When an auto labeling job is initiated by Ground Truth, a random sample of input data is selected and sent to Human workers for labeling. Upon the return of this data, a training set and a validation set are created. Ground Truth uses these datasets to train and validate the model used for auto labeling.

Much like with ML models, cross-validation is done by using a complementary subset of the data from the input data to evaluate the model. In Ground Truth auto labeling, this Validation set of data is periodically adjusted ( at every iteration of the labeling job) to improve the accuracy of the automated labels.

  • The number of validation set was reducing at each round, and this missing data was moving to the traning set.

    On the 1st round of traning, there was 1000 traning set and 501 validation set. On the 2nd round of traning there was 2202 traning set and 299 validation set. On the 3rd round of traning there was 3381 traning set and 120 validation set.

    I am curious about the machanism behind this.

    Thank you!
