  1. 6. Clustering of Unevenly Spaced Mixed Data Time Series

    University essay from KTH/Matematisk statistik

    Author : Pierre Sinander; Asik Ahmed; [2023]
    Keywords : mixed data time series; unevenly spaced time series; clustering; dynamic time warping; Gower dissimilarity; time warping regularisation; numeriska och kategoriska tidsserier; ojämnt fördelade tidsserier; kluster analys; dynamic time warping; Gower dissimilaritet; regularisering av tidsförvränging;

    Abstract : This thesis explores the feasibility of clustering mixed data and unevenly spaced time series for customer segmentation. The proposed method implements the Gower dissimilarity as the local distance function in dynamic time warping to calculate dissimilarities between mixed data time series. READ MORE

  2. 7. Radio Environment Classification

    University essay from Umeå universitet/Institutionen för fysik

    Author : Daniel Hagström; [2023]
    Keywords : ;

    Abstract : This thesis has looked into the possibility of classifying radio environment scenarios based on data received in base stations. It was done in order to improve forecasting of electrical output in these base stations. READ MORE

  3. 8. AUGMENTATION AND CLASSIFICATION OF TIME SERIES FOR FINDING ACL INJURIES

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Marie-Louise Johansson; [2022]
    Keywords : computer science; machine learning; motion analysis; reconstructed ACL; anterior cruciate ligament; time series forest; dynamic time wapring; ACL; multivariate time series clasification; MTSC; time series classification; TSC; euclidean barycentric average; euclidean barycentric averaging; autmentation of time series; augmentation of multivariate time series; data augmentation; augmentation;

    Abstract : This thesis addresses the problem where we want to apply machine learning over a small data set of multivariate time series. A challenge when classifying data is when the data set is small and overfitting is at risk. Augmentation of small data sets might avoid overfitting. READ MORE

  4. 9. Automatic Annotation of Speech: Exploring Boundaries within Forced Alignment for Swedish and Norwegian

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Klaudia Biczysko; [2022]
    Keywords : forced alignment; automatic speech recognition; ASR; natural language processing; under-resourced languages; Swedish; Norwegian; CTC segmentation; wav2vec2; kaldi; HTK; dynamic time warping;

    Abstract : In Automatic Speech Recognition, there is an extensive need for time-aligned data. Manual speech segmentation has been shown to be more laborious than manual transcription, especially when dealing with tens of hours of speech. READ MORE

  5. 10. LSTM Feature Engineering Through Time Series Similarity Embedding

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Sebastian Bångerius; [2022]
    Keywords : Embedding; time series; LSTM; feature engineering; DTW; correlation; prediction;

    Abstract : Time series prediction has many applications. In cases with simultaneous series (like measurements of weather from multiple stations, or multiple stocks on the stock market)it is not unlikely that these series from different measurement origins behave similarly, or respond to the same contextual signals.
