Web5 de out. de 2024 · This should make the contractive objective easier to implement for an arbitrary encoder. For torch>=v1.5.0, the contractive loss would look like this: contractive_loss = torch.norm (torch.autograd.functional.jacobian (self.encoder, imgs, create_graph=True)) The create_graph argument makes the jacobian differentiable. … WebWe propose a novel regularizer when training an auto-encoder for unsupervised feature extraction.

Auto-Encoders in Deep Learning—A Review with New Perspectives

WebWe propose a novel regularizer when training an auto-encoder for unsupervised feature extraction. We explicitly encourage the latent representation to contract the input space … WebThe second order regularization, using the Hessian, penalizes curvature, and thus favors smooth manifold. We show that our proposed technique, while remaining computationally efficient, yields representations that are significantly better suited for initializing deep architectures than previously proposed approaches, beating state-of-the-art performance … Web7 de ago. de 2024 · Salah Rifai, Pascal Vincent, Xavier Muller, Xavier Glorot, and Yoshua Bengio. 2011.
