Abstract: Techniques for generating training datasets for machine learning algorithms are disclosed. An initial labelled dataset may be a noisy dataset with multiple misclassifications in labelling of the data. Human-based annotation and the application of historical data information are implemented to refine labels for a subset of data from the initial labelled dataset. After refinement of the subset of data, data with existing labels is extracted from the initial labelled dataset to add to the refined subset and generate a training dataset. The data that is extracted from the initial labelled dataset is data that is similar to data in the refined subset with the same label as the extracted data. The extraction of data according to similarities in the data is applied to scale the subset of data to a larger dataset while maintaining quality in order to provide a large, high-quality training dataset for the machine learning algorithm.
