1. 11. Reconstruction of Hyperspectral Images Using Generative Adversarial Networks

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Jacob Eek; [2021]
   Nyckelord :Coded aperture snapshot spectral imaging; CASSI; Raman; Raman spectroscopy; Explosive; Detection; Hyperspectral Image; HSI; Compressed sensing; Compressive Sensing; CS; Machine Learning; Reconstruction; Inverse problem; Generative Adversarial Network; GAN; CGAN; BEGAN; Latent variable optimization;

   Sammanfattning : Fast detection and identification of unknown substances is an area of interest for many parties. Raman spectroscopy is a laser-based method allowing for long range no contact investigation of substances. LÄS MER

3. 12. The relationship between innovation and creative climate: A quantitative study on the effects of creative climate dimensions on individual innovation behaviour

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Giulia Ortisi; [2020-10-15]
   Nyckelord :innovation; innovation output; innovation performance; creativity; creative climate; innovation measurements; individual behaviour; individual innovation; individual creativity;

   Sammanfattning : The aim of the research is to define which type of statistical relationship exist between the independent variables of creative climate and the dependent variable of innovation output on the individual level, and therefore defined as individual innovation behaviors. The research is assessed through quantitative study and the tool chosen to collect the data is a survey, whose aim is to measure how companies manage creative climate within their organizations and which type con effects this has on the individuals’ innovation behaviors.

4. 13. Executive Constraints and Civil Conflict Onset

   Master-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskning

   Författare :Joshua Krusell; [2020]
   Nyckelord :civil conflict; political science; bayesian;

   Sammanfattning : Do institutional constraints on a regime's executive decrease the likelihood of civil conflict onset? An unconstrained executive is free to loot state resources undermining the state's capacity to effectively deal with nascent rebellions, and may be more likely to engage in violent repression, especially in the form of indiscriminate violence. This can encourage political grievances, lead to a loss of legitimacy for the regime, and provide the opportunity for would be rebel groups to attract new members by offering protection against government violence.

5. 14. Deep Autoencoders for Compression in High Energy Physics

   Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Eric Wulff; [2020]
   Nyckelord :ATLAS; hadron jet; machine learning; autoencoder; dimensionality reduction; artificial intelligence; high energy physics; data compression; Physics and Astronomy;

   Sammanfattning : Current technological limitations make it impossible to store the enormous amount of data produced from proton-proton collisions by the ATLAS detector at CERN's Large Hadron Collider. Therefore, specialised hardware and software is being used to decide what data, or which proton-proton \textit{collision events}, to save and which to discard. LÄS MER

7. 15. Jump Estimation of Hidden Markov Models with Time-Varying Transition Probabilities

   Kandidat-uppsats, Lunds universitet/Matematisk statistik

   Författare :Henning Tansjö; [2020]
   Nyckelord :Jump estimation; Hidden Markov model; financial time series; clustering; unsupervised learning.; Mathematics and Statistics;

   Sammanfattning : The Hidden Markov model is applicable to a wide variety of fields. Applied to financial time series, its assumed underlying state sequence can reflect the time series' tendency to behave differently over different periods of time. In many situations, models could be improved by including exogenous data. LÄS MER
