1. A method comprising:
reading encoded data from a group of memory cells of a memory subsystem;
obtaining population data for a number of memory cells in the group of memory cells having a read voltage within a range of read voltages the population data comprising:
a first number of memory cells with a read voltage less than a first threshold voltage; and
a second number of memory cells with a read voltage greater than the first threshold voltage and less than a second threshold voltage;
predicting, using a first trained machine learning model, that an estimated raw bit error rate of the encoded data satisfies a first threshold using the population data, wherein the estimated raw bit error rate is determined without performing an error correcting code decoding operation on the encoded data; and
initiating a first media management operation in response to determining that the estimated raw bit error rate satisfies the first threshold.
