1. 6. Out-of-distribution Recognition and Classification of Time-Series Pulsed Radar Signals

   University essay from KTH/Matematisk statistik

   Author : Paul Hedvall; [2022]
   Keywords : Out-of-Distribution; Gaussian Mixture Models; Dirichlet Process Mixture Models; Deinterleaving; Radar classification; Time-series analysis; Pulsed radar signals; Out-of-Distribution; Gaussian Mixture Models; Dirichlet Process Mixture Models; Deinterleaving; Radar classification; Time-series analysis; Pulsed radar signals;

   Abstract : This thesis investigates out-of-distribution recognition for time-series data of pulsedradar signals. The classifier is a naive Bayesian classifier based on Gaussian mixturemodels and Dirichlet process mixture models. READ MORE

3. 7. Approximating Quasistationary Distributions Using Deep Learning

   University essay from KTH/Matematisk statistik

   Author : Björn Wehlin; [2022]
   Keywords : Applied Mathematics; Deep Learning; Probability Theory; Stochastic Processes; Ito Diffusions; Quasistationary Distributions; Tillämpad matematik; djupinlärning; sannolikhetsteori; stokastiska processer; Ito-diffusioner; kvasistationära fördelningar;

   Abstract : We study a class of It\={o} diffusion processes on domains with smooth boundary, at which the process is killed. Such a process, when conditioned on non-extinction, gives rise to a stationary state known as a \emph{quasistationary distribution} (QSD). READ MORE

4. 8. A Confirmatory Analysis for Automating the Evaluation of Motivation Letters to Emulate Human Judgment

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Jorge Anibal Mercado Salazar; S M Masud Rana; [2021]
   Keywords : Motivation Letter; Natural Language Processing; Topic Modelling; Latent Dirichlet Allocation; Non-Negative Matrix Factorization; LDAVis; Topic; Factors; Image Processing; Text Processing; Logistic Regression; Unsupervised Learning; Machine Learning;

   Abstract : Manually reading, evaluating, and scoring motivation letters as part of the admissions process is a time-consuming and tedious task for Dalarna University's program managers. An automated scoring system would provide them with relief as well as the ability to make much faster decisions when selecting applicants for admission. READ MORE

5. 9. Topic propagation over time in internet security conferences : Topic modeling as a tool to investigate trends for future research

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Richard Johansson; Otto Engström Heino; [2021]
   Keywords : LDA; Latent Dirichlet Allocation; Machine learning; Web scraping; Topic Modeling;

   Abstract : When conducting research, it is valuable to find high-ranked papers closely related to the specific research area, without spending too much time reading insignificant papers. To make this process more effective an automated process to extract topics from documents would be useful, and this is possible using topic modeling. READ MORE
