Deep Learning with Support Vector Machines To date, deep learning for classication using fully con- nected layers and convolutional layers have almost al- ways used softmax layer objective to learn the lower level parameters. 0 Lower layer weights are learned by backpropagating the gradients from the top layer linear SVM. Filters from convolutional net with softmax. There are exceptions, notably in papers by (Zhong & Ghosh, 2000; Collobert & Bengio, 2004; Nagi et al., 2012), supervised embedding with nonlinear NCA (Salakhutdinov & Hinton, 2007), and semi-supervised deep embedding (Weston et al., 2008). learns a recursive representation using linear SVMs at every layer, but without joint fine-tuning of the hidden representation. 0 One of the most prevailing and exciting supervised learning models with associated learning algorithms that analyse data and recognise patterns is Support Vector Machines (SVMs).
