  1. 11. An Investigation of Low-Rank Decomposition for Increasing Inference Speed in Deep Neural Networks With Limited Training Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Victor Wikén; [2018]
    Keywords : deep neural networks; convolutional neural networks; AlexNet; inference speed; optimization; low-rank tensor decomposition; fine-grained classification problem; dog breed classification; transfer learning;

    Abstract : In this study, to increase inference speed of convolutional neural networks, the optimization technique low-rank tensor decomposition has been implemented and applied to AlexNet which had been trained to classify dog breeds. Due to a small training set, transfer learning was used in order to be able to classify dog breeds. READ MORE

  3. 12. Speeding up PARAFAC : Approximation of tensor rank using the Tucker core

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Lukas Arnroth; [2018]
    Keywords : Tucker decomposition; PARAFAC; tensor rank; split-half analysis;

    Abstract : In this paper, the approach of utilizing the core tensor from the Tucker decomposition, in place of theuncompressed tensor, for nding a valid tensor rank for the PARAFAC decomposition is considered.Validity of the proposed method is investigated in terms of error and time consumption.

  4. 13. The Square-Root Isometry of Coupled Quadratic Spaces : On the relation between vielbein and metric formulations of spin-2 interactions

    University essay from Stockholms universitet/Fysikum; Stockholms universitet/Oskar Klein-centrum för kosmopartikelfysik (OKC)

    Author : Kocic Mikica B.; [2014]
    Keywords : modified gravity; bigravity; bimetric theory; square-root isometry;

    Abstract : Bimetric theory is an extension to general relativity that introduces a secondary symmetric rank-two tensor field. This secondary spin-2 field is also dynamical, and to avoid the Boulware-Deser ghost issue, the interaction between the two fields is obtained through a potential that involes the matrix square-root of the tensors.

  5. 14. Analysis of 2 x 2 x 2 Tensors

    University essay from Matematiska institutionen

    Author : Ana Rovi; [2010]
    Keywords : Tensor decomposition. PARAFAC decomposition. Alternating Least Squares. Tensor Rank. Typical and generic rank. Best lower-rank approximation. Tensor Toolbox for MATLAB. Degeneracy. Uniqueness. Tensor classification.;

    Abstract : The question about how to determine the rank of a tensor has been widely studied in the literature. However the analytical methods to compute the decomposition of tensors have not been so much developed even for low-rank tensors. READ MORE
