1. A system comprising:
a memory device; and
a processing device, operatively coupled to the memory device, to perform operations comprising:
determining a value of a data state metric associated with data stored in a part of a block of the memory device;
responsive to determining that the value of the data state metric satisfies a first threshold criterion, determining a first value reflecting a voltage distribution metric associated with at least the part of the block;
determining a second value reflecting at least one of a deterioration slope indicative of a data deterioration rate associated with a first portion of the memory device or an error rate associated with a second portion of the memory device;
feeding the first value and the second value to a neural network; and
receiving, from the neural network, an instruction to perform a media management operation to relocate the data to a new block of the memory device.
