1. Clustering of Unevenly Spaced Mixed Data Time Series
University essay from KTH/Matematisk statistikAbstract : 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. Super-Resolution Vehicle Trajectory using Recurrent Time Series Imputation
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Vehicle data finds its use in a variety of applications in the fields of machine learning and data analysis. The volume of available data is limited by the frequency of data collection, and for several reasons, it can be infeasible to simply amplify this frequency. READ MORE

3. The impact of parsing methods on recurrent neural networks applied to event-based vehicular signal data
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This thesis examines two different approaches to parsing event-based vehicular signal data to produce input to a neural network prediction model: event parsing, where the data is kept unevenly spaced over the temporal domain, and slice parsing, where the data is made to be evenly spaced over the temporal domain instead. The dataset used as a basis for these experiments consists of a number of vehicular signal logs taken at Scania AB. READ MORE
