1. 1. Decoding communication of non-human species - Unsupervised machine learning to infer syntactical and temporal patterns in fruit-bats vocalizations.

   University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

   Author : Luigi Assom; [2023]
   Keywords : animal decision making; unsupervised machine learning; UMAP; autoencoders; classifiers; bioacoustics; combinatory syntax; animal communication;

   Abstract : Decoding non-human species communication offers a unique chance to explore alternative intelligence forms using machine learning. This master thesis focuses on discreteness and grammar, two of five linguistic areas machine learning can support, and tackles inferring syntax and temporal structures from bioacoustics data annotated with animal behavior.

3. 2. Multivariate Data Analysis on (Ti,Al)N Arc-PVD coating process : MVDA of the growth parameters thickness, stress,composition, and cutting performance

   University essay from Uppsala universitet/Oorganisk kemi

   Author : Per-Olof Öqvist; [2021]
   Keywords : chemistry; material; coating; statistics; PLS; PCA; kemi; material; beläggning; statistik; PLS; PCA;

   Abstract : This diploma work was done at Seco Tools AB (SECO) in Fagersta and aimed to evaluate the possibility to model the relationship between deposition data, deposition properties and, cutting performance of a (Ti,Al)N coating on cutting inserts by applying the Multivariate Data Analysis (MVDA) modeling technique Partial Least Squares Projection to Latent Structures Modeling (PLS). Cathodic Arc Deposition (Arc-PVD) was the PVD technique focused on this study. READ MORE

4. 3. Spatial Variation of THg and MeHg Stream Concentrations and Its Relation to TOC

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Maria Tranvik; [2017]
   Keywords : Mercury; organic matter; catchment characteristics; GIS; deforestation; Kvicksilver; organiskt material; avrinningsområdesfaktorer; GIS; skogsavverkning;

   Abstract : Mercury (Hg) which originates from global emissions to the atmosphere can deposit far away from the source. There is often a weak correlation between Hg deposition and concentrations in runoff, therefore catchment specific parameters might be of importance in controlling the amount of Hg ending up in watercourses and fish.

5. 4. Alzheimer's Disease Classification using K-OPLS and MRI

   University essay from Medicinsk informatik; Tekniska högskolan

   Author : Farshad Falahati Asrami; [2012]
   Keywords : Alzheimer’s Disease; Age correction; Classification; K-OPLS; MCI; MRI;

   Abstract : In this thesis, we have used the kernel based orthogonal projection to latent structures (K-OPLS) method to discriminate between Alzheimer's Disease patients (AD) and healthy control subjects (CTL), and to predict conversion from mild cognitive impairment (MCI) to AD. In this regard three cohorts were used to create two different datasets; a small dataset including 63 subjects based on the Alzheimer’s Research Trust (ART) cohort and a large dataset including 1074 subjects combining the AddNeuroMed (ANM) and the Alzheimer’s Disease Neuroimaging Initiative (ADNI) cohorts.

6. 5. Explorative Multivariate Data Analysis of the Klinthagen Limestone Quarry Data

   University essay from Institutionen för informationsteknologi

   Author : Linus Bergfors; [2010]
   Keywords : Multivariate analysis; interpolation; PCA; principal component analysis; PLS; projection to latent structures; partial least squares; Limestone quarry; Klinthagen; Kriging.; Multivariat analys; interpolation; PCA; principalkomponentsanalys; PLS; projektion till latenta strukturer; partiell minstakvadrat- anpassning; Kalkbrott; Klinthagen; Kriging;

   Abstract :   The today quarry planning at Klinthagen is rough, which provides an opportunity to introduce new exciting methods to improve the quarry gain and efficiency. Nordkalk AB, active at Klinthagen, wishes to start a new quarry at a nearby location. READ MORE
