11. Iterative full-genome phasing and imputation using neural networks
University essay from Uppsala universitet/Människans evolutionAbstract : In this project, a model based on a convolutional neural network have been developed with the aim of imputing missing genotype data. This model was based on an already existing autoencoder that was modified into a U-Net structure. The network was trained and used iteratively with the intention that the result would improve in each iteration. READ MORE

12. 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

14. Imputing connections of random gene networks from time series data using ANNs
University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisationAbstract : This thesis presents the architecture of a convolutional neural network which is trained to impute the connections of randomly generated gene regulatory networks under varying amounts of regularisation. The generated gene networks are simulated from 10 different starting conditions for each set of connections in order to obtain multiple time series. READ MORE

15. IPW vs Imputation for Non-response : a simulation study
University essay from Stockholms universitet/Statistiska institutionenAbstract : The non-response is a growing issue and it is effecting the result of survey quality, it can there- fore not be ignored without substantial consequences. There are many methods on how to deal with non-response, both on how to avoid the non-response and how to minimise the con- sequences, like the non-response bias. READ MORE
