通过使用嗅觉显示器混合多种气味成分，可以实现多种气味。由于一组气味成分，以涵盖整个范围的气味还没有被知道，我们研究了一种方法，选择气味成分使用大规模的质谱数据库。采用非负矩阵分解（NMF）方法提取气味成分的基向量。然后，利用非负最小二乘法得到目标气味的配方。在可容忍的误差范围内，从10，000个化合物中成功地获得了基向量。用32-50个基向量可以近似计算出由322种化合物组成的104种气味的质谱。
A variety of smells can be realized by blending multiple odor components using an olfactory display. Since a set of odor components to cover the entire range of smells has not yet been known, we studied a method of selecting odor components using a large-scale mass spectrum database. Basis vectors corresponding to odor components were extracted by the NMF (nonnegative matrix factorization) method. Then, the recipe of the target odor was obtained using the nonnegative least-squares method. The basis vectors were successfully obtained from 10,000 compounds within a tolerable error. Moreover, the mass spectra of 104 odors composed of 322 compounds could be approximated using 32-50 basis vectors.
