  1. 1. Statistical Learning and Analysis on Homology-Based Features

    University essay from KTH/Matematisk statistik

    Author : Jens Agerberg; [2020]
    Keywords : Applied topology; topological data analysis; TDA; persistent homology; machine learning; Topologisk dataanalys; maskininlärning;

    Abstract : Stable rank has recently been proposed as an invariant to encode the result of persistent homology, a method used in topological data analysis. In this thesis we develop methods for statistical analysis as well as machine learning methods based on stable rank. READ MORE

  3. 2. The Cauchy-Schwarz inequality : Proofs and applications in various spaces

    University essay from Karlstads universitet/Avdelningen för matematik

    Author : Thomas Wigren; [2015]
    Keywords : Cauchy-Schwarz inequality; mathematical induction; triangle inequality; Pythagorean theorem; arithmetic-geometric means inequality; inner product space;

    Abstract : We give some background information about the Cauchy-Schwarz inequality including its history. We then continue by providing a number of proofs for the inequality in its classical form using various proof techniques, including proofs without words. READ MORE

  4. 3. Tuning of Learning Algorithms for Use in Automated Product Recommendations

    University essay from Lunds universitet/Matematisk statistik

    Author : Jakob Jäderbo; [2014]
    Keywords : Mathematics and Statistics;

    Abstract : In this thesis, we study the problem of predicting users' media preferences based on their, as well as other users' historical rating data. The model used is that a user's rating for an item can be explained by a sum of bias terms and an inner product between two vectors in some multidimensional feature space that is specic to the product domain.

  5. 4. Mellan här och där : en analys av stadens form ur ett gåendeperspektiv

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Christina Lagneby; [2014]
    Keywords : urban form; stråk; innerstad; modernism; gaturum; analysmetoder; Linköping;

    Abstract : Stadens form är en produkt av all tidigare stadsplanering. Ytmässigt har en stor del av våra städer vuxit fram under efterkrigstidens modernistiska stadsplanering, då funktionalitet, framkomliga transporter, ljus, luft och rymd resulterade i de glesa ytterstadsstrukturer vi ser på många platser idag.
