Furthermore, this quantization property could be maintained in the random projections of sparse features, if both the features and random projection matrices are sufficiently sparse.

Recently, it has been observed that {0, 1,-1}-ternary codes which are simply generated from deep features by hard thresholding, tend to outperform {-1, 1}-binary codes in image retrieval.

As a typical dimensionality reduction technique, random projection can be simply implemented with linear projection, while maintaining the pairwise distances of high-dimensional data with high probability.
