  1. 1. Tensor rank and support rank in the context of algebraic complexity theory

    University essay from KTH/Matematik (Avd.)

    Author : Pelle Andersson; [2023]
    Keywords : linear algebra; tensor product; tensor rank; matrix multiplication; complexity; linjär algebra; tensorprodukt; tensorrang; matrismultiplikation; komplexitet;

    Abstract : Starting with the work of Volker Strassen, algorithms for matrix multiplication have been developed which are time complexity-wise more efficient than the standard algorithm from the definition of multiplication. The general method of the developments has been viewing the bilinear mapping that matrix multiplication is as a three-dimensional tensor, where there is an exact correspondence between time complexity of the multiplication algorithm and tensor rank.

  3. 2. Pattern Mining in Uncertain Tensors

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

    Author : Aurélien Coussat; [2019]
    Keywords : ;

    Abstract : Data mining is the art of extracting information from data and creating useful knowledge. Itemset mining, or pattern mining, is an important subfield that consists in finding relevant patterns in datasets. READ MORE

  4. 3. Simple cosmological models and their descriptions of the universe

    University essay from Linköpings universitet/Matematik och tillämpad matematik

    Author : Emil Gustafsson; [2018]
    Keywords : Tensors; General relativity; Einstein s field equations; Cosmology; Friedmann s equation; FLRW-spacetimes; Tensorer; Allmän relativitetsteori; Einsteins fältekvationer; Kosmologi; Friedmanns ekvation; FLRW-rumtider;

    Abstract : Cosmology is the study of the universe as a whole, and attempts to describe the behaviour of the universe mathematically. The simplest relativistic cosmological models are derived from Einstein's field equations with the assumptions of isotropy and homogeneity. READ MORE

  5. 4. Experimental and Numerical Investigation of Ratcheting Effects in 316L Stainless Steel - The Two-Rod approach.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Gustav Eklund; [2014]
    Keywords : ;

    Abstract : This Master’s Thesis was conducted during spring 2014. An experimental and numerical investigation was conducted on the austenitic 316L stainless steel. The main focus of the study was the investigation of ratcheting effects. Experimentally, the main focus was the two-rod test, which had not been conducted previously. READ MORE

  6. 5. Tensor Rank

    University essay from Matematik och tillämpad matematik; Tekniska högskolan

    Author : Elias Erdtman; Carl Jönsson; [2012]
    Keywords : generic rank; symmetric tensor; tensor rank; tensors over finite fields; typical rank; generisk rang; symmetrisk tensor; tensorrang; tensorer över ändliga kroppar; typisk rang;

    Abstract : This master's thesis addresses numerical methods of computing the typical ranks of tensors over the real numbers and explores some properties of tensors over finite fields. We present three numerical methods to compute typical tensor rank. READ MORE
