technologies that can automate particular processes.
  4. Keep accurate records of your preprocessing steps as you go through the data preparation and preprocessing process. It will be simpler to share your work with others and replicate your results as a result of it now.
  5. Think about data augmentation: In some scenarios, you might want to think about employing data augmentation techniques to increase your dataset and strengthen the generalizability of the model. By adding noise or using transformations, data augmentation includes creating new data based on the current data. When it concerns tasks like picture classification, where there may not be as many training examples as needed, this can be especially helpful.
