GASL: Guided Attention for Sparsity Learning in Deep Neural Networks

2 code implementations7 Jan 2019 Amirsina Torfi, Rouzbeh A. Shirvani, Sobhan Soleymani, Naser M. Nasrabadi

The main goal of network pruning is imposing sparsity on the neural network by increasing the number of parameters with zero value in order to reduce the architecture size and the computational speedup.

Generalized Bilinear Deep Convolutional Neural Networks for Multimodal Biometric Identification

no code implementations3 Jul 2018 Sobhan Soleymani, Amirsina Torfi, Jeremy Dawson, Nasser M. Nasrabadi

We demonstrate that, rather than spatial fusion at the convolutional layers, the fusion can be performed on the outputs of the fully-connected layers of the modality-specific CNNs without any loss of performance and with significant reduction in the number of parameters.

Text-Independent Speaker Verification Using 3D Convolutional Neural Networks

5 code implementations26 May 2017 Amirsina Torfi, Jeremy Dawson, Nasser M. Nasrabadi

In our paper, we propose an adaptive feature learning by utilizing the 3D-CNNs for direct speaker model creation in which, for both development and enrollment phases, an identical number of spoken utterances per speaker is fed to the network for representing the speakers' utterances and creation of the speaker model.
