Abstract
Provided are a data reduction method and a data processing device. The data processing device includes a memory configured to store target data expressed as a vector matrix and instructions for performing control over data reduction and a processor configured to determine low-rank matrices W1 and W2 from which a target parameter matrix W is constructable. The target parameter matrix W is constructed as the Hadamard product between the low-rank matrices W1 and W2.
Claims12
A data reduction method performed by a device including a processor and a memory configured to store instructions for controlling the processor to perform data reduction, the data reduction method comprising:
- receiving, by the memory, data expressed as a vector matrix;
- and
- determining, by the processor, low-rank matrices W1 and W2 from which a target parameter matrix W is constructable,
- wherein the target parameter matrix W is constructed as an Hadamard product between the low-rank matrices W1 and W2,
- the low-rank matrix W1 is constructed as an inner product of a matrix X1 having a size of m×r1 and a matrix Y1 having a size of n×r1, and
- the low-rank matrix W2 is constructed as an inner product of a matrix X2 having a size of m×r2 and a matrix Y2 having a size of n×r2 (m, n, r1, and r2 are natural numbers).
