Data aggregation, integration and analysis system and related devices and methods

A non-transitory computer-readable medium comprising memory with instructions encoded thereon for attribution of data to an algorithm, the instructions, when executed, causing one or more processors to perform operations, the instructions comprising instructions to:

• (a) register a pool of images on a ledger;
• (b) attribute each image of the pool of images with an image-specific truth data set on the ledger;
• (c) train a machine learning algorithm to one or more of the images and registering the training of the machine learning algorithm a plurality of parameters to the one or more images on the ledger;
• (d) register each modification made to the machine learning algorithm on the ledger and attributing its modification to image that resulted in the modification;
• and
• (e) assess performance of the machine learning algorithm with each modification on a test data set and attributing any change to the image that resulted in the change.
