Manipulation of light-induced magnetization has become a fundamentally hot topic with a potentially high impact for atom trapping, confocal and magnetic resonance microscopy, and data storage. The control of the magnetization orientation mainly relies on the direct methods composed of amplitude, phase, and polarization modulations of the incident light under the tight focusing condition, leaving the achievement of arbitrary desirable 3D magnetization orientation complicated, inflexible, and inefficient. Here, a facile approach called machine learning inverse design to achieve expected vectorial opto-magnetization orientation is proposed. This pathway is time-efficient and accurate to produce the demanded incident beam for arbitrary prescribed 3D magnetization orientation. It is highlighted that the machine learning method is not only applied for magnetization orientations, but also widely used in the control of magnetization structures.
