Which database should be chosen to store the training and test samples for the neural network?

Question

Database

Hello! The task is to form training and test samples for a convolutional neural network. What is the best format for storing these samples? So far, I'm looking towards the MNIST format. Can you advise something else?

Answer 1

MNIST is not a DBMS, but a collection of special format image files and meta information files.
How convenient, and store. It all depends on what software will write and read this information and on what programming skills you have.

1. If you like to work with binary files - use MNIST. There is no dependency on third party software.
   
2. If not, then after all, image files can be stored in the same JPEG / PNG, and meta-information - in the DBMS.
   A cool DBMS is not needed. Enough SQLite. To read image formats, you need to use libraries that work with the desired image formats.
   

Answer 2

I suggest you use the HP vertica DBMS, they have data sizes up to 1 TB for nothing.
the only thing that works only under Linux, BUT this problem is solved by installing VirtualBox and CentOS.
She has drivers for Java, C#, Python, etc.
The speed is faster than Oracle.
