About this opportunity:

The operation of mobile networks is becoming increasingly autonomous and complex. AI agents are already being introduced into network operations to collect evidence, form diagnostic hypotheses, and recommend corrective actions.

These systems are typically organised as pipelines in which each agent has a defined task. For example, one agent gathers evidence, another reasons about the fault, and a subsequent agent proposes a diagnosis, logs, or a corrective action. When the final output is wrong or uncertain, an important question arises: was the failure caused by the uncertainty of the first agent, an independent failure in the second agent, or an interface between them that lost information?

The fundamental question of this thesis is what the agent and its surrounding platform must log so that a failure can be explained after the event without excessive cost, complexity, or exposure of sensitive network data.

The objective is to identify and experimentally evaluate the minimum logging information required to attribute failures in a selected telecommunications use case. The work corresponds to one or two students, 30 hp each. The location is Stockholm/Kista, and the preferred starting date is early January.

What you will do:

• Conduct a focused literature study on observability in LLM-based multi-agent systems, failure attribution, and error taxonomies.
• Perform a logging-ablation experiment by systematically removing log categories and measuring the effect on root-cause and first-error attribution.
• Analyse the trade-off between attribution value and logging cost, including trace size, latency, privacy, and operational usefulness.
• Propose a minimum sufficient logging profile for telecom agents.
• Validate the proposed profile on a small holdout set or through review with telecommunications subject-matter experts.
• Document the results, limitations, and recommendations for future development.

The skills you bring:

• You are studying Computer Science, Data Science, Computer Engineering, Electrical Engineering, or a related field.
• You have solid Python programming skills.
• You are interested in careful experimental design, observability, and AI systems.
• You have good analytical, problem-solving, and technical writing skills.

The following knowledge or experience is considered a plus:

• Large language models or agent frameworks.
• Network operations or fault management.
• Software testing and failure analysis.
• AI governance, privacy, or responsible AI.
• Statistics, structured logging, or autonomous networks.

Keywords: machine learning, statistics, Python, AI agents, structured logging, failure attribution, and autonomous networks.
