Abstract
Methods and systems for copying weight values between weight arrays includes reading outputs from a first array and reading outputs from a second array. Differences between respective outputs of the first array and the second array are determined. Values of the second array are adjusted in accordance with the determined differences.
Claims20
A method for copying weight values between weight arrays, comprising:
- reading outputs from a first array;
- reading outputs from a second array;
- determining differences between respective outputs of the first array and the second array using a processor;
- and
- adjusting values of the second array in accordance with the determined differences.

A method for copying weight values between weight arrays, comprising:
- reading outputs from a first array that comprises a first plurality of weights implemented as respective resistive processing units;
- reading outputs from a second array that comprises a second plurality of weights implemented as respective resistive processing units;
- determining differences between respective outputs of the first array and the second array using a processor;
- adjusting values of the second array in accordance with the determined differences;
- and
- repeating the steps of reading outputs from the second array, determining differences, and adjusting values of the second array to iteratively decrease the differences between the outputs from the first array and the outputs from the second array.
