WebWe showed that dictionary learning is an effective approach in addressing domain shifts under unsupervised setting. The general idea is to project data representations from multiple domains to the same latent space where their distributions are more similar. WebApplication of the incoherent dictionary learning algorithm to noise attenuation of seismic data demonstrates successful performance via two numerical examples. We conclude that the proposed incoherent dictionary learning algorithm can obtain a better compromise between noise reduction and signal protection than the state-of-the-art methods. how did chuichi nagumo died
