[en] Datasets for machine learning can be very large in size, and are usually transferred to dedicated servers that have the computing power necessary for complex model training.
This transfer is done losslessly by TCP, but could allow some losses without affecting too much the quality of the trained model, which would make the transfer faster.

The first part of this work looks at how packet loss on different datasets affect the accuracy of the corresponding model, and how the different ways to deal with packet loss compare to one another. It finds that it is indeed possible to lose packets during the transfer without affecting the model too much, but it requires some data preparation to repair the files if parts of it
are lost, and some parts cannot be lost and are absolutely necessary to the files.

Using those results, a protocol is designed and implemented to transfer datasets partly by TCP and partly by UDP depending on which parts of the files are required or can be lost without too many consequences. Focus is mainly set on JPEG files.
Tests then show that the protocol can be indeed be faster, but parameters need to be set to the right values or the ratio speed/loss becomes too bad.
