Master Thesis: Strategies for Missing ML Data Labels

Join our Team About this opportunity: As mobile networks are becoming increasingly complex, one way of increasing performance and making the mobile network more self-autonomous is to apply machine learning techniques. For example, machine learning can be used to predict signal strength for certain frequencies or cells given a position in the radio environment. Such prediction models rely on signal strength measurements carried out by real devices, where measurements may be imperfect or biased in different ways, causing bad predictions. A central challenge in building such models from operational network data is that a substantial fraction of measurements may be missing, either because the true signal falls below the hardware detection limit, a left-censoring mechanism, or because of transient reporting failures unrelated to signal strength. An earlier master thesis evaluated modelling strategies for frequency coverage models. The work in this thesis will focus on building cell coverage models instead, as well as refining the evaluation strategies for missing labels. The data set will consist of measurements already collected by Ericsson from a real radio access network. What you will do: * Investigate and compare different techniques for handling missing labels for cell coverage models. * Apply a selection of techniques to evaluate their performance. * The thesis will be concluded with a result presentation for the Ericsson development team. The skills you bring: * Master´s student in computer science, computer engineering or statistics and machine learning. Why join Ericsson? At Ericsson, you´ll have an outstanding opportunity.
