1. 1. The impact of parsing methods on recurrent neural networks applied to event-based vehicular signal data

   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

4. 3. Step-wise smoothing of ZUPT-aided INS

   University essay from KTH/Signalbehandling

   Author : David Colomar Simón; [2012]
   Keywords : ;

   Abstract : Due to the recursive nature of most foot-mounted zero-velocityupdate-aided (ZUPT-aided) inertial navigation systems (INSs), the error covariance increases throughout each step and "collapses" at the end of the step, where the ZUPT correction is done. This gives sharp corrections and discontinuities in the estimated trajectory. READ MORE
