In this paper, we present a sparse expression model as well as a training method which can learn the sparse transformation basis from compressive sensing measurement results rather than original historical data.

Compressive sensing is a low-rate sampling approach for the signals that are known to be sparse. Suppose the signal x is an N-dimensional vector, which can be sampled using a sensing matrix Φ∈RM×N as (9.1)y=Φx. The constant M determines the sampling rate. Because M is smaller than...
