Cell-free synthetic biology has become a robust technology platform for synthesizing proteins and chemicals in recent years. Cell-free synthetic biology system activates biological machinery without the use of living cells, which opens new opportunities for the addition or synthesis of toxic substances at high concentrations in biological systems. Although it is generally accepted that an in vitro...
Previous sparse representation (SR) methods are constructed on the assumption that the test sample can be approximately expressed by a linear combination of all original training samples. However, in most real-world applications samples are not subject to this assumption. Consequently, it is significant to explore a new way to improve SR. In this paper, we propose two directional transform based sparse...
