  1. 26. Road Segmentation and Optimal Route Prediction using Deep Neural Networks and Graphs

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Viktor Ossmark; [2021]
    Nyckelord :statistics; applied mathematics; machine learning; computer vision; deep learning; satellite data; remote sensing; image segmentation; optimal routing; deep neural networks; graphs; AI; statistik; tillämpad matematik; maskininlärning; djup inlärning; datorseende; satellitdata; bildsegmentering; optimala rutter; grafer; AI;

    Sammanfattning : Observing the earth from above is a great way of understanding our world better. From space, many complex patterns and relationships on the ground can be identified through high-quality satellite data. LÄS MER

  3. 27. Unsupervised Image-to-image translation : Taking inspiration from human perception

    Magister-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Jens Jakob Sveding; [2021]
    Nyckelord :Artificial intelligence; Unsupervised learning; Image-to-Image translation; Generative Adversarial Networks; Structural Similarity Index Measure;

    Sammanfattning : Generative Artificial Intelligence is a field of artificial intelligence where systems can learn underlying patterns in previously seen content and generate new content. This thesis explores a generative artificial intelligence technique used for image-toimage translations called Cycle-consistent Adversarial network (CycleGAN), which can translate images from one domain into another.

  4. 28. Repairing Swedish Automatic Speech Recognition

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

    Författare :Karla Rehn; [2021]
    Nyckelord :Automatic speech recognition; Dialogue systems; Language models; ASR Repair; Automatisk taligenkänning; Dialogsystem; Språkmodeller; Reparation av taligenkänning;

    Sammanfattning : The quality of automatic speech recognition has increased dramatically the last few years, but the performance for low and middle resource languages such as Swedish is still far from optimal. In this project a language model trained on large written corpora called KB-BERT is utilized to improve the quality of transcriptions for Swedish. LÄS MER

  5. 29. Finding time-based listening habits in users music listening history to lower entropy in data

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

    Författare :John Magnusson; [2021]
    Nyckelord :Data mining; Clustering; Listening habits; Entropy.; Datautvinning; Klusteranalys; Lyssningsvanor; Entropi.;

    Sammanfattning : In a world where information, entertainment and e-commerce are growing rapidly in terms of volume and options, it can be challenging for individuals to find what they want. Search engines and recommendation systems have emerged as solutions, guiding the users. LÄS MER

  7. 30. Noise Reduction of Scintillation Camera Images Using UNET: A Monte Carlo Simulation Approach

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Johanna Korpijärvi; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background The project aims to reduce the noise in planar 111-In projections with a machine learning model. Method Sixteen base phantoms were used to create 696 phantoms in XCAT. An anterior planar projection was simulated with 111-In and ten uptake curves for each phantom in SIMIND. LÄS MER
