Job Description

Join our Team

About this opportunity:

Join Ericsson for a master thesis focused on investigating and implementing global statistical models of live 5G mobile network data traffic. Your work will support the dimensioning of future hardware and software architectures, helping balance capacity, performance, and cost. Finding the right tradeoff has the potential to save Ericsson hundreds of millions of SEK annually and forms part of our continuous efforts to improve network dimensioning methodologies.

What you will do:

You will explore supervised learning approaches, including probabilistic classification and regression, for modeling millisecond-level network data traffic. Your work will cover algorithm selection and parameter tuning, data rebalancing for highly imbalanced datasets, class selection or clustering, feature selection and dimensionality reduction, synthetic data generation using SMOTE-like methods, and the selection of suitable model performance and evaluation metrics. You will also investigate how well models generalize across different geographical areas and address big-data implementation constraints related to processing and storage. The expected outcome is a report describing the selected processing pipeline and the reasoning behind it, together with an application for model generation and inference, including performance evaluation.

The skills you bring:

• Strong foundation in mathematics and supervised learning, including model selection, probabilistic classification, and probabilistic regression
• Familiarity with data rebalancing, class selection, feature selection and reduction, model evaluation, and model generalization
• Good at working with big-data processing and storage constraints
• Interest in applying machine learning to real-world 5G network challenges
