Recently, techniques of Yang-Baxter deformation have been developed to study deformations of string sigma model. The deformation can be regarded as the deformation of the target space, and the deformed background always satisfies the (generalized) supergravity equations of motion. We show that the (homogeneous) YB deformations are a kind of local O(d,d) transformation and discuss its generalization. This talk is based on a collaboration with Jun-ichi Sakamoto [arXiv:1803.05903].
