| + | Data cleaning is essential preprocessing for analysing the data and extracting meaningful insights. Real data will typically include outliers, inconsistencies, missing data, repeated transactions possibly with different keys, and other kinds of acquisition errors. In geospatial trajectory data, there are even more sources of error, such as GPS inaccuracies. | ||
| + | The goal of this project is to survey the state of the art in geospatial trajectory data cleaning, both model-based and machine learning. The work also includes prototyping and empirically evaluating a selection of these methods in the MobilityDB system, and on different real datasets. These outcomes should serve as a base for a thesis project to enhance geospatial trajectory data cleaning. | ||
