1. 1. Text to Music Audio Generation using Latent Diffusion Model : A re-engineering of AudioLDM Model

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ernan Wang; [2023]
   Nyckelord :Text to Music Audio Generation; Latent Diffusion; AudioLDM; Sampling Methods; Denoising Diffusion Probabilistic Model DDPM ; Denoising Diffusion Implicit Model DDIM ; Text till musik Ljudgenerering; Latent Diffusion; AudioLDM; Samplingsmetoder; DDPM; DDIM;

   Sammanfattning : In the emerging field of audio generation using diffusion models, this project pioneers the adaptation of the AudioLDM model framework, initially designed for text-to-daily sounds generation, towards text-to-music audio generation. This shift addresses a gap in the current scope of audio diffusion models, predominantly focused on everyday sounds. LÄS MER

3. 2. Highway Traffic Forecasting with the Diffusion Model : An Image-Generation Based Approach

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Pengnan Chi; [2023]
   Nyckelord :Diffusion model; Traffic forecasting; Generative model; Image processing; Spatial temporal modelling; Diffusionsmodell; Trafikprognos; Generativ modell; Bildbehandling; Rumsligtemporal modellering;

   Sammanfattning : Forecasting of highway traffic is a common practice for real traffic information system, and is of vital importance to traffic management and control on highways. As a typical time-series forecasting task, we want to propose a deep learning model to map the historical sensory traffic values (e.g., speed, flow) to future traffic forecasts. LÄS MER

4. 3. Generating Synthetic CT Images Using Diffusion Models

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Salih Saleh; [2023]
   Nyckelord :Machine learning; artificial intelligence; generative models; diffusion models; MRI; CT; synthetic CT; radiation therapy;

   Sammanfattning : Magnetic resonance (MR) images together with computed tomography (CT) images are used in many medical practices, such as radiation therapy. To capture those images, patients have to undergo two separate scans: one for the MR image, which involves using strong magnetic fields, and one for the CT image which involves using radiation (x-rays).

5. 4. Adapting the bundle of capillary tubes model (BCTM) for vertical soil solute transport modelling

   Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

   Författare :Martin Larsson; [2019]
   Nyckelord :soil solute vertical transport modelling vadose; Earth and Environmental Sciences;

   Sammanfattning : This study explores an approach for adapting the bundle of capillary tubes soil model for vertical soil solute transport modelling. The soil is split into thin layers allowing vertical water flow between capillaries of differing width with concomitant advective flow of solutes. Diffusion is included to improve realism. LÄS MER
